I am trying to get my PC speakers to be controlled by my arduino. I've taken apart the control and it seems very straight forward, just need a few questions about subbing the manual pots for digital ones.
Volume circuit looks like this (R/L for right and left channels)
R Aux -> Pot Leg 1 -> Out Pot Leg 3 -> R Audio Out L Aux -> Pot Leg 2 -> Out Pot Leg 4 -> L Audio Out
All other POT contacts are grounded and it's a B10K pot.
Why are these split by channel? Isn't a standard 3 terminal pot the same? Or is it to keep the audio in R and L channel's seperate?
Is there any weird issue I'll run into subbing out this pot for a digital one? Or would another 4/6 contact digital 10K pot do just fine? Are their power requirements (voltage/heat dissipation) i need to watch out for?
Thank you! Just learning speaker wiring.
