Introduction
Arduino Controller is an All-in-One microcontroller especially designed for robotics application. Benefit
from Arduino open source platform, it is supported by thousands of open source codes, and can be easily
expanded with most Arduino Shields.Arduino can sense the environment by receiving input from a
variety of sensors and can affect its surroundings by controlling lights, motors, and other actuators. The
microcontroller on the board is programmed using the Arduino programming language (based on Wiring)
and the Arduino development environment (based on Processing). Arduino projects can be stand-alone
or they can communicate with software running on a computer (e.g. Flash, Processing, MaxMSP).
