I want to build a color organ that only changes color when it hears the bass from a song. I found an example on Make.com that had a color organ with low, mid and high-frequency( Easy LED Color Organ that Blinks 3 Colors | Make:) so I just cut out the high and mid filters to get the schematic I wanted. I then found a schematic for bass boost (http://www.circuitbasics.com/build-a-great-sounding-audio-amplifier-with-bass-boost-from-the-lm386/) with an amplifier and finally a digital potentiometer(https://www.instructables.com/id/Digital-Potentiometer-MCP41100-and-Arduino/). My plan was to have the audio go into the bass amplifier via audio jack then pass through the digital potentiometer to control the LED sensitivity to the music and finally through the color organ. I have attached the each of the schematics to this post and the final combined circuit. I wanted to verify that this configuration would work, as I have not done this before and do not know if I need additional components to stabilize the transition between one circuit to the next. The Arduino will just be used to power a separate LED strip (if I wanted to add to the project later) and to change the values of the digital pot. Would this combination work or am I missing something?
