Arduino Basics

I just came across this site today ( www.schematics.com ).It looks pretty impressive !! Schematics.com allows you to "build, share and view schematics from you browser" You can also embed your schematic creations on your website - which is neat.         Circuit Diagram - Schematics is the language of electronics. It provides a concise and comprehensive diagrammatic description of a circuit. Schematics.com allows users to connect and share designs and ideas in a like-minded community.
