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.

What Arduino can do

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 running on a computer (e.g. Flash, Processing, MaxMSP).

The boards can be built by hand or purchased preassembled; the software can be downloaded for free. The hardware reference designs (CAD files) are available under an open-source license, you are free to adapt them to your needs.


The community of Arduino enthusiasts is vast, and includes region specific groups and special interest groups. The community is an excellent further source of support on all topics such as accessory selection, project assistance, and ideas of all sorts.

The Arduino Wiki (Playground) is a collection of Arduino knowledge, tutorials, and instructions provided directly by Arduino users.
