A couple of additional notes - I would like the controller to be able to drive the motor in either direction (selectable) as well as include a momentary button/input that would run the motor at a much higher speed in order to set the clock.
hi,
I need a (what I assume is) fairly simple circuit that can drive a small stepper motor. By small, I mean something like this:

400mA @ 12V max.
This would be placed in a clock, so it would need to use a crystal/oscillator of some sort to keep...
