Robin2:
How many steps per second will the motor be required to make?
I presume the thing it is moving will not have enough momentum to make the motor miss steps when a change of direction is required? Or do you plan to use acceleration and deceleration to deal with that?Thanks Mark for the correction about the ULN2003.

Okay, I'll buy the driver given in reply 6, the Adafruit.
The brochure I gave above for the Nidec says step size is 18 degrees. I think this is a typo. Isn't 1.8 degree more common? I'll probably shoot for something like 30 steps per second to start with.
It's not a precision application so missing steps is not a big deal. Yes, the attachment it's moving has very little momentum.
I think I'm going to spend the next couple of days doing some reading first with all the resources out there so I can come back with more intelligent questions. In the meantime, feel free to comment or give advice.
thanks
