I was at a line-following robot competition recently and one of the contestants mentioned that he tuned the IR detectors to match the emitters. I asked if he meant that he was pulsing the emitters, but he said no.
I know about tuning for a carrier frequency, like 38kHz, but had never heard of tuning for the light frequency. What was he doing?
