Arduino refers to the open source hardware and software intended for artists, designers, and tinkerers of all kinds to build objects or interactive machines. The Arduino microcontroller was designed to be inexpensive and easily programmed - boards can be built by hand or purchased preassembled for as little as $20, and the software can be downloaded for free.
Arduino was designed to be accessible to everyone, and it seems to be working. The device has captivated a growing number of minds in the tech world and the mainstream since its release in 2005. It's been used to make everything from art to robots to breathalyzers to guitars. Recently, Microsoft Research announced it had figured out how to eliminate blurry photos by compensating for unintentional movement of the camera using sensor information gathered by an Arduino board.
Laboral Centro de Arte, Spain, commissioned the documentary about Arduino, set to be released this summer. The filmmakers announced they are almost done and released the trailer a few days ago, which hit BoingBoing and other aggregators yesterday. Arduino says the traffic bump was due to being featured on one of "the main tech blogs" but didn't say which one.
