Peter and Mark
Thanks I have a hard time coming up with simple solutions to my problems... I hope this gets better with time. Mark I understand that code in setup runs once but is there a reason why putting that for loop in Loop() is a bad idea? I want to learn do's and don't of Arduino. I've use the for loop in WinAvr.
Can you recommend books, or web sites to help learn the best approach solving the task needed?
I knew of modus arithmetic but wasn't sure how to use it.
