The Arduino is a small programmable device that can hold a small program and perform tasks such as reading temperature sensors, turning on or off switches, and can even serve as the ‘brain’ for a robot. I have used the Arduino (actually freeduino) for projects related to HVAC and hydroponics automation.

Usually I work only with the software, I’m not an expert of the hardware, but the excellent presentation by Riccardo Lemmi made me want to read a bit of material on the world of open hardware in general and Arduino in particular.
Open source hardware ( OSHW ) consists of physical artifacts of technology designed and offered in the same manner as free and open source software (FOSS). Open source hardware is part of the open source culture movement and applies a like concept to a variety of components. The term usually means that information about the hardware is easily discerned. Hardware design (i.e.schematics, bill of materials and PCB layout data) in addition to the software that drives the hardware are all released with the FOSS approach .
