Need some info on a simple timer..............
(OP)
I am looking for an easy circuit to build to monitor a CubKar race. The Cubs (Boy Scouts) build a small car out of wood (8"x2"). The cars are raced, four at a time, down a track that starts off with a 4 foot sloped section and then a long flat sections. A level is used to release all four car at once and the first one to reach the end of the track wins. I know the circuit should be simple but I am a little rusty at my electronics. I through a simple LED sensors that can detect frist ,second or third car to past the finish line. Indicating the them by setting of lights in different flashing order. I like to use this to teach the cubs a bit about electronics at the same time.
So if you help it would be greatly appreciate.

Probably, the best approach will be over optical sensors. Is there any budgetary constraint?

and type "optical sensor" under Product / Service, which will return Sensors: Optical aligned with 142 Companies among other choices. Vision sensors could be considered. This way you can find "best possible" deal.
