CODE COMBINING, WANT TO COMBINE CODE A AND B TOGETHER FOR MORE PATTERNS IN ONE STRIP. REQUEST GUIDANCE.

CODE A IS WORKING PERFECTLY ONE AFTER ANOTHER BUT IN CODE B  WORKING ONLY UP TO

REQUEST INSTRUCTIONS TO COMBINE BOTH A AND B TOGETHER. THANKS.

Hi Jayanath,

I really don't want to sound rude, but you should really pay more attention to netiquette.

Writing in all capital characters is considered shouting, and commonly seen as rude.
I know this is probably not what you intend to do.

Second of all, if you post code;

1) Make sure you do this in the appropriate place,
2) If you post the code, make sure it is formatted as such (select the code and press the "code" formatting button),
3) I'd recommend posting your code as two separate attachments, instead of pasting a long and unformatted piece of code.

Since I don't know what you have tried so far;
If the posted code is what you've been trying, then I can only say that combining code this way will never work.

For one the start section of the code (with the includes and the #define's and such) can appear only once.
The functions void setup() and void loop() can appear only once as well.

Dear sir, i understood. Sorry Again. Below is the my code. The problem is Case 0: is not functioning only just flash once and starting from case 1:.

Looks like that is what you've told it to do.

In your code, you've placed the change of the selectedEffect in the loop(). Meaning; it will run this over and over again.
So your code increases the selectedEffect, runs one effect once, and then starts the loop again (increase effect, run effect).

So when your Arduino starts, it will run effect 1, effect 2 ,... last effect, and then reset to effect 0, and continue again with effect 1, effect 2 ,... last effect.

The bold part of the code:

void loop() {
   static uint8_t startIndex = 0;
    startIndex = startIndex + 1; /* motion speed */
    FillLEDsFromPaletteColors( startIndex);
    FastLED.show();
    FastLED.delay(1000 / UPDATES_PER_SECOND);
  selectedEffect++;
  if(selectedEffect>12) {
    selectedEffect=0;

  }
  switch(selectedEffect) {
    case 0 : {
                ChangePalettePeriodically();
                break;
              }

1) This code make it start with effect 1 (and not 0).

A few changes would make it start actually at zero.
In the beginning of your code, you see:

byte selectedEffect=0;

Replace this with

byte selectedEffect=250; // arbitrary value

With this, the bold code, will reset selectedEffect to zero, and your loop will indeed start with effect zero.

2) I have no idea what the function "ChangePalettePeriodically()" does. It seems to do nothing (effectwise).
I suspect it works with the "FillLEDsFromPaletteColors()" function.

In your new code, I see the same function defined twice?

...
 void FillLEDsFromPaletteColors( uint8_t colorIndex)
{
    uint8_t brightness = 255;
    
    for( int i = 0; i < NUM_LEDS; i++) {
        leds = ColorFromPalette( currentPalette, colorIndex, brightness, currentBlending);
        colorIndex += 3;
    }
}
void FillLEDsFromPaletteColors()
{
    uint8_t secondHand = (millis() / 1000) % 60;
    static uint8_t lastSecond = 99;
...

This is probably not a good thing ... not saying it will resolve the issue, but it's not the way it should be ...

dear sir thanks for the early reply. below i posted original second code and this is well working. request instructions to combine with yours ' case ' code.

#include <FastLED.h>
#define LED_PIN 5
#define NUM_LEDS 150
#define BRIGHTNESS 255
#define LED_TYPE WS2811
