More info at my blog: http://dmt195.wordpress.com. This video shows 2 Picaxe microcontrollers. One is a stepper motor controller that takes serial commands and then rotates the stepper motor by the appropriate number of steps at the specified speed. The red LED lights up to say that the move is complete and the circuit is ready for the next command. The second picaxe chip just supplies serial commands based on the state of the potentiometer.

  • @Duxasblt A stepper motor hasn't really got a + and -

    It features (in your case) 4 coils, you'll have to apply voltage in sequence to them to make it turn.

    A very simple 555 and 4017 circuit can do that

  • nice one

    say how do you know + and - wires? i found stepper motors in my garage a few days ago theyre working but i cant figure out the voltage and the wires, can you halp me?here are wires:
