Arduino is an open-source hardware and software platform where users can create tremendous electronic projects using programming via Arduino IDE, which users need to download directly from Arduino.cc. Since Arduino is open source, ELEGOO got the chance to make the same UNO R3 board which is fully compatible with Arduino.<br><br> The Upgraded Electronic Fun Kit is used as an extension kit for ELEGOO UNO R3 board or MEGA 2560 board and if you dont have one you can buy one from our store. <br><br> Component listing: <br>1pcs Power Supply Module <b> WARNING: Pls. do not use the voltage higher than 9V </b> <br>1pcs 830 tie-points Breadboard <br>1pcs 65 Jumper Wire <br>140pcs Solderless Jumper Wire <br>20pcs Female-to-male Dupont Wire <br>2pcs Pin header (40pin) <br>1pcs Precision Potentiometer <br>2pcs Photoresistor <br>1pcs Thermistor <br>5pcs Diode Rectifier (1N4007) <br>5pcs NPN Transistor (PN2222) <br>1pcs IC 4N35 <br>1pcs IC 74HC595 <br>1pcs Active Buzzer <br>1pcs Passive Buzzer <br>10pcs Button (small) <br>10pcs 22pf Ceramic Capacitor <br>10pcs 104 Ceramic Capacitor <br>5pcs Electrolytic Capacitor (10UF 50V) <br>5pcs Electrolytic Capacitor (100UF 50V) <br>10pcs White LED <br>10pcs Yellow LED <br>10pcs Blue LED <br>10pcs Green LED <br>10pcs Red LED <br>1pcs RGB LED <br>10pcs Resistor (10R) <br>10pcs Resistor (100R) <br>30pcs Resistor (220R) <br>10pcs Resistor (330R) <br>10pcs Resistor (1K) <br>10pcs Resistor (2K) <br>10pcs Resistor (5K1) <br>10pcs Resistor (10K) <br>10pcs Resistor (100K) <br>10pcs Resistor (1M) <br><br><br>
