Arduino is an easy and affordable way for beginners and professionals to create devices that can interact with their environment using sensors and actuators.
Arduino is open-source hardware. The reference hardware designs are distributed under the Creative Commons Attribution Share-Alike 2.5 license and are available on the Arduino website. Schematics and component layout files (PCBs) for some board versions are also available.
Although the hardware and software designs are available under copyleft licenses, the developers have requested that the name Arduino be exclusive to the official product and not be used for derivative works without prior permission.
Most Arduino boards consist of an 8-bit Atmel AVR microcontroller (ATmega8, ATmega168, ATmega328, ATmega1280, ATmega2560); each microcontroller has varying amounts of flash memory, pins, and features. The boards use one- or two-row female headers/pins that facilitate connections and integration into other circuits.
