Arduino Uno Rev 3
The Micro controller that started it all
The Arduino Uno is the ubiquitous open-source micro-controller board, based on the Microchip ATmega328P micro controller, that began the micro-controller revolution. The board has 14 digital I/O pins (six capable of PWM output), 6 analog I/O pins, and is programmable with the Arduino IDE (Integrated Development Environment), via a type B USB cable. The Arduino UNO Rev3 is powered by a USB cable or by an external 9-volt battery. The Arduino eco-system means there is a plethora of add-on boards and shield available for the Arduino that can be leveraged in your projects.
