Friday the ninth.
To Jonathan and all,
The delay between steps that works the best is 22ms – I tried 5ms right
after I received your post and the motor just quivered a little. I have
tried several values for the delay between steps and I still get the same
action out of the motor. The exercise I am doing is the “2-2 phase 12-volt
unipolar stepper motor” from Parallax’s web site with one exception – I am
using a “Homework Board” so I used the 9-volt supply instead of coming up
with the 12-volts as specified in the instructions – maybe this is my
problem. The motor seems to do a little “two-step” when going in the
clockwise direction but steps “smartly” in the counter-clockwise direction.
Thanks for getting back…

I have been trying different delay times and such with a stepper motor that
would that would do a two-step when turning in the clockwise direction and
would function just fine in the counter-clockwise direction and the problem
went away. I still need a delay of around 22ms between each step for the
rotation to be “guaranteed” but I can live with that. Just thought that
someone would like to know what happened here.

So the problem just "went away", with no discernable cause? I hate that :-0
