Arduino is a prototype platform for creation of interactive projects. The Arduino microprocessor is programmed using the open source Arduino programming language. The processor can also receive input from sensors as well as communicating with software running on a computer. As output, it can control lights and motors. All of these factors make it appealing to individuals who practice producing homebrew projects and hacks.

Most microprocessor platforms perform many of the same functions as the Arduino board. However, Arduino has a few advantages over other platforms in that it is inexpensive, has cross-platform interoperability and is coded using open source software. In fact, even the hardware is open source. This allows much greater flexibility when working up a hack projects with Arduino, especially when compared to other boards such as the Netmedia's BX-24 or MIT's Handyboard.Official Site: Introduction
