Hey everyone, I have the code below which is used to turn a stepper motor in forward or reverse a certain number of steps depending on which of the two buttons is pushed. To activate forward or reverse, the button must be pressed and released. Is there a simple way to change this code so that the motor will continue to turn in forward or reverse for as long as the button is pressed? This is opposed to just turned the defined number of steps per the code. If anyone has any similar code to reference that would be much appreciated. Thanks!
