Base Grid

A large clear base grid is included with this kit to help keep the circuit blocks properly spaced. You will see evenly spaced posts that the different blocks snap into. You do not need this base to build your circuits, but it does help in keeping your circuit together neatly. The base has rows labeled A-G and columns labeled 1-10. The base grid functions like the printed circuit boards found in most electronic products. It is a platform for mounting parts and wires (though the wires are usually "printed" on the board).
Pencil Alarm

Project Number: 81

OBJECTIVE: To draw an alarm activator.

Description: Build the circuit shown and connect the two jumpers to it, leave the loose ends of the jumpers unconnected for now. There is one more part you need and you are going to draw it. Take a pencil (No. 2 lead is best but other types will also work). SHARPEN IT, and fill in the shape below. You will get better results if you place a hard, flat surface directly beneath this page while you are drawing. Press hard (but don't rip the paper), and fill in the shape several times to be sure you have a thick, even layer of pencil lead.

Turn on the slide switch (S1) and take the loose ends of the jumpers, press them to the shape and move them around over the drawing. If you don't hear any sound then move the ends closer together and move over the drawing, add another layer of pencil lead, or put a drop of water on the jumper ends to get better contact.

Light-Controlled Sounds (V)

Project Number: 65

OBJECTIVE: To show a variation of the circuit in Project #61.

Description: Now remove the connection between U & Z, add a 1-snap at Z (on level 3), add a second 3-snap between V & W (on level 3), and finally place the music IC (U1) directly over the alarm IC (U2) on level 4. Listen to the sounds.
Paper Space War

Project Number: 21

Parts Needed For Circuit: Piece Of Paper With Lots Of Dark Areas On It (Not Included)

OBJECTIVE: To give a more dramatic demonstration of using the photoresistor.

Description: Use the same circuit as for Project #20. Find a piece of white paper that has a lot of large black or dark areas on it, and slowly slide it over the photosensitive resistor. You should hear the sound pattern constantly changing, as the white and dark areas of the paper control the light to the photosensitive resistance. You can also try the pattern below or something similar to it:
Really Wacky Sounds

Project Number: 94

OBJECTIVE: To combine different sounds.

Description: Build the circuit shown. Turn it on, press the press switch (S2) several times, and wave your hand over the photoresistor to hear all the sound combinations. You can make the sound from the music IC louder by replacing the 100 ohm resistor (R1) with the 2.5V lamp (L1).
Two-Speed Fan

Project Number: 13

Parts Needed For Circuit: B1, M1, Fan Blade, S2, L1, 2, S1, 2, 1, 1, 2, 2, 2, 2

OBJECTIVE: To show how switches can increase or decrease the speed of an electric fan.

Description: Build the circuit shown on the left by placing all the parts with a black 1 next to them on the board first. Then, assemble parts marked with a 2. Finally, add the 2-snap wires that are marked for level three. When you close the slide switch (S1), current flows from the batteries through the slide switch (S1), motor (M1), The lamp (L1), and back to the battery (B1). When the press switch (S2) is closed, the lamp is shorted and the motor speed increases. The principle of removing resistance to increase motor speeds is only one way of changing the speed of the motor. Commercial fans do not use this method because it would produce heat in the resistor and fans are used to cool circuits by moving air over them. Commercial fans change the amount of voltage that is applied to the motor using a transformer or other electronic device.
Light-Controlled Sounds

Project Number: 61

OBJECTIVE: To give a more dramatic demonstration of using the photosensitive resistance.

Description: Build the circuit shown on the left. Turn on the slide switch (S1), a police siren is heard. The loudness of the sound depends on how much light reaches the photoresistor (RP), try partially shielding it or placing it near a very bright light, and compare the sound.
Light Police Siren

Project Number: 22

Parts Needed For Circuit: B1, 4, 6, U2, U1, 5, 1, SP, S1, 3, 2, RP, 3, 2, 2, 2

OBJECTIVE: To build a police siren that is controlled by light.

Description: Build the circuit shown on the left by placing all the parts with a black 1 next to them on the base grid first. Then, assemble parts marked with a 2. Finally, insert the parts with a 3 last on level 3. Cover the photoresistor (RP) and turn on the slide switch (S1). A police siren with music is heard for a while and stops, then you can control it by covering or uncovering the photoresistor.
The Fuse

Project Number: 14

Parts Needed For Circuit: All The Parts Used From Project #13

OBJECTIVE: To show how a fuse is used to break all current paths back to the voltage source.

Description: Use the circuit built in Project #13. When you close the slide switch (S1), current flows from the batteries, through the slide switch (S1), the lamp (L1), motor (M1), and back to the battery (B1). Pretend the 2-snap wire marked fuse in the drawing on the left is a device that will open the circuit if too much current is taken from the battery. When the press switch (S2) is closed, the light is shorted and the motor speed increases due to an increase in he current to the motor. While still holding down the press switch (S2) down, remove the 2-snap wire marked fuse and notice how everything stops. Until the fuse is replaced, the open circuit path protects the electronic parts. If fuses did not exist, many parts could get hot and even start fires. Replace the 2-snap wire and the circuit should return to normal. Many electronic products in your home have a fuse that will open when too much current is drawn. Can you name some?
Quieter Reflection Detector

Project Number: 52

OBJECTIVE: To detect a mirror.

Description: Build the circuit on the left. Place it where there won't be any light hitting the photoresistor (RP) (such as in a dark room or under a table), and then turn it on. The 2.5V lamp (L1) will be bright and one song may play, but then there should be no sound. Take a small mirror and hold it above the lamp and photoresistor. You should hear sound now. You have a reflection detector! You can also use a white piece of paper instead of a mirror, since white surfaces reflect light.
Periodic Sounds

Project Number: 38

OBJECTIVE: To build a circuit with light and sound that change and repeat.

Description: Build the circuit shown on the left and turn it on. The lamp (L1) alternates between being on and off while the speaker (SP) alternates between two musical ones . . . like someone is flipping a switch, but at a very constant rate. Periodic signals like this are very important in electronics.
Decreasing Saucer Lift

Project Number: 12

Parts Needed For Circuit: L1

OBJECTIVE: To show how voltage affects the speed of a DC motor and can decrease the lift of the saucer.

Description: Change the circuit in Project #11 by adding the lamp (L1) in series with the motor as shown in the diagram on the left. When you place the lamp in series with any electronic device, it will draw less current because it adds resistance. In this case, the lamp in series reduces the current through the motor, and that reduces the top speed of the motor. Close the slide switch (S1), and wait until the fan reaches maximum speed. Open the switch and observe the difference in the height due to the lamp. In most cases, it may not even launch.
Integrated Circuits

Some types of electronic components can be super-miniaturized, allowing thousands of parts fit into an area smaller than your fingernail. These "integrated circuits" (ICs) are used in everything from simple electronic toys to the most advanced computers. The music, alarm, and space war ICs (U1, U2, and U3) in Snap Circuits are actually modules containing specialized sound-generation ICs and other supporting components (resistors, capacitors, and transistors) that are always needed with them. This was done to simplify the connections you need to make to use them. The description for these modules are given here for those interested, see the projects for connection examples:

Music IC (U1)

Debut: Sound Activated Switch

Alarm IC (U2)

Debut: Space War Alarm Combo

Space War IC (U3)

Debut: Space War Alarm Combo
Electric Light & Switch

Project Number: 1

Parts Needed For Circuit: B1, L1, 3, S1, 2, 2, 2, 2

OBJECTIVE: To show how electricity is turned "ON" or "OFF" with a switch.

Description: Build the circuit shown on the left. Place all the parts with a black number 1 next to them on the base grid at first. Then, assemble the pieces marked with a 2. Install two (2) "AA" batteries (not included) into the battery holder (B1). When you close the slide switch (S1), current flows from the batteries through the lamp and back to the battery through the slide switch. In electronics, this is called a closed circuit. When the slide switch is off, the current can no longer flow back to the battery, so the lamp goes out. In electronics, this is called an open circuit.
Noisier Water Space War

Project Number: 95

OBJECTIVE: To use water to control the space war integrated circuit.

Description: Add the press switch (S2) to the preceding circuit to make it look like the one on the left. There will be sound if the press switch is pressed or if the jumper wires are in the water. Pressing the press switch or pulling the wires out of the water changes the sound played. If you prefer, you can just touch the jumper wire metal with your finger instead of putting the jumpers in the water. Wet your fingers to get better electrical contact.

(NOTE: This circuit is named "Noisier Water Space War" because Project #92 used to be "Water Space War", but it was dull and didn't always work, so it was replaced with "Wacky Sounds").
Sound-Controlled Time Delay LED

Project Number: 75

OBJECTIVE: To control an LED using sound.

Description: Use the circuit from Project #74. Connect the whistle chip (WC) to points A1 and C1 on the base grid, then remove the photoresistor (RP). Turn the slide switch (S1) on and clap your hands or talk loud near the whistle chip, the LED (D1) will light. The whistle chip has a piezocrystal between the two metal plates. The sound causes the plates to vibrate and produce a small voltage. The voltage then activates the music IC (U1).
Electronic Bombing Game

Project Number: 66

OBJECTIVE: To make an electronic bombing game.

Description: Build the circuit on the left. It uses both jumper wires as permanent connections. It also uses two 2-snap wires as "shorting bars". Setup: Player 1 sets the target by placing one shorting bar under the paper on row B, C, or D. Player 2 must NOT know where the shorting bar is located under the paper. The object is for Player 2 to guess the location by placing his shorting bar at positions X, Y, or Z. In the drawing on the left Player 1 set up this hole at position "D". If Player 2 places his shorting bar across "Z" on the first try then he gets a hit. He keeps guessing until he hits. After each hit, remove the shorting bars and slide the switch off and on to reset the sound. Player 2 then sets the B, C, D side and Player 1 tries his luck. Play multiple rounds and see who gets the best overall score. The winner will be the player who is best at reading his opponent's mind.
Speaker

The speaker (SP) converts electricity into sound. It does this by using the energy of changing electrical signal to create mechanical vibrations (using a coil and magnet similar to that in the motor), these vibrations create variations in air pressure which travels across the room. You "hear" sound when your ears feel these air pressure vibrations.
Light/Water Space War

Project Number: 96

OBJECTIVE: To use water to control the space war integrated circuit.

Description: Use the circuit from Project #95. Replace the speaker (SP) with the LED (D1), positioning it as in Project #89. Putting the jumper wires in the water OR pressing the press switch (S2) will cause the LED to be bright.
Motor

The motor (M1) converts electricity into mechanical reaction. Electricity is closely related to magnetism, and an electric current flowing in a wire has a magnetic field similar to that of a very, very tiny magnet. Inside the motor is three coils of wire with many loops. If a large electric current flows through the loops, the magnetic effects become concentrated enough to move the coils. The motor has a magnet inside so, as the electricity moves the coils to align them with the permanent magnet, the shaft spins.
Race Game

Project Number: 57

OBJECTIVE: Build an electronic game for racing.

Description: Modify Project #56 by adding the pointer as shown on the left. The paper should be cut from page 46 and taped high enough on the speaker (SP) so the pointer will stick over the fan (M1) with paper. Bend the pointer at a right angle as shown on the left. Setup: Cut out the grid with four (4) colors from page 46 and place it under the base as shown on the left. Each player picks a color (or two colors if only 2 people are playing) and places a single snap on row G. The purple player in column 1, the blue player in column 2, the green player 3, and the yellow player in column 4 will be playing. Spin the wheel by closing the press switch (S2). The first single color wedge that the pointer points to is the first player to start. In some models, you only have three 1-snaps, so use a 2-snap if you have four players. The Play: Each player gets a turn to press the press switch. They release the press switch and when the pointer points to a wedge the players that match the colors on the wedge gets to move up one space. If a liner comes up like the one shown on the left then the players on each side of the line gets to move up two (2) spaces. The first player to reach the top row (A) wins. If two players reach the top row at the same time they must both drop down to row "D" and the play continues.

(NOTE: If you have Snap Circuits Classic (Electronic Snap Circuits), Pro, or Extreme you can use four (4) 1-snaps because you have six (6) 1-snaps in these models).

Parts Needed For Circuit: B1, 5, SP, U1, 4, S1, 2, 2, S2, 3, 2, 2

OBJECTIVE: To show how integrated circuits can also create loud alarm sounds in case of emergencies.

Description: Modify the circuit used in Project #15 to look like the one shown on the left. When you close the slide switch (S1), the music integrated circuit (U1) may start playing one song then stop. The song will be much louder than in the previous project because it is now being used as an alarm. Each time you press the press switch "alarm button" (S2) after the song stops playing, the song will play again, but only while you hold the button down.
Ambulance Contact Alarm

Project Number: Last (101)

OBJECTIVE: To show a variation of the circuit in Project #98.

Description: The same circuit also detects if the jumper wires get touched together, so connect to each other. The tone of the sound is now much different. Therefore, this circuit will tell you if there is water between the jumper wires or if the wires are touching each other.

Space War

Project Number: 19

Parts Needed For Circuit: B1, 5, U3, 4, 3, SP, 3, S2, 3, S1, 2

OBJECTIVE: To introduce you to the space war integrated circuit and the sounds it can make.

Description: Build the circuit shown on the left, which uses the space war integrated circuit (U3). Activate it by flipping the slide switch (S1) or pressing the press switch (S2); do both in combination. You will hear an exciting range of sounds, as if a space war is raging! Like the other integrated circuits, the space war IC is a super-miniaturized electronic circuit that can play a variety of cool sounds stored in it by using just a few extra components. In movie studios, technicians are paid to insert these sounds at the precise instant a gun is fired. Try making your sound occur at the same time an object hits the floor. It is not as easy as it sounds.
Space Battle (II)

Project Number: 36

OBJECTIVE: To show another way of using the space war integrated circuit.

Description: Build the circuit shown on the left, which is based on the circuit in the Space War Project #19. Turn on the switch and you will hear exciting sounds, as if a space battle is raging! The moor is used here as a 3-snap wire, and will not spin.
Fun with the Alarm IC

Project Number: 83

OBJECTIVE: To show some new ways of using the alarm IC.

Description: Build the circuit shown and place the fan on the motor (M1), but leave the jumpers off for the time being. Turn on the slide switch (S1) and tap the whistle chip (WC), it makes a machine gun sound (with music in the background). Thoroughly cover the photoresistor (RP) with your hand and the sound becomes a siren. With the photoresistor covered, press the press switch (S2) and the sound becomes that of an ambulance. Uncover the photoresistor and the sound remains that of a machine gun whether the press switch is pressed or not. After a while the sound will stop, tap the whistle chip and it resumes. Connect the two jumpers as shown and tap the whistle chip to resume the sound. The lamp (L1) and the LED (D1) light and the motor spins. The sound continues, but it may become distorted as the motor speeds up. The motor draws a lot of power from the batteries (B1), and this may reduce the voltage to the music (U1) and alarm (U2) ICs, distorting the sound. The sound may even stop if your batteries are weak.
Voice Light Diode

Project Number: 32

OBJECTIVE: To build a circuit that uses your voice to control a light emitting diode.

Description: Build the circuit shown on the left and turn on the slide switch (S1). The LED may be on for a while and then turn off. Clap or talk loud and the LED will light again and keep flickering for a little while.
Flying Saucer

Project Number: 11

Parts Needed For Circuit: All The Parts Used From Project #2, Polarity Reversed On M1

OBJECTIVE: To make a circuit that launches the fan blade to simulate a flying saucer.

Description: Rebuild the circuit from Project #2, but reverse the polarity on the motor (M1) so the negative (-) goes to the positive (+) on the battery (B1). New alkaline batteries are recommended for this project. When you close the slide switch (S1) the motor will slowly increase in speed. When the motor has reached maximum rotation, turn the slide switch off. The fan blade should rise and float through the air like a flying saucer. Be careful not to look directly down on the fan blade when it is spinning. The air is being blown down through the blade and the motor rotation locks the fan on the shaft. When the motor is turned off, the blade unlocks from the shaft and is free to act like a propeller and fly through the air. If the speed of the rotation is too slow, the fan will remain on the motor shaft because it does not have enough lift to propel it. The motor will spin faster when both batteries are new. If the fan doesn't fly off, then turn the switch on and off rapidly when it is at full speed.
Lamp & Fan in Series

Project Number: 5

Parts Needed For Circuit: B1, L1, M1, Fan Blade, 2, S1, 2, 2, 2

OBJECTIVE: To show how a lamp can indicate when a fan is running.

Description: Build the circuit shown on the left by placing all the parts with a black 1 next to them on the base grid first. Then, assemble parts marked with a 2. Finally, place the an blade on the motor (M1). When you close the slide switch (S1), the fan will spin and the lamp (L1) should turn on. The fan will take a while to start turning due to inertia. Inertia is the property that tries to keep a body at rest from moving and tries to keep a moving object from stopping. The light helps protect the motor from getting the full voltage when the slide switch is closed. Part of the voltage goes across the lamp and the rest goes across the motor. Remove the fan and notice how the lamp gets dimmer when the motor does not have to spin the fan blade.
Light Emitting Diode

Project Number: 7

Parts Needed For Circuit: B1, S1, R1, D1, 2, 2, 2, 2

OBJECTIVE: To show how a resistor and LED are wired to emit light.

Description: Build the circuit shown on the left by placing all the parts with a black 1 next to them on the base grid first. Then, assemble parts marked with a 2. When you close the slide switch (S1), current flows from the batteries (B1) through the slide switch, through the resistor (R1), through the LED (light emitting diode, D1) and back to the battery. The closed slide switch completes the circuit. The resistor limits the current and prevents damage to the LED. NEVER PLACE AN LED DIRECTLY ACROSS THE BATTERY! If there is no resistor in the circuit, the battery may push enough current through the LED to damage the semiconductor that is used to produce the light. LEDs are used in all types of electronic equipment to indicate conditions and pass information to the user of that equipment. Can you think of something you use everyday that has an LED in it?
NOT This AND That

Project Number: 50

OBJECTIVE: To demonstrate the concept of a NAND circuit.

Description: Build the circuit on the left and test the combinations of the slide switch (S1) and press switch (S2). If you compare it to the AND circuit in Project #48, you can see the LED (D1) lights in the opposite combinations of that circuit. Hence, we refer to it as a NAND circuit (short for "NOT this AND that"). This circuit can also have more or less than two inputs, though when it only has one input it is referred to as a NOT circuit. Like the OR, AND, NOR, NAND, and NOT are important building blocks in computers.
Musical Doorbell

Project Number: 15

Parts Needed For Circuit: B1, 6, SP, U1, D1, 5, S1, 2, R1, 3, S2, 1, 1, 2, 2, 2, 2

OBJECTIVE: To show how an integrated circuit can be used as a musical doorbell.

Description: Build the circuit shown on the left. When you close the slide switch (S1), the music integrated circuit (U1) may start playing one song then stop. Each time you press the press switch "doorbell button" (S2) the song will play again and stop. Even if you let go of the press switch (S2), the integrated circuit keeps the song playing until it has reached the end of the song. Musical integrated circuits are used to entertain young children in many of the toys and chairs made to hold infants. If the music is replaced with words, the child can also learn while they are entertained. Because of great advances in miniaturization, many songs are stored in a circuit no bigger than a pinhead.
Alarm Circuit

Project Number: 17

Parts Needed For Circuit: B1, 5, SP, U2, 4, S1, 2, 2, 3, 2, 2

OBJECTIVE: To show how an integrated circuit can be used to make real alarm sounds.

Description: Build the circuit shown on the left by placing all the parts with a black 1 next to them on the board first. Then, assemble parts marked with a 2. When you close the slide switch (S1), the integrated circuit (U2) should start sounding a very loud alarm sound. This integrated circuit is designed to sweep through all the frequencies so even hard of hearing people can be warned by the alarm. If the alarm sound was passed through an amplifier and installed into a police car, it would also serve as a good police siren.
Motor-Controlled Sounds

Project Number: 40

OBJECTIVE: To show how motion can trigger electronic circuits.

Description: This circuit is controlled by spinning the motor (M1) with your hands. Turn on the slide switch (S1). A police siren is heard and then stops. Spin the motor and it will play again. Note however, that music can be heard faintly in the background of the siren.
Motor Sounds Combo

Project Number: 84

OBJECTIVE: To connect multiple devices together.

Description: In the circuit, the outputs from the alarm and music ICs are connected together. Build the circuit shown and then place the alarm IC (U2) directly over the music IC (U1), resting on two 1-snaps and a 2-snap. Turn on the slide switch (S1) and you will hear a siren and music together while the lamp (L1) varies in brightness. Push the press switch (S2) and the fan spins, while the sound may not be as loud. The fan may rise into the air when you release the press switch.
Simple Water Alarm

Project Number: 98

OBJECTIVE: To sound an alarm when water is detected.

Description: Build the circuit shown but initially leave the jumper wires outside the cup. Turn on the slide switch (S1); nothing happens. Place the jumper wires into a cup of water and an alarm sounds! You could use longer wires and lay them on your basement floor, if your basement floods during a storm, then this circuit will sound an alarm.
This OR That

Project Number: 47

OBJECTIVE: To introduce you to the OR concept of electronic wiring.

Description: Build the circuit shown. Notice that if you turn on the slide switch (S1) OR press the press switch (S2) the LED (D1) lights up. There is no partially lit state here, the diode is either totally on or totally off. While this may seem very simple and boring, it represents an important concept in electronics. Two switches like this may be used to turn on a light in your house, or they might be two sensors at a railroad crossing used to start the ding-ding sound and lower the gate. You could also have more than two switches and the circuit would function the same way.
Sound Activated Switch

Project Number: 3

Parts Needed For Circuit: B1, 5, U1, 4, S1, 3, WC, 2, 2, SP, Black & Red Jumper Wires

OBJECTIVE: To show how sound can turn "ON" an electronic device.

Description: Build the circuit shown on the left by placing all the parts with a black 1 next to them on the base grid first. Then, assemble parts marked with a 2. Finally, lay the speaker (SP) on the table and connect it to the circuit using the jumper wires as shown. When you close the slide switch (S1), the music may play for a short time, then stop. After the music has stopped, clap your hands close to the whistle chip (WC) or tap the base with your finger. The music should play again for a short time, then stop. Blow on the whistle chip and the music should play. You could connect the speaker using snap wires instead of the jumper wires, but then the speaker may create enough sound vibrations to re-activate the whistle chip.
Wacky Sounds

Project Number: 92

OBJECTIVE: To combine different sounds.

Description: In the circuit, the outputs from the alarm and music ICs are connected together. Build the circuit shown and place the alarm IC (U2) directly over the music IC (U1), resting on two 1-snaps and a 2-snap. There is also a 2-snap on top of the alarm IC. Turn on the slide switch (S1) and you will hear a siren and music together while the lamp (L1) varies in brightness.
Space War Alarm Combo

Project Number: 10

Parts Needed For Circuit: B1, L1, SP, U2, U3, 5, 1, 1, 2, 2, 2, 2, S2, 3, RP, 1, 4, 2, 3, 2, S1, Both Jumper Wires

OBJECTIVE: To combine the sounds from the space war and alarm integrated circuits.

Description: Build the circuit shown and add the jumpers to complete it. Turn it on, press the press switch (S2) several times, and wave your hand over the photoresistor (RP) to hear all the sound combinations. If the sound is too loud you may replace the speaker (SP) with the whistle chip (WC).
Pencil Alarm Variants

Project Number: 82

OBJECTIVE: To draw an alarm activator.

Description: Remove the jumper connected to point Y (as shown in the drawing) and connect it to point Z instead. Touch the loose ends to the pencil drawing again, the sound is different now. Next, connect a 2-snap wire between points X & Y. Then connect the jumper to either point. Touch the loose ends to the pencil drawing again, you hear a different sound. Now remove the 2-snap wire between X & Y and connect it between X & Z, and connect the jumpers to W & Y. Touch the loose ends to the pencil drawing again, you hear yet another sound. Now you can draw your own shapes and see what kinds of sounds you can make.
This AND That

Project Number: 48

OBJECTIVE: To introduce you to digital circuits.

Description: Build the circuit shown. Notice that if you turn on the slide switch (S1) AND press the press switch (S2) the LED (D1) lights up. Once again, there is no partially lit here, the LED is totally on or totally off. Two switches like this may be used to turn on the same light in your house, the room and the master switch in your electrical box. You could also have more than two switches and the circuit would function the same way. Combinations of AND and OR circuits are used to add and multiply numbers together in modern computers. These circuits are made of tiny transistors in massive integrated circuits.
Using Parts as Conductors

Project Number: 58

OBJECTIVE: To show that motors and lamps may sometimes be used as ordinary conductors.

Description: Turn on the slide switch (S1) and tap the whistle chip (WC), it makes a machine gun sound (with music in the background). Thoroughly cover the photoresistor (RP) with your hand and the sound becomes a siren. After a while the sound will stop, tap the whistle chip and it resumes. Press the press switch (S2) and the LED (D1) lights, but the lamp (L1) does not light and the motor (M1) does not spin. Electricity is flowing through the lamp and motor, but not enough to turn them on. So in this circuit they are acting like 3-snap wires.

(NOTE: This is the circuit printed on the kit's box cover, but you may place the fan blade on the motor (M1), but the fan will not spin, too.
Motor Sounds Combo (II)

Project Number: 85

OBJECTIVE: To connect multiple devices together.

Description: In the circuit, the outputs from the alarm and music ICs are connected together. Build the circuit shown and then place the alarm IC (U2) directly over the music IC (U1), resting on three 1-snaps. Turn on the slide switch (S1) and you will hear a siren and music together. Push the press switch (S2) and the fan spins, while the sound may not be as loud. The fan may rise into the air when you release the press switch. This circuit is similar to Project #84, but the fan will fly a little higher since the sound circuit no longer drives the lamp (L1) and therefore uses less battery power.
OR/AND Space War Light

Project Number: 97

OBJECTIVE: To control the space war integrated circuit.

Description: Use the circuit from Project #96. Replace the LED (D1) with the 2.5V lamp (L1). Putting the jumper wires in the water OR pressing the press switch (S2) will cause the lamp to be dimly lit. Putting the jumper wires in the water AND pressing the press switch at the same time will cause the lamp to be much brighter.
Voice Control

Project Number: 33

OBJECTIVE: To use your voice to control sounds.

Description: The preceding circuit probably did not seem too exciting; so replace the LED (D1) with the speaker (SP). You hear a range of exciting sounds. Clap or talk loud and the sounds will resume. If you find that the sounds do not turn off, the vibrations created by the speaker may be activating the whistle chip (WC). Set the speaker on the table near the circuit and connect it to the same locations using the jumper wires to prevent this.
More Sound Effects

Project Number: 46

OBJECTIVE: To investigate the different sound effects available from the alarm integrated circuit.

Description: Build the circuit shown on the left. When you close the slide switch (S1), the integrated circuit (U2) should start sounding an up-down siren. This is just one more sound effect that this integrated circuit is designed to produce. Different sounds that can easily be changed are very important when designing games and toys. Switch the sound on and off quickly to see if you can create even different effects. This mode will create many robotic sounds if switched quickly.
Light-Controlled Lamp

Project Number: 71

OBJECTIVE: To turn a lamp on and off using light.

Description: Cover the unit, turn the slide switch (S1) on, and notice that the lamp (L1) is off after a few seconds. Place the unit near a light and the lamp turns on. Cover the photoresistor (RP) and place it in the light again. The lamp will not turn on. The resistance of the photoresistor decreases as the light increases. The low resistance acts like a wire connecting point C to the positive (+) side of the battery (B1).
Reflection Detector

Project Number: 51

OBJECTIVE: To detect if a mirror is present.

Description: Build the circuit on the left. Place it where there won't be any light hitting the photoresistor (RP) (such as in a dark room or under a table), and then turn it on. The 2.5V lamp (L1) will be bright, but there should be no sound. Take a small mirror and hold it above the lamp and photoresistor. You should hear sound now. You have a reflection detector! You can also use a white piece of paper instead of a mirror, since white surfaces reflect light.
Light-Controlled Flicker

Project Number: 45

OBJECTIVE: To make a circuit that uses light to control the blinking of another light.

Description: This circuit does not use the noisy speaker (SP); it uses a nice, quiet LED (D1). Turn on the slide switch (S1), the LED flickers. Wait a few seconds, then cover the photoresistor (RP) and the flicker stops. The flicker is controlled by the photoresistor, uncover it and the flicker resumes. People who are deaf need lights to tell them when a doorbell is ringing. They also use circuits like this to tell them if an alarm has been triggered or if an oven is ready. Can you think of other uses?
Laser Gun

Project Number: 18

Parts Needed For Circuit: B1, 6, SP, U2, 5, S1, 2, R1, 3, 3, 2, 2

OBJECTIVE: To show how integrated circuit sounds can easily be changed to exciting space war sounds.

Description: Build the circuit shown on the left by placing all the parts with a black 1 next to them on the base grid first. Then, assemble parts marked with a 2. When you close the slide switch (S1), the integrated circuit (U2) should start sounding a laser gun sound. This integrated circuit is designed to produce different sounds that can easily be changed. You can even switch the sound on and off quickly to add sound effects to your games or recordings.

(NOTE: This article is not about violence, since "gun" may sound like a violent thing, but Snap Circuits is completely not about violence).
Lamp & Fan in Parallel

Project Number: 6

Parts Needed For Circuit: B1, 4, L1, M1, Fan Blade, 3, S1, 2, 2, 2, 2, 2

OBJECTIVE: To show how an indicator light can be connected without affecting the current in the motor.

Description: Build the circuit shown on the left. When you close the slide switch (S1), both the fan and the lamp (L1) should turn on. The fan will take a while to spin due to inertia. In this connection, the lamp does not change the current to the motor (M1). The motor should start a little faster than in Project #5. Remove the fan and notice how the lamp does not change in brightness as the motor picks up speed. It has its own path to the battery (B1).
Quiet Water Alarm

Project Number: 70

OBJECTIVE: To sound an alarm when water is detected.

Description: Sometimes you may want a water alarm that can be heard but not loud enough to be annoying or distracting, so let's make one. We'll also put a light on it that could be seen in a noisy room, in a real application you could use a powerful light that would be easily seen. Build the circuit shown but initially leave the jumper wires outside the cup. Turn on the slide switch (S1); nothing happens. Place the jumper wires into a cup of water and an alarm sounds and the light comes on.

Does this work?
Spin Draw

Project Number: 59

OBJECTIVE: To produce circular artistic drawings.

Description: Rebuild the simple motor connection as shown on the left. This is the same setup as Project #57. Setup: Cut out a circular piece of thin cardboard from the back of an old spiral or note pad. Use the fan blade as a guide. Place the fan on the cardboard and trace it around with a pencil or pen. Cut the cardboard out with scissors and tape it to the fan blade. Do the same thing with a piece of white paper, but tape the paper on top of the cardboard so it can be removed easily later. Drawing: To make a ring drawing obtain some thin and thick marking pens as drawing tools. Spin the paper by pressing and holding the press switch (S2) down. Press the marker on the paper to form rings. To make spiral drawings, release the press switch and as the motor (M1) approaches a slow speed move the marker from the inside outward quickly. Change the colors often and avoid using too much black to get hypnotic effects. Another method is to make colorful shapes on the disc then spin the disc and watch them blend into each other. When certain speeds are reached under fluorescent lights without electronic ballasts, the strobe principle shown in another project will produce strange effects and backward movement. Make a wheel with different spokes to see this strange effect. Adding more spokes and removing spokes will give different effects at different motor speeds.
Space War Music Combo

Project Number: 68

OBJECTIVE: To combine the sounds from the space war and music integrated circuits.

Description: Build the circuit shown and add the jumpers to complete it. Turn it on, press the press switch (S2) several times, and wave your hand over the photoresistor (RP) to hear all the sound combinations. If the sound is too loud you may replace the speaker (SP) with the whistle chip (WC).
Clap Sounds

Project Number: 27

OBJECTIVE: To build a police siren and other sounds that are controlled by clapping your hands.

Description: Build the circuit shown on the left by placing all the parts with a black 1 next to them on the base grid first. Then, assemble parts marked with a 2. Turn on the slide switch (S1) and a police siren is heard and then stops, clap your hands and it will play again. Note however that music can be heard faintly in the background of the siren. If clapping does not trigger the sound, tap the whistle chip (WC) with your finger.
Spinning Rings

Project Number: 55

OBJECTIVE: To build an electronic spinner.

Description: Setup: Cut out the disc on page 46 that looks like the one shown here. Using Scotch tape, attach the disc with the printed side up on the top of the fan blade. Place the fan blade on the motor (M1) as shown to the left and below. When the press switch (S2) is pressed, the arcs will turn into colored rings with a black background. Notice how the color drops in brightness when it is stretched to make a complete circle.
Lamp, Speaker & Fan in Parallel

Project Number: 80

OBJECTIVE: To show the power drop of components connected in parallel.

Description: Leave the fan off the motor (M1). Turn on the slide switch (S1), the motor spins and the lamp (L1) turns on. Place the fan on the motor and press the press switch. The lamp is not as bright now, because it takes more power from the batteries (B1) to spin the motor with the fan on it, which leaves less battery power available to light the lamp. If you have weak batteries, the difference in lamp brightness will be more obvious because weaker batteries don't have as much power to supply. The speaker (SP) is being used as a low-value resistance here to make the above effects more apparent.
Touch Light

Project Number: 90

OBJECTIVE: Build a circuit that turns an LED on and off using the whistle chip.

Description: Use the circuit from Project 89. Replace the photoresistor (RP) with the whistle chip (WC). Tap on the whistle chip and the LED (D1) flickers. Tap again and the LED may flicker for a longer time. See how long the LED will stay on.
DC Motor & Switch

Project Number: 2

Parts Needed For Circuit: B1, M1, Fan Blade, 3, S1, 2, 2, 2, 2

OBJECTIVE: To show how electricity is used to run a Direct Current (DC) Motor.

Description: Build the circuit shown on the left by placing all the parts with a black 1 next to them on the base grid first. Then assemble parts marked with a 2. When you close the slide switch (S1), current flows from the batteries (B1) through the motor (M1) making it rotate. Place the fan blade on the motor shaft and close the slide switch. The motor will rotate forcing the fan blade to move air past the motor. In this project, you changed electrical power into mechanical power. DC motors are used in all the battery equipment requiring rotary motion, such as a cordless drill, electric toothbrush, and toy trains that run on batteries just to name a few. An electric motor is much easier to control than gas or diesel engines.
Motor Space Sounds

Project Number: 34

OBJECTIVE: To build a circuit that uses a motor to activate space war sounds.

Description: Turn it on and wait for any sounds to stop then spin the motor (M1) and the sounds play again. Do you now why turning the motor makes the sound play? Actually, the DC motor is also a DC generator and when you turn it, the motor generates a voltage that triggers the sound circuits.
Snap Wires

The blue snap wires are just wires used to connect other components, they are used to transport electricity and do not affect circuit performance. They come in different lengths to allow orderly arrangement of connections on the base grid. There is also a 1-snap wire that is used as a spacer or for interconnection between different layers.

One Direction for LED

Project Number: 8

Parts Needed For Circuit: All The Parts Used From Project #7, polarity on D1 reversed

OBJECTIVE: To show how electricity can only pass in one direction through an LED.

Description: Rebuild the circuit from Project #7 but put the LED (D1) as shown on the left. When you close the slide switch, current should flow from the batteries (B1) through the resistor and then through the LED. When current flows through an LED, it lights up. Since the LED is in backwards, current cannot flow. The LED is like a check valve that lets current flow in only one direction. In this project, you changed the direction of current through the LED. An electronic component that needs to be connected in one direction is said to have polarity. Other parts like this will be discussed in future projects. Placing the LED in backwards does not harm it because the voltage is not large enough to break down this electronic component.
Light Switch

Project Number: 20

Parts Needed For Circuit: RP

OBJECTIVE: To show how light can control a circuit using a photoresistor.

Description: Use the circuit from Project #19 above, but replace the slide switch (S1) with the photoresistor (RP). The circuit immediately makes noise. Try turning it off. If you experiment, then you can see that the only ways to turn it off are to cover the photoresistor, or to turn off the lights in the room (if the room is dark). Since light is used to turn on the circuit, you might say it is a "light switch". The photoresistor contains material that changes its resistance when it is exposed to light. As it gets more light, the resistance of the photoresistor decreases. Parts like this are used in a number of ways that affect our lives. For example, you may have streetlights in your neighborhood that turn on when it starts getting dark and turn off in the morning.

Space War Flicker Motor

Project Number: 60

OBJECTIVE: To run the motor using the space war IC.

Description: Turn on the slide switch (S1) and the motor (M1) spins (you may need to give it a push with your finger to get it started). The sounds from the space war IC (U3) are used to drive the motor. Because the motor uses magnets and a coil of wire similar to a speaker, you may even hear the space war sounds coming faintly from the motor.
