I am using the ULN2003 two pin stepper setup from Manual 3 pg 15 for a unipolar stepper.
It uses power all the time because one winding is always powered.
I thought if I changed the output pins to input that it would be tristated and the motors would not be using power. Had it all worked out in the software then thought....oops I really don't know how this circuit works.
Will making both output pins into inputs acutally cause damage to anything? I really don't like the blue smoke thing at all.
