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.

You did the right thing to ask on the instructable itself: if it's not a hookup problem, and its compiling correctly - I really can't think of anything other than a new cartridge revision...

Thanks for the reply. Someone just recently sent me a message on the instructable. It would appear I had two of my leads switched around... rookie mistake big time. I'm still not sure if one of the pictures on it was just flat wrong. The unit works now, but the success indicator light still doesn't come on when it is done. This is a problem other people were having, so I'll look back through the posts on there and hopefully get it fixed up. In any case, it does work, so even if the light doesn't come on... oh well.
