While loop crashing IOT 33

[Abyssalfield]

I have my code running in a loop for main but I want to add a while loop so I can "pause" the program when a switch is flipped on the cloud dashboard.

This works:

void loop() {
  ArduinoCloud.update();
  // Your code here
   
    if (i < 10)
    {
      i++;
      humidity = i;
    }
    if (i > 9)
    {
      i = 0 ;
      humidity = i;
    }
    if (temp > 75)
    {
      temp = 0;
    }
  }

This does not work:

void loop() {
  ArduinoCloud.update();
  // Your code here
   while (cycleRunning){
    if (i < 10)
    {
      i++;
      humidity = i;
    }
    if (i > 9)
    {
      i = 0 ;
      humidity = i;
    }
    if (temp > 75)
    {
      temp = 0;
    }
  }
}

cycleRunning is a bool
The only change is the while loop. The only thing outside of main is the auto generated variables for accessing the cloud. I have already read this thread. Any Ideas?

add a while loop so I can "pause" the program when a switch is flipped on

Before the last "}" matching the loop() "{" add

do {
} while (condition);

In your case, select a free digital pin.
Make the pin an input.
Turn on the pullup.

Ex:

const int buttonPin = 2;     // switch pin BEFORE setup()

 pinMode(buttonPin, INPUT_PULLUP);   //  added to setup()

Now:

do {
     delay(1);
} while ( ! buttonPin) ;

When the switch is OPEN, the code will run, when the switch is CLOSED, the code will temporarily hang.

void loop() {
  ArduinoCloud.update();
  // Your code here
   if (cycleRunning) {
    if (i < 10)  {
      i++;
      humidity = i;
    }
    if (i > 9)   {
      i = 0 ;
      humidity = i;
    }
    if (temp > 75)  {
      temp = 0;
    }
  }
}

Assuming the value of cycleRunning is set elsewhere...
simply change the while to an if()
