Hi, I've recently started using Arduino for implementation in simple projects. I have now a NEMA17 stepper connected to a Pololu A4988 driver circuit and find various code to use it with a simple Arduino Pro Mini 3V3/8MHz. So far so good. However, I would like simply to run that stepper motor in t…

Have you set the coil current limit on the A4988 stepper driver. It is important that it be properly set for longevity of the motor and driver and best performance. Here is a demo program to show how to run a stepper at a constant speed and also monitor a switch. Pressing the switch will read a p…
