RGB module is a kind of integrated red, green, blue three basic color LED (Light Emitting Diode) module, composed of red, green and blue three independent lamp beads, common has four pins, a public port and three color control ports. We can control the red, green and blue three independent lamp beads separately through the control port, so as to realize the light mixing effect and produce a variety of different color effects.

4.Sample Code
1//Set the RGB pin
2int redpin=5;
3int bluepin=3;
4int greenpin=4;
5int val;
6void setup(){
7 pinMode(redpin,OUTPUT);
8 pinMode(bluepin,OUTPUT);
9 pinMode(greenpin,OUTPUT);
10}
11void loop()
12{
13 for(val=255;val>0;val--){
14 analogWrite(4,val);
15 analogWrite(5,255-val);
16 analogWrite(3,128-val);
17 delay(1);
18 }
19 for(val=0;val<255;val++){
20 analogWrite(4,val);
21 analogWrite(5,255-val);
22 analogWrite(3,128-val);
23 delay(1);
24 }
25}
5.Test Result
After the code is uploaded to the controller board, the RGB light will light up and the display light color will change in the order of cyan and pink.
