Arduino 蜂鳴器與喇叭

因應他人需求所以做了這樣的一個Demo, 歌曲資訊來自網路
簡單的蜂鳴器接線圖、以及喇叭的

void setup(){
  pinMode(22,OUTPUT);
}
void loop(){
  digitalWrite(22,HIGH);
      delay(1);
      digitalWrite(22,LOW)
      delay(1);
}

另外,delay還有多種形式，像是:

delayMicroseconds();//千分微秒
millis();
micros();

另外可以使用本項器材彈出音樂:
首先寫入由網路上找的前置處理標籤:
