PIC controlled traffic lights

Here's a pretty cool set of microcontroller-powered miniature traffics lights from one of our youngest members. He's building an electronic toy set for his younger brother for Xmas and is using these to get starting with PIC programming.

Note how the sequence accurately follows a real set of lights - including that frustrating delay when both sets of lights stay red for a second or so - just in case any last-second idiots are trying to jump the amber light and squeeze through before the second stream of traffic is released!
