I'd like to replace two volume push buttons on a bluetooth amplifier with a potentiometer. I'm not 100% sure how the push buttons are working at the moment, but a quick connectivity test shows they're running to a bank of small resistors, so I'm guessing a pulse is sent to a microcontroller to tell it to digitally select a new voltage. I'll attach a pic.
Is there any way to convert this to a potentiometer? Or would I have to do that at another point (perhaps the output of the IC)?
