Very newbie question so my apologies!
I just picked up an Alps Alpine motorized Potentiometer (100k) for a preamp board I’m working on, but I’m curious how I actually go about incorporating a remote to control the volume pot?
I’ve seen a few PCBs (both digital pots and ones that physically move a motorized pot) on Aliexpress but curious if there are any better options out there
And suggestions or pointers are very appreciated!
Thanks 🙂

Driving the motor is pretty easy. A MOSFET H-bridge will do it. The hard(er) part is the remote control. Personally I'd write some micro controller code to interpret Philips RC-5 or the NEC protocol used by the Apple Remote. You may also be able to find a remote+receiver combo that'll give you UP and DOWN signals for controlling the H-bridge.
