Hello
I want to make a counter using a laser emitter and receiver.For the receiver i have used photoresistance but it was not a good solution because this receiver is very sensitive to the ambient light.Can you propose to me a suitable laser detector that can ot be affected by the interference with the ambient light emitted by the lamp.
Thanks
Can't be done. The work-around is to modulate the laser signal and then have the receiver detect the modulation.
Look at how your IR remote control works. Same principal.
