Arduino 蜂嗚器程式控制

蜂鳴器分為電磁式及壓電式兩種， 電磁式：由電流驅動，聲音較大但較為耗電。 壓電式：半導體電壓轉換陶磁片振動，由電壓驅動(陶磁片)，較省電但聲音較小。  無論電磁式或壓電式依其驅動方式又分為兩種，自激式與他激式。 自激式：內藏驅動電路，只需直流電即可動作。 他激式：內無驅動電路，需加入交流電源及動作訊號才可動作。

基本發聲控制

const int buzzer = 4; // 蜂鳴器位於 pin 4

// 開發板啟動時，此區塊的程式碼運行1次
void setup(){
 
  pinMode(buzzer, OUTPUT); // 設定蜂鳴器為OUTPU為輸出模式
  
}

// 開發板啟動後，重複執行此區塊程式碼
void loop(){
 
  tone(buzzer, 1000); // 1000Hz 音頻
  delay(1000);        // 間隔1秒
  noTone(buzzer);     // 停止
  delay(1000);        // 間隔1秒
  
}

變換歌的曲調只要將音符頻率更換就可以了

#define NT0 -1
#define NT1 294
#define NT2 330
#define NT3 350
#define NT4 393
#define NT5 441
#define NT6 495
#define NT7 556

#define NTL1 147
#define NTL2 165
#define NTL3 175
#define NTL4 196
#define NTL5 221
#define NTL6 248
#define NTL7 278

#define NTH1 589
#define NTH2 661
#define NTH3 700
#define NTH4 786
#define NTH5 882
#define NTH6 990
#define NTH7 112

如果是換歌，就要更換節拍跟音符
