The purpose of the program is to rotate the stepper motor for a specific LDR measurement value if the button (TIA1HUA) is not pressed. Similarly, it will have reverse rotation for the remaining LDR measurement values with the limit of another button press. What happens is: that the rotation is done as intended, but when the button is pressed the rotation stops and does not start again. I am surprised that the text (that supposed to be printed from line in Bold form) is not even printed before the command that stops the motor (see the serial monitor output below).

This is what I'm getting from the serial monitor:
sensorMax = 460
19:08:20.463 -> sensorMin = 450
19:08:20.497 -> average = 455
19:08:25.969 -> Analog Lesung = 459
19:08:31.957 -> Going up = 441
19:08:37.984 -> Going down = 450
19:08:43.978 -> Going down = 439
19:08:49.973 -> Going down = 464
19:08:50.482 -> Analog Lesung = 462
19:08:56.489 -> Going up = 463
19:09:02.501 -> Going up = 465
19:09:08.501 -> Bu
Thank you very much for your help!!!
