Arduino Open-source Electronics Prototyping

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.

Arduino

The Arduino board is a cheap, robust i/o board based on the ATmega168. It has 13 digital pins (6 of which allow PWM output) and 6 analog inputs. There are USB, serial, bluetooth, and mini versions,

Build. Schematics and PCB layouts. Assembly instructions: soldering a PCB or on a breadboard (either way, you'll need a bootloader).

The open-source Arduino Environment makes it easy to write code and upload it to the i/o board. It runs on Windows, Mac OS X, and Linux.

Download. From the software page. Learn. From the tutorials.
