    Help

    Anybody help...
    We have this school project, we are making a electric fan controlled by PIC16F84A then goes through a stepper motor ..
    Anybody can give me a program that can be controlled by switches for the rotation of the stepper motor. For example (Sw - Switch) Sw1 is 45 degrees , Sw2 90 degrees, Sw3 180 degrees, and Sw4 360 degrees..
    Can anybody lend some circuit diag. or configurations on how to construct this. My stepper motor has 5 pins.

    Thnx

    ucn5804B is a good alternative and completely logic based chip for controlling unipolar stepper motors, it s easier and more expensive way than ULNs..

    Stepper via parallel

    I have also controlled the stepper motor via parallel port using matlab.
    Also that was a uni polar stepper motor and they are much easier to control.
    One can make a very nice simple graphical interface in matlab and directly by clicking on buttons one can control the stepper in any way.
    This really is a cool way to play with steppers.
