Hello, I have found from experiment that most LEDs, including UV and IR, can be used in reverse to detect the range of frequencies they are designed to emit.
I would like to make a simple detector using a transistor amplifier to drive a meter. Can I use one of these FET static detectors amplifiers and connect the LED cathode to the Gate instead?
