    I have scoured the internet trying to find a circuit that uses a stopwatch and some sort of motion detector. I think I may have found one, but I don't know if it will work. Can anyone direct me to a project that uses a stopwatch and a motion sensor to start and stop it. I was thinking something like crossing a laser beam to start/stop the watch or maybe an IR detector. I am pretty new to circuits and am just starting to learn how to read schematics.
