i need help whith a code and wiring and i am a noob so if you can help me.
You don't really give enough detail about what you want to do.
FYI: "Exhibition" is about showing off what you have done.
If you are a noob and want to learn more, there are some really good documents and even books available. Nothing says you can't just "read" for a while before you start experimenting.
Good places to start:
pwillards right just read before you start experimenting. I started reading 1 year befor i got my arduino.
also for hardware questions they should be in the interfacing section
thanks you guys i will work on ling more of the basic
