    Hi everyone! I'm new here and getting back into circuits. I'm working on an LED light organ. I attached the schematic, it's pretty simple. It hooks up to a 3.5mm audio input and flashes some LEDs when the bass in the song hits. I'm using LED strips from this website here for my lighting

    You can see the schematic here

    So, thanks to help here on the forum I've got it working. The only problem is, it only works if the volume is set at a certain level. If the volume is too high, the lights are always on, if it's too low, the lights never come on. I'd like the circuit to work no matter what the level of audio. Does anyone have suggestions on how I might do this?
