Hello... I created a very simple set-up but for some reason I can't get it to work.
I have an IR LED that outputs a continuos 38kHz signal (LED is on and pulsates at 38kHz). I then have a normal LED hooked up to an IR sensor. Since the sensor receives a continuos 38kHz signal, I would expect this LED to be on continuously. Unfortunately this is not the case. For some reason it only turns on (flashes) when the sensor receives a "intermitted" 38kHz signal, as when for example a remote control code is transmitted.
My questions: What might be the issue here, and how can I get the LED to light up continuously in the presence of a continuos 38kHz signal?
