... 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.
Last update: May 9th, 2009. Serving over 10,000 unique Arduino/Freeduino junkies a month without charge or adverse side effects since August 2007. To suggest a link,
Everything you read here will work on Arduino, the many versions of Freeduino, the Barebones and RBBB, the Boarduino, the iDuino and MAXserial, the many Arduino-compatible boards listed below, and of course the new-kids-on-the-block, the Sanguino and the Arduino Mega. Because of the different hardware layouts of these boards, slight modifications will occasionally be required between physical platforms.
**Brian Evans shows his genius and generosity with the Arduino Programming Notebook. You can get a printed copy for only $5.33 at Lulu, or save paper and download the PDF instead for FREE! (**Updated to V6)
**News Flash: We no longer link to Arduino/Freeduino variants that do not provide design-level PCB files!
(It's not called sort-of-open-source hardware...)
