Al was kind enough to post a question from me about sharing pins on an Arduino (in the main blog for 13th March). I had several useful replies, so thanks to everyone involved.
Lou mentioned the large number on non-PWM pins on the board I am using (a Mega). This made me think of a very basic question:
"Can stepper motors be fed their control signals via the digital pins rather than PWM pins?"
I had been assuming that you had to use PWM pins, which are limited in number. Mainly because every example I had found on the web was using 4 PWM pins to drive the stepper. The tutorial document which came with my Elegoo starter kit also mentioned PWM pins for its stepper motor example.
