Thanks guys, I think am getting enlightening to " brink without delay " ,I will class myself a bit before continuing my project.
While you're at it load, read, and try running -all- of the ~/examples. Some you may not have the hardware for, but read them anyway just to see what they do. That's just to 'click' them in you head so that when you have a question about that kind of topc later you'll know to go there first to look for an example/answer.
