Had the best ever success tonight.

I built the Pulse Generator and it worked first crack. Then had the thought to test the output, via a speaker, that worked.

Ok, next step the stepper driver.

Unbelievable success.....The pulse generator powered the driver for the stepper and the stepper turned accordingly to the frequency.
It is a little bit dirty on it's operation, but the test was a little bit past expectation.
The power I was using was 12V with 300ma. Unsure if that was enough current, but it seemed to work fine.

The stepper drove fast and slow enough, but there was a slight issue with the graduations of it. It ramped up and down quite fast, it was a little hard to control the speed. The finite control was missing.

But all in all, I just didn't believe it to work. Pretty stoked.

Now to modify the smoothness of it.
Also not sure how to get "reverse" yet, it's seeming to show a double pulse to turn it in reverse. I won't do that for a bit, as changing speed in one direction is ok, as long as the object is moving.
