step motor arm7

helo..
im doin a projcet on embedded web cam server..v r usin ATEB9200 ARM board.A webcam is connectted to the USB port of the ARM board. A stepper motor connected to the I/O pins of the ARM board controls the rotation of the webcam.

Can anyone please help me with the details as how to connect the stepper motor to the ARM and its driving circuitry?
 

interfacing gpio motor

Whatever be the kind of stepper motor, put a driver (darlington array like ULN2803 for unipolar and HBridge for bipolar) and interface GPIO of ARM.

This assumes you have the driving logic right.
