Arduino is an open-source hardware platform for building interactive electronic projects. It consists of a simple open hardware design with an Atmel processor and input/output support. The hardware is less expensive than other prototyping devices. It is accompanied by a software side written in Java and based on Processing. Arduino began in Italy to control student-built interaction design projects and is descended from the open-source Wiring platform. It has a large community and potential for growth supporting its future success.
