Hi,
I am trying to use the analog light sensor to build a laser obstacle course: A laser is pointed at the light sensor, when the laser beam is interrupted, a sound is played. My problem is: The measurement difference between when the laser meets the LDR and when it doesn’t is almost non-existent, even if the rest of the room is dark. (About 120-220 with laser and 80-180 without), so the difference cannot be detected. AM I missing something? Is the light sensor not suited to measure a laser beam? Am I doing something wrong?
All help is greatly appreciated!
Jakob
