Hi every one
iwant to ask about the control of a stepper motor throug the parallel port,iwant to know can iuse uln2803 with the l297 to control the unipolar motor and if it could ,would you show me the schematic draw for it.
thanks in advance.
Connect the parallel port to the L297 inputs. The L297 outputs go to the ULN2803 inputs. The ULN2803 outputs go to the ends of the unipolar coils, and the center taps go to the power source.
I have a stepper motor driver circuit which i shown in the attachment. I need to control only one motor at a time. I used MoSFET for switch on or off of motor power. But problem is im using 12V motor, i need to drive the mosfet wiht TTL Logic, but its not working. Please suggest me the proper switching circuit to run only one motor .
