Electro Schematics

This hands-on, peer-to-peer site contains more than a thousand electronics projects and circuits illustrated and enriched with photos, datasheets and easy-to-read schematics. Electro Schematics provides beginner tutorials as well as access to tested products and the latest information to ensure design success. Most important, by breaking projects down into step-by-step descriptions, the site answers two fundamental questions: How does it work, and how do you build it? Major categories of tutorials coverage includes Arduino, Atmel AVR microcontrollers, and Microchip PIC microcontrollers, and the topics include solar, power, lighting, alarms, radio. The site also maintains links to useful tools.
