Problems with Switch Case Statement

I have recently replaced my original forum post with this one. Specifically, my problem is narrowed down to Switch Case statements. I want to control 5 led frequencies using poteniometers. Each one needs to be independently controlled and running from each other.

// Which pins are connected to which LED
const byte greenLED = 12;
const byte redLED = 13;

// Time periods of blinks in milliseconds (1000 to a second).
const unsigned long greenLEDinterval = 500;
const unsigned long redLEDinterval = 1000;

// Variable holding the timer value so far. One for each "Timer"
unsigned long greenLEDtimer;
unsigned long redLEDtimer;

void setup () 
  {
  pinMode (greenLED, OUTPUT);
  pinMode (redLED, OUTPUT);
  greenLEDtimer = millis ();
  redLEDtimer = millis ();
  }  // end of setup

void toggleGreenLED ()
  {
   if (digitalRead (greenLED) == LOW)
      digitalWrite (greenLED, HIGH);
   else
      digitalWrite (greenLED, LOW);

  // remember when we toggled it
  greenLEDtimer = millis ();  
  }  // end of toggleGreenLED

void toggleRedLED ()
  {
   if (digitalRead (redLED) == LOW)
      digitalWrite (redLED, HIGH);
   else
      digitalWrite (redLED, LOW);

  // remember when we toggled it
  redLEDtimer = millis ();  
  }  // end of toggleRedLED

void loop ()
  {

  // Handling the blink of one LED.
  if ( (millis () - greenLEDtimer) >= greenLEDinterval)
     toggleGreenLED ();

  // The other LED is controlled the same way. Repeat for more LEDs
  if ( (millis () - redLEDtimer) >= redLEDinterval) 
    toggleRedLED ();

/* Other code that needs to execute goes here.
   It will be called many thousand times per second because the above code
   does not wait for the LED blink interval to finish. */

}  // end of loop

This is my working revised version of the code:

///Output 1 
int pot1 = A1;
const int out1 = 22;
int potVal1 = 0;
int frequency1 = 0;
int enable1 = 28;

//Output 2
int pot2 = A2;
const int out2 = 23;
int potVal2 = 0;
int frequency2 = 0;
int enable2 = 29;

int pot3 = A3;
const int out3 = 24;
int potVal3 = 0;
int frequency3 = 0;
int enable3 = 30;

int pot4 = A4;
const int out4 = 25;
int potVal4 = 0;
int frequency4 = 0;
int enable4 = 31;

int pot5 = A5;
const int out5 = 26;
int potVal5 = 0;
int frequency5 = 0;
int enable5 = 32;

}  // end of loop

This code also works exactly how I want it to, but I want each case to incrementally include the handling of each LED blinking. For example, for case 1, frequency 1. For case 2, frequency 1 and 2. For case 3, frequency 1, 2, 3. The code for the handling of this is below. When run, the LED's flash, but I cannot change the frequency with the potiometers like in the code above. I'm sure I'm making a silly novice mistake.

 switch(attention / 10) {
            
    case 0:
   
      potVal1 = analogRead(pot1);
      frequency1 = map(potVal1, 0, 1023, 15, 500);     
      //Serial.println(frequency1);
      const unsigned long output1interval = frequency1;

      if ( (millis () - output1timer) >= output1interval)
      Output1 ();
      
   break;
       
       
   case 1:
   
     potVal1 = analogRead(pot1);
      frequency1 = map(potVal1, 0, 1023, 15, 500);     
      //Serial.println(frequency1);
      const unsigned long output1interval = frequency1;

      if ( (millis () - output1timer) >= output1interval)
      Output1 ();


      potVal2 = analogRead(pot2);
      frequency2 = map(potVal2, 0, 1023, 15, 500);    
      //Serial.println(frequency2);
      const unsigned long output2interval = frequency2;

      if ( (millis () - output2timer) >= output2interval) 
      Output2 ();

   break;
   
            
   case 2:
     
      potVal1 = analogRead(pot1);
      frequency1 = map(potVal1, 0, 1023, 15, 500);     
      //Serial.println(frequency1);
      const unsigned long output1interval = frequency1;

      if ( (millis () - output1timer) >= output1interval)
      Output1 ();


      potVal2 = analogRead(pot2);
      frequency2 = map(potVal2, 0, 1023, 15, 500);    
      //Serial.println(frequency2);
      const unsigned long output2interval = frequency2;

      if ( (millis () - output2timer) >= output2interval) 
      Output2 ();
    
        
      potVal3 = analogRead(pot3);
      frequency3 = map(potVal3, 0, 1023, 15, 500);     
      //Serial.println(frequency3);
      const unsigned long output3interval = frequency3;
    
      if ( (millis () - output3timer) >= output3interval) 
      Output3 ();
      
   break;
 }

These frequency functions are added incrementally through 5

However, the potentiometer values do not influence the frequencies like intended. please help.

Do you know what the potentiometer values are? How do you expect the potentiometer to influence the frequencies (of what?)? How do the potentiometer values actually influence the frequencies?

The potentiometer values are mapped to a the values 20, and 500.

Once more, in English this time, please. Google doesn't seem to be able to translate this to anything I can understand.

These values turn in to millisecond values for a frequency range of 1-50hz.

The way you expect?

The code I am trying to split up into the cases originated from this helpful website.

While I expect that the site has useful information (Nick's sites usually do), that doesn't say anything about what you expect to see happen nor does it say anything about what actually happens.

      //Serial.println(frequency1);

Commented out Serial.print() statements are useless. Quit guessing what your code is doing, and start printing stuff (with identification strings, so you know WHAT you are printing).

Thank you, Paul.

Unfortunately the OP cannot upload his code, as he has privately informed me, because the Arduino forum's disk is full.

Sadly, although we have reported that problem it has not been resolved. It must be a fairly complex issue.

Unfortunately it is hard to help you when the forum is working so badly. Sorry about that.
