I have been drawing out specs for a light and fan control panel and have finally reached a problem. Is there a way to use two buttons (up and down) to take the place of a knob/dial for a rheostat? If possible, I would rather not have to use a motor as that would take more space, and I want to keep this as small as I can.
Here is a (badly drawn) schematic of what I want:
Thanks for any help in advance.
