I've got a few projects that I feel an Arduino would be perfect for, but I'm having trouble figuring out what I need.
I need a small micro controller that can switch a 5v current off and on, and can receive a signal over ip via either ethernet or wifi. I'd like to be programmable over USB, but that's it. No processor speed restrictions or anything. I really just want a remote 5v tripper. I'm not sure exactly what I need, but I figure someone here might!
