Again any help with starting to program my IR sensor would be much appreciated, it's basically the only thing holding me back. I just need to know how to send out the pulse, read it return, and react accordingly. Are there any libraries, guides (that don't focus on remotes), hints? I honestly have no idea what I'm doing otherwise I would have given any code I could have created for this. I'll update as I learn more. Just getting nervous as the competition is in a few days.
