Hi all,
I've got an old tabletop Pacman game that works fine but I want to add a volume control knob/slider to the game.
Internally, two wires connect from the PCB to a small metal disk, which vibrates to create sound. A thin plastic "cup" amplifies the sound while holding the disk in place.
What I *think* I need is logarithmic potentiometer, but I don't know what range (0 - 1k?) I should be looking for. Any thoughts?
