I've attached a gif containing a schematic of the transistor circuit we use to drive each stepper coil. You will need to use 4 of these for each motor, and somehow arrange to energise them in the correct sequence to achieve full or half stepping of the motor. If the mailing list does not let the attachment through, I'll send you it separately. Cheers -- Phil Driscoll |
