Multi loops after time

Using Arduino Programming Questions
#1

Hello,
i want my Diggi Keyboard to constantly use the keys F1-F4, this is no problem for me to do.
But i want that the F9 key will be pressed after 10 minutes and this all in should be in loop, so i have 2 loops running at the same time with 2 diffrent events.
Could some help me please? :confused:

Yes, show your code.... See How to use the forum please.

#3 
#include "DigiKeyboard.h"

void setup() {
}


void loop() {              

  DigiKeyboard.sendKeyStroke(KEY_F1);       //pressing F1-F4
  DigiKeyboard.delay(500);
  DigiKeyboard.sendKeyStroke(KEY_F2);
  DigiKeyboard.delay(500);
  DigiKeyboard.sendKeyStroke(KEY_F3);
  DigiKeyboard.delay(500);
  DigiKeyboard.sendKeyStroke(KEY_F4);
  DigiKeyboard.delay(500);
  }

  void loopF9() {

  DigiKeyboard.sendKeyStroke(KEY_F9);      //using F9 
  DigiKeyboard.delay(600000);              //delay of 10 minutes
  }

this is my code, i know that 2 void loop() dont work.
I want the first loop to be sapmmed constan and the loopF9 to be used evrey 10 minutes.

When delay() is running, nothing else can happen. You can use the trick from the example "BlinkWithoutDelay" to do things at a timed interval.

#include "DigiKeyboard.h"


void setup()
{
}




void loop()
{
  static unsigned long startTime = 0;
  
  DigiKeyboard.sendKeyStroke(KEY_F1);       //pressing F1-F4
  DigiKeyboard.delay(500);
  DigiKeyboard.sendKeyStroke(KEY_F2);
  DigiKeyboard.delay(500);
  DigiKeyboard.sendKeyStroke(KEY_F3);
  DigiKeyboard.delay(500);
  DigiKeyboard.sendKeyStroke(KEY_F4);
  DigiKeyboard.delay(500);


  if (millis() - startTime >= 600000UL)  //every 10 minutes
  {
    startTime += 600000UL;
    DigiKeyboard.sendKeyStroke(KEY_F9);      //using F9
  }
}

  {
    startTime += 600000UL;
    DigiKeyboard.sendKeyStroke(KEY_F9);      //using F9
  }
}

to change the time to use F9 i just have to change if (millis() - startTime >= 600000UL) and startTime += 600000UL;.
is this right so i want to happen evrey 5 minutes i change both 600000 values to 300000?

#7

You changed the delay of F9, but the other F stuff is still blocking...

Yes. If you think you might want to do this more than once you should declare a constant so you only have to change it in one place.

const unsigned long F9Interval = 10UL * 60UL * 1000UL;  // 10 Minutes
void loop()
{
  static unsigned long startTime = 0;
  
  DigiKeyboard.sendKeyStroke(KEY_F1);       //pressing F1-F4
  DigiKeyboard.delay(500);
  DigiKeyboard.sendKeyStroke(KEY_F2);
  DigiKeyboard.delay(500);
  DigiKeyboard.sendKeyStroke(KEY_F3);
  DigiKeyboard.delay(500);
  DigiKeyboard.sendKeyStroke(KEY_F4);
  DigiKeyboard.delay(500);


  if (millis() - startTime >= F9Interval)  // every interval
  {
    startTime += F9Interval;
    DigiKeyboard.sendKeyStroke(KEY_F9);      //using F9
  }
}

What if i want to make more then 2 loop´s?

#include "DigiKeyboard.h"


void setup()
{
}




void loop()
{
  static unsigned long startTime = 0;
  
  DigiKeyboard.sendKeyStroke(KEY_F1);       //pressing F1-F4
  DigiKeyboard.delay(250);
  DigiKeyboard.sendKeyStroke(KEY_F2);
  DigiKeyboard.delay(250);
  DigiKeyboard.sendKeyStroke(KEY_F3);
  DigiKeyboard.delay(250);
  DigiKeyboard.sendKeyStroke(KEY_F4);
  DigiKeyboard.delay(250);

     if (millis() - startTime >= 240000UL)  
  {
    startTime += 240000UL;
    DigiKeyboard.sendKeyStroke(KEY_F9);      //using F9
  }
  if (millis() - startTime >= 1140000UL)  
  {
    startTime += 1140000UL;
    DigiKeyboard.sendKeyStroke(KEY_F12);      //using F12
  }
 
}

i would use the last const too but what if i want F9 evrey x seconds and F12 evrey y seconds?

#10

Use a separate start time variable for each timer.

#11

so should it work like in my code at the last post?

No. Like I said: "Use a separate start time variable for each timer." If they share a start time, only the shortest interval will trigger and that reset the start time. The longer intervals will never trigger. That is why, like I said, "Use a separate start time variable for each timer."
