Controlling RGB LED using Arduino

In this page you will get the code to control RGB LED using Arduino

Image above shows the RGB LED has 3 LED in one package

Image above shows connecting resistor on Common-Cathode and Common-Anode

int RED = 11;// the PWM pin the RED LED is attached to

int colorTime = 2000; // time to wait between color change

int color[8][3] =
               {255,255,255},// white

void setup() {
   // Robojax.com RGB LED code 20181006
  // declare pin 11,12, 13 for RED , GREEN and BLUE to be an output:
  pinMode(RED, OUTPUT);
     digitalWrite(RED,LOW);// turn RED led off
  pinMode(GREEN, OUTPUT);
     digitalWrite(GREEN,LOW);// turn RED led off  
  pinMode(BLUE, OUTPUT);
     digitalWrite(BLUE,LOW);// turn RED led off  

// the loop routine runs over and over again forever:
void loop() {

  // Robojax.com RGB LED code 20181006

      for(int j=0; j<8; j++)
        RGB_LED(color[j][0], color[j][1], color[j][2]);
      delay(colorTime);// delay for each color

  sends correct value to R, G and B and LED pin
  @param r is received red value
  @param g is received green value
  @param b is received blue value
void RGB_LED(int r, int g, int b)
        analogWrite(RED, r);// set value for RED LED        
        analogWrite(GREEN, g);// set value for GREEN LED          
        analogWrite(BLUE, b);// set value for BLUE LED
