Step 3Figure out the Stepping Order
I was going to drive this motor as a bipolar one, so I'm ignoring the White ground wire. I've only got four wires to worry about.
You might want to run your unipolar motor as bipolar anyway, because it uses the whole coil in both phases instead of alternating between the two halves of each coil. More coil = more torque.
Run current through a pair (noting the polarity you chose) and then run current through the other pair at the same time. When you hook up the second pair, watch which way the motor turns. Write this down.
Now reverse the polarity on the first pair you chose. Then hook up the second pair again with their polarity also reversed. Note the direction.
From this you should be able to figure out the sequence for rotating the motor in either direction. In my example, both ended up turning counterclockwise, so stepping through the sequence in the same way I chose will step the motor CCW.
