Motorized POT

[The Dark force of dance]

Y-ellow Y'all.
	I can get some little motorized pots. I had this crazy idea of putting one
on my mixer. I may well have enough resources (and code space) left to
drive it but I need to drive it as simply as possible. And! I don't have a
clue about driving motors.

I realize the theory is simple enough. You use the feedback from the pot to
report the position and then drive the motor till it reaches that position.
I'd assume that the motors on these pots would be a tiny servo but what is
the simplest way to drive them in both directions. I've also heard where
you really need a separate power supply for the servo 'n' stuff. The bottom
line is that if I can't do it with just a couple of transistors, using PWM
from the micro it's probably not worth doing. But if there's some way of
doing it then it becomes feasible.

Any help would be most appreciated.

Thanks in advance.

Be absolutely Icebox.
