http://www.adafruit.com/ This site is fantastic for tutorials, resources, all help imaginable in fact. They have videos, live shows and amazing products. They create their own components as well as sell others, and all products are tried and tested (and broken apart) before they sell them. Complete idols here for their hard work, passion and dedication.Recently teamed up with Arduino.cc to manufacture Arduino.cc boards so watch this space too.
