+Description: The Arduino libraries and the development environment
+ Arduino is an open-source electronics prototyping platform based on flexible,
+ easy-to-use hardware and software. It's intended for artists, designers,
+ hobbyists, and anyone interested in creating interactive objects or
+ environments.
+ .
+ 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 on running on a computer
+ (e.g. Flash, Processing, MaxMSP).
