Thank you so much for making a video on this!! It was super helpful for me while choosing steppers for a project.

Thanks for your video. You mention that you use your own code instead of the standard libraries. Could you please elaborate on this code? I managed only 14 rpm using the digitalwrite to the four pins. (0, 0, 0, 1 -> 0, 0, 1, 0 -> 0, 1, 0, 0 -> 1, 0, 0, 0). And a delay(2) after that as delay(1) does not seem to work. I would be very interested in hearing how you managed to get up to 25 rpm!

Thank you in advance!
