I try to connect 3 RGB LED to my Arduino Nano ESP32

Projects Programming
7

This is the code I used for only one RGB LED

on this code I added the other 2 LEDs
(e.g. r_pin1, r_pin2, r_pin3 and r_val1++, etc...)

int r_pin = 12;
int g_pin = 11;
int b_pin = 10;

int r_val = 0;
int g_val = 255;
int b_val = 255;

void setup() {

  pinMode(r_pin,OUTPUT);
  pinMode(g_pin,OUTPUT);
  pinMode(b_pin,OUTPUT);

}

void loop() {

  while (r_val != 255)
    {
      analogWrite(r_pin,r_val);
      analogWrite(g_pin,g_val);

      r_val++;
      g_val--;

     delay(10);
    }

      while (g_val != 255)
    {
      analogWrite(g_pin,g_val);
      analogWrite(b_pin,b_val);

      g_val++;
      b_val--;

      delay(10);
    }

      while (b_val != 255)
    {
      analogWrite(b_pin,b_val);
      analogWrite(r_pin,r_val);

      b_val++;
      r_val--;

      delay(10);
    }
}
