Short question:
I want to drive a fourphase 12V stepper motor from a 5V HCT latch.
Is it possible to use a simple NPN transistor and to connect
the motor common lead to 12V instaed of ground ?

Will the stepper run with reversed coils ?
I'll try out but I'd like to know if I do big big NONO's :-)


Thanks in advance, Bjoern
