A4988, it's really easy you just need to feed some pulses into the "step" input. Depending on whether "dir" input is high or low it'll turn cw or ccw, and every pulse on "step" will make the motor turn one step (or microstep depending on what you set it to) I'll put the code for my potentiometer speed control in the description of the next video, but for now here's the how-to article I always use as reference: www.makerguides.com/a4988-stepper-motor-driver-arduino-tutorial/

What kind of stepper motor are you using? I have been looking into unipolar steppers but cant find any that have a RPM like this

This one was salvaged from an old Canon flatbed scanner, it's bipolar and I was very surprised to find it has 200 steps/revolution... Yeah the unipolar ones seem to have a much tighter speed range they can be used at, but depending on the application I think they can be made to work anyway via some physical accommodations
