Hi
I have used these 4 coil steppers in a auto tuned amplifier.
The really simple way is to use a BASIC Stamp with a ULN2803A motor
driver chip. Have a look at page 99 of the BASIC Stamp Programming
Manual 1.9 .
I used steppers salvaged from a fax machine.
All the driver pulses are generated in software which can then be
integrated with the rest of your control routines.
