Simple Led strip with array issue

Other Hardware LEDs and Multiplexing

No it did not work with the code you supplied. I am not sure what you mean by image of the setup, it's literally just an arduno nano, with an LED strip cut down to 6 led's. Ground to ground, power to 5v, digital to pin 6.

Here is the code I updated...

#include "FastLED.h"
#include <EEPROM.h>
#define NUM_LEDS 6
CRGB leds[NUM_LEDS];
#define DATA_PIN 6


int Arry1[NUM_LEDS] = {0, 3};
int Arry2[NUM_LEDS] = {1, 4};
int Arry3[NUM_LEDS] = {2, 5};
int i = 0;


void setup()
{
  FastLED.addLeds<WS2811, DATA_PIN, GRB>(leds, NUM_LEDS).setCorrection( TypicalLEDStrip );
  FastLED.clear();
  Serial.begin(9600);
}
  
void loop(){

   FastLED.clear();
   delay(500);
   Ary1();

   delay(500);
   Ary2();

   delay(500);
   Ary3();
  }

 void Ary1(){
    FastLED.clear();
  for(int i = 0; i < 2; i++){
    leds[Arry1[i]] = CRGB::Red; 
     Serial.println(Arry1[i]); 
    FastLED.show();
 }
 }

void Ary2(){
  FastLED.clear();
  for(int i = 0; i < 4; i++){
    leds[Arry2[i]] = CRGB::Red; 
   Serial.println(Arry2[i]); 
    FastLED.show();
 }
}
 
 void Ary3(){
   FastLED.clear();
  for(int i = 0; i < 6; i++){
    leds[Arry3[i]] = CRGB::Red; 
  Serial.println(Arry3[i]); 
    FastLED.show();
 }
 }
