It really did walk a couple years ago when I did this, but has since stalled out on my latest attempt yesterday. Had to be something I goofed up.
Circuit Breaker - While I was looking for the PCB's I thought I had seen for the traffic lights I found this. What do you all think of it? Looked interesting, but I don't know enough to tell anything about it. I have done some of the circuits on this website and they have all worked, so I think this guy is pretty good. He also offers PCB's for a few other items including a single traffic light. Sorry, I am easily distracted sometimes...
