How to program an Arduino? Need help troubleshooting.
I am having some trouble getting an Instructable (Cat Genie hack) based on an Arduino board to work. This is the first microprocessor project I've ever tried and I am hoping someone here might be able to help me troubleshoot. I figured by posting the question here I might be able to get more help, faster, and from people who have experience with Arduino code. If I can't get it to work with a simple code fix I'm hoping I might be able to put something in the code that will allow me to troubleshoot where exactly the problem is occurring.
