A Basic Introduction To Arduino

Arduino is avr based microcontroller board that has all necessary circuit to run atmega328p microcontroller. It is very easy to use and breadboard compatible. Arduino IDE is used to write code and upload it to Arduino board.There is variety of board available in the market like Arduino Uno, Arduino Mega, Arduino Nano, Arduino Mini, Arduino Micro and Arduino Lilypad. Here i am giving specification of Arduino Uno.

         Arduino Uno Specification
