If you are a beginner with electronics, I highly reccommend two sources you'll want to investigate:
http://www.earthshineelectronics.com/files/ASKManualRev4.pdf
Basically, its the Earthshine Electronics (UK) Arduino Beginners Manual - a great thing to read, by the way! They have a starters kit that goes with it, you might check it out.
This is the "Electronics Club" - which is a great place to learn basic electronics skills (mainly geared toward a UK and European audience).
Good luck!
