... an evolving index of practical subjects for the Arduinotm and Freeduino microcontrollers, as found in the Arduino site, Playground wiki, forum and that big WWW thing.
Everything you read here will work on Freeduino, Arduino, Barebones, Boarduino or RBB boards, although slight modifications will occasionally be required between physical platforms.
