Im a noob, and find hardware a bit a of a learning curve for myself.. so take my advice for what its worth
alot of the tutorials posted here are good to start with.. along with some beginner books.
I suggest getting a small kit or a general electronics kit (ie: resistors, capacitors, leds, jumper wires, sensors, breadboard..etc)
and follow along with the beginner lessons, form beginning to end.. (dont skip)..
I really found this place a good resource/reading and has a bunch of fun/practical lessons to go through:http://tronixstuff.wordpress.com/
this is place is GREAT, and full of very intelligent people/mods,..just dont be lazy and show you have given an honest effort, and people will gladly help you with questions.
