neksmerj:
I found this tutorial re Arduino and EasyDriver employing 3 push buttons for forward, stop and reverse plus potentiometer for speed on the fly. Included also is a schematic diagram.
I'm delighted you have found something that works for you.
But, to be honest, I don't understand how the link you gave is any different from the combination of my code and the diagram on the Pololu A4988 page.
And I guess my frustration has been my inability to find the key that would help me to bridge whatever gap exists between what I write and your understanding of what I write. I suppose I expect people who don't understand to respond with lots of questions that illustrate that gap - and you will have noticed from earlier posts that for a long time I was not even sure if you had read my stuff.
