3-2 警告蜂鳴器

    汙染嚴重,感測值>200 ug/m3 時,發出警告蜂鳴聲,利用Arduino Digital 接腳 13 來控制蜂鳴器發聲。

    蜂鳴器接在13腳位,也會有特別效果,在插電或一些動作時,13腳位預設接到Arduino板上的LED,會有一些操作提示燈號,因此接了蜂鳴器就會發出一些提示聲。

需要材料:

    蜂鳴器(有源)  * 1

    短杜邦線  * 1

    麵包板跳線 黃色 * 1

 

測試程式:buzzer_test.ino、pitches.h  (兩檔案須放在同一資料夾)

buzzer_test.ino

#include "pitches.h"

// notes in the melody:
int melody[] = {
  NOTE_C5, NOTE_D5, NOTE_E5, NOTE_F5, NOTE_G5, NOTE_A5, NOTE_B5, NOTE_C6};
int duration = 500;  // 500 miliseconds

void setup() {

}

void loop() {  
  for (int thisNote = 0; thisNote < 8; thisNote++) {
    // 在 pin 13 上輸出聲音,每個音階響 0.5 秒
    tone(13, melody[thisNote], duration);
    
    // 間隔一段時間後再播放下一個音階
    delay(1000);
  }
  
  // 兩秒後重新播放 
  delay(2000);
}
