Sparkfun Starter Kit for Arduino - Flex Arduino Uno - the latest Arduino USB board, fully assembled and tested Miniature breadboard - Excellent for making circuits and connections off the Arduino. Breadboard may come in various colors. Male to Male jumper wires -High quality wires that allow you to connect the female headers on the Arduino. SoftPot - Measure position along the softpot by looking at the change in resistance. It's like a touch sensitive volume slider. Photocell - A sensor to detect ambient light. Perfect for detecting when a drawer is opened or when night-time approaches. Thermistor - A sensor for detecting ambient temperature and temperature changes. Tri-Color LED - Because everyone loves a blinky. Use this LED to PWM mix any color you need. Basic LEDs - Light emitting diodes make great general indicators. Linear trim pot -This is a device commonly used to control volume, contrast, and makes a great general user control input. 330 Ohm Resistors - 5 current limiting resistors for LEDs, and strong pull-up resistors. 10k Ohm Resistors - These make excellent pull-ups, pull-downs, and current limiters
