RGB LED

單顆RGB LED有四隻腳：R、G、B、GND

程式碼

const int Red = 9;

const int Green = 10;

const int Blue = 11;

void setup() {

pinMode(Red, OUTPUT);

pinMode(Green, OUTPUT);

pinMode(Blue, OUTPUT);

}

void loop() {

analogWrite(Red,255);

analogWrite(Green,0);

analogWrite(Blue,0);

delay(1000);

analogWrite(Red,0);

analogWrite(Green,255);

analogWrite(Blue,0);

delay(1000);

analogWrite(Red,0);

analogWrite(Green,0);

analogWrite(Blue,255);

delay(1000);

}

利用迴圈由0開始遞增R、G、B三個變數值。

0 > 紅 > 紫(紅+藍) > 藍(紅遞減) > 黃(藍+綠) > 綠(藍遞減) > 黃(綠+紅) > 紅(綠遞減) > 0
