We're trying to build a circuit that will detect when a laser crosses a photoresistor and light an LED. What we're trying to do is have three different photoresistors, and three diffferent LED's, each of which correspond to one photoresistor. The idea is that when one photoresistor is struck by the laser, the corresponding LED will stay on. We were hoping to find an IC that would make the job a bit easier but we're new to this stuff and any pointers would be very much appreciated.
