This is a newbie question:
I need to drive a stepper moter (14HS11-1004S here: Moteur 14HS11-1004S - Moteurs pas-à-pas | GO TRONIC)
the vendor advise to use the Polulu A4988 driver module.
Then begin the fog for me.
Polulu web site list this library :GitHub - laurb9/StepperDriver: Arduino library for A4988, DRV8825, DRV8834, DRV8880 and generic tw
That is obviously very unclear. poor documentation.
And I found this one as an alternative:
looking more friendly.
Any suggestions please ?
My need is to make the stepper turning constantly a speed defined by a potentiometer position (the potentiometer will be read on a A pin or the UNO, then a value must be sent to the driver to set the rotation speed.
a Stop/Go button (one impulsion we change the state rotate or stop it) must be added too.
How can I do this please.
