The Electronics

I did this project before I knew much about electronics so instead of trying to make the light control circuit I searched the Internet for a traffic light sequencer. This turned out to be a little harder to find that I had originally thought it would be. After finding a few that just made the lights flash on/off I found one that actually flashed them in the correct order from trafficlights.com (The link here goes to a newer version that can provide more power than the one I got, but it still looks to be of similar design). I quickly ordered it and connected it in.

The Heart
It worked like a charm. One thing I added that they didn't have was an in-line fuse for the AC power. Maybe it isn't really needed, but I try to put some sort of protection in-line to try and prevent me from burning down my place if I messed something up.
