why does a diode laser switch off a light emitting diode.?
It's a series of 8 led round a webcam for light however I used a button battery and connected a single led and it was switched in the same way.
The lazer is a pointer as you may have guessed the led a white light led and it switched depending on the angle of the lazer beam.
We need more information - like the way they are wired-up...
