Publisher review:Arduino is an open-source electronics prototyping platform based on flexible and easy-to-use hardware and software. It is developed especially for artists, designers, hobbyists and anyone interested in creating interactive objects or environments. It consists of a development environment (IDE) and the core libraries.
The application can sense the environment by receiving input from a variety of sensors and can affect its surroundings by controlling lights, motors, and other actuators.
Operating system:Mac OS X 10.3.9 or later
