RGB LED MODULE

Easy to connect, with only four cables. You can pin the module on the breadboard and use the male to male jumper cables, or use the male to female jumper cables to connect the module directly to the Arduino-compatible board.

Connect the – pin to the GND pin on your Arduino-compatible board. For our example, connect B (blue anode) to digital 9, G (green anode) to digital 10 and R (red anode) to digital 11 on your Arduino-compatible board.

const int redPin = 11;
const int greenPin = 10;
const int bluePin = 9;
 
void setup() {
  // Start off with the LED off.
  setColourRgb(0,0,0);
}
 
void loop() {
  unsigned int rgbColour[3];
 
  // Start off with red.
  rgbColour[0] = 255;
  rgbColour[1] = 0;
  rgbColour[2] = 0;  
 
  // Choose the colours to increment and decrement.
  for (int decColour = 0; decColour < 3; decColour += 1) {
    int incColour = decColour == 2 ? 0 : decColour + 1;
 
    // cross-fade the two colours.
    for(int i = 0; i < 255; i += 1) {
      rgbColour[decColour] -= 1;
      rgbColour[incColour] += 1;
       
      setColourRgb(rgbColour[0], rgbColour[1], rgbColour[2]);
      delay(5);
    }
  }
}
 
void setColourRgb(unsigned int red, unsigned int green, unsigned int blue) {
  analogWrite(redPin, red);
  analogWrite(greenPin, green);
  analogWrite(bluePin, blue);
 }

1. In this example we are connecting:
   Arduino   RGB LED
   D11    —    R
   D10    —   G
   D9     —    B
   GND —    –
2. Download and install the Arduino environment from here or use the web editor.
3. Download the sketch here and open or open the Arduino environment and copy the code into a blank sketch.
4. Connect your board to your computer with the included usb cable.
5. Select your board in Tools/Board/Arduino Uno.
6. Select your port in Tools/Port/COM#(Arduino Uno), this will change slightly depending on your operating system.
7. Upload pressing the arrow in the circle on the upper left.
8. You should see the RGB LED changing colors.
   That’s it!
