RGB LED模塊由一個插件全彩LED制成，通過R、G、B三個引腳的PWM電壓輸入可以調節三種基色（紅/藍/綠）的強度從而實現全彩的混色效果。用Arduino對模塊的控制可實現酷炫的燈光效果。
Arduino源程序如下:
- int redpin = 11; //select the pin for the red LED
- int bluepin =10; // select the pin for the blue LED
- int greenpin =9;// select the pin for the green LED
- int val;
- void setup() {
- pinMode(redpin, OUTPUT);
- pinMode(bluepin, OUTPUT);
- pinMode(greenpin, OUTPUT);
- Serial.begin(9600);
- }
- void loop()
- {
- for(val=255; val>0; val--)
- {
- analogWrite(11, val);
- analogWrite(10, 255-val);
- analogWrite(9, 128-val);
- delay(1);
- }
- for(val=0; val<255; val++)
- {
- analogWrite(11, val);
- analogWrite(10, 255-val);
- analogWrite(9, 128-val);
- delay(1);
- }
- Serial.println(val, DEC);
- }
