Arduino is the brains of your next great project. This powerful microprocessor board can be easily and quickly programmed through open-source software, free to download from www.arduino.cc. The board itself is also open-source, which means you can learn exactly how its made and use its design as the starting point for your own design of circuits. Arduino is intended to create interesting and interactive projects, taking inputs from a variety of switches or sensors, and controlling a variety of lights, motors, and other physical outputs. Specifications: Microcontroller: ATMEGA328P Operating voltage: 5V Input voltage: 7-12V Digital I/O: 14 (6 provide PWM outputs) Analogue inputs: 6
