Making statements based on opinion; back them up with references or personal experience. I am running the code below. i was wondering if i can create a emergency stop button in a void loop() with a lot of while nested without using #interrupt , but with goto done; maybe? The stop button ( s2) has to allow the whole board to return to its initial state . Terminating the process, or returning an exit code, doesn't make sense in this environment. Actually, in none of the above the Arduino 'stops', it just is doing endlessly nothing (well internally endlessly checking against the true condition which never changes). Jul 7, 2022 · Hi friends, I am trying to precisely stop the stepper motor after every 2 seconds of rotation, avoiding the loop cycle. Aug 11, 2013 · Hi all. [code][code]#include <Stepper.
