Lab 6. RGB 三色 LED

單色 LED 與三色 LED

共陰、共陽

Arduino 的類比腳位

三種顏色各別的範圍

程式：隨機亂數

接法不同、程式也相反

(本範例使用共陰)

random(小值, 大值)

範例程式 lab6

const int greenPin = 10; // 設定 greenPin 的 PWM 驅動腳位
const int redPin = 11; // 設定 redPin 的 PWM 驅動腳位
void setup() {
}
void loop() {
  int blueValue =0; // blueValue 為藍燈 PWM 驅動值,初值為 0
  int redValue = 0; // redValue 為紅燈 PWM 驅動值,初值為 0
  int greenValue = 0; // greenValue 為綠燈 PWM 驅動值,初值為 0
  for(redValue=1; redValue<=255; redValue+=1){ //紅色呼吸燈迴圈
    analogWrite(redPin, redValue);
    delay(10);
  }
  for(redValue=255; redValue>=0; redValue-=1){
