… an evolving index of practical subjects for the Arduino and Freeduino microcontrollers, as found in the Arduino site, Playground wiki, forum and that big WWW thing. Everything you read here will work on Arduino, the many versions of Freeduino, the Barebones and RBBB, the Boarduino, the iDuino and MAXserial, the eauDuino, the Jeenode, the many Arduino-compatible boards listed below, and of course the new-kids-on-the-block, the Sanguino, the Freeduino EPIC and the Arduino MEGA. Because of the different hardware layouts of these boards, slight modifications will occasionally be required between physical platforms.

Last update: July 7th, 2010. Serving over 19,000 unique Arduino/Freeduino junkies a month without charge or adverse side effects since August 2007! To suggest a link, email us!
