I have a rotary encoder and I want to use the switch to stop the rest of my code running, essentially switching off what I have going on.

I have this

boolean running = true;

void setup() {
  pinMode(swPin, INPUT);
  digitalWrite(swPin, HIGH);;
}

void loop() {

  if(digitalRead(swPin) == LOW) {
    running = !running;
  }

  if(running) {
    ...
  }
}

When I enter the if statement catching the switch press running does become false and the rest of the code is stopped. However, once released running is becoming true again and the starts again.

I guess it is because the rotary encoder isn't fixed in the LOW state but I expected the running variable to be set to false and remain since it is declared outside of the loop().

Any guidance would be much appreciated!!
