How can I trigger an LED sign to turn on when an object is tossed into a bucket? Answered
I am designing a bucket with a small LED sign on it, and I want the sign to light up when people successfully hit a target in the back of the bucket. Everything has to run on battery power, and the entire product has to be mounted on a pole (which will be held in hand).
I have considered motion sensors (Parallax PIR) and some sort of laser trip-wire (as one would find on a garage door system), but I am not sure how to implement either.
I have also looked into shock sensors, the kind used on some window and door security devices, however, I am not sure that the objects being thrown would be able to provide the shock needed (think toy cars, beaded necklaces and other small novelty toys).
The sign will consist of up to 200 LEDS, and it would be nice to have it stay lit for a second or two before turning off again.
