I've heard about the AccelStepper library, however that's not working either- although i may not have used it properly. Pressing the rotateMotorPin button again when the motor is in motion is supposed to increase the speed, however it doesn't do anything. it's supposed to keep going indefinitely until i press the stop button.

The motor stops moving after 1-2 revolutions. if i attempt to do so, the motor vibrates and makes a whining sound without moving at all. Going from setspeed(0) to the currVelocity by pressing the rotateMotorPin button does nothing I have a few problems since i'm new to this:

for now, velocity functions 2, 3 and 4 are not implemented, but it's largely the same as the velocity 1 function. i could make the motor stop as well with a different button (and then resume the previous speed with the other button). the switch statement checks the current state and calls a function accordingly.

i'm trying to make the motor go to a higher speed (that i specify) at each button press according to a switch statement. Hi, i'm having trouble with a 28byj-48 stepper motor on my elegoo uno r3.
