Just a quick circuit I was working on and testing with an led before I finish it off with an rgb strip. I used the a 3.5 mm jack as my input and got the led to flash to whatever the input was. The problem in trying to solve right now is that if the volume is increased, the op amp cuts the signal and it also seems as if the led remains on all the time because of this. I was thinking of using the input signal to vary the gain of the op amp so that if the volume is increased, then the gain would somehow remain the same as it was before the volume change. Any ideas on how to do this or any other methods of achieving this? Also, I'll update a new circuit once I get this all working so that everyone can have a sound "viewing" rgb led strip 👍
