Arduino控制蜂鸣器播放音乐
### 框架结构
```
//引用pitches.h库文件
#include "pitches.h"
int melody[] = {
//以下都是音符（do,re,mi,fa,so,la,xi）
NOTE_C4, NOTE_G3, NOTE_G3, NOTE_A3, NOTE_G3, 0, NOTE_B3, NOTE_C4
};
int noteDurations[] = {
//以下是写每一个音符的长短（1/8音符=8，1/4音符=4，1/2音符=2）
4, 8, 8, 4, 4, 4, 4, 4
};
void setup() {
//需要播放的音符的数量=8
for (int thisNote = 0; thisNote < 8; thisNote++) {
int noteDuration = 1000 / noteDurations;
//主节拍这里的8是指arduino 8号引脚
tone(8, melody, noteDuration);
int pauseBetweenNotes = noteDuration * 1.30;
delay(pauseBetweenNotes);
//停止播放
noTone(8);
}
}
void loop() {
// for循环写在这里表示循环播放
}
```

### 大谱表与钢琴键盘对照表
### 简谱对照表
然后我们就可以对照着简谱表，把内容写入进去了
以下是欢乐颂简谱
音符的长短，只有数字的就写4，有下划线的就写8（两个下划线连在一起的就写8, 8, ），上面有括号的就写2（两个上括号连一起的就写2, 2, ），中横线就写0
以下就是欢乐颂简谱转换成的代码，上传到Arduino就可以听到蜂鸣器演奏啦
```
#include "pitches.h"
int melody[] = {
NOTE_E4, NOTE_E4, NOTE_F4, NOTE_G4,
NOTE_G4, NOTE_F4, NOTE_E4, NOTE_D4,
NOTE_C4, NOTE_C4, NOTE_D4, NOTE_E4,
NOTE_E5, NOTE_D4, NOTE_D4, 0,
NOTE_E4, NOTE_E4, NOTE_F4, NOTE_G4,
NOTE_G4, NOTE_F4, NOTE_E4, NOTE_D4,
NOTE_C4, NOTE_C4, NOTE_D4, NOTE_E4,
NOTE_D5, NOTE_C4, NOTE_C4, 0,
NOTE_D4, NOTE_D4, NOTE_E4, NOTE_C4,
NOTE_D4, NOTE_E4, NOTE_F4, NOTE_E4, NOTE_C4,
NOTE_D4, NOTE_E4, NOTE_F4, NOTE_E4, NOTE_D4,
NOTE_C4, NOTE_D4, NOTE_G5, NOTE_E4,
NOTE_E4, NOTE_E4, NOTE_F4, NOTE_G4,
NOTE_G4, NOTE_F4, NOTE_E4, NOTE_D4,
NOTE_C4, NOTE_C4, NOTE_D4, NOTE_E4,
NOTE_D5, NOTE_C4, NOTE_C4, 0
};
int noteDurations[] = {
4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 8, 4, 4,
4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 8, 4, 4,
4, 4, 4, 4, 4, 8, 8, 4, 4, 4, 8, 8, 4, 4, 4, 4, 4, 2,
2, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 8, 4, 4
};
void setup() {
}
void loop() {
for (int thisNote = 0; thisNote < 66; thisNote++) {
int noteDuration = 1000 / noteDurations;
tone(8, melody, noteDuration);
int pauseBetweenNotes = noteDuration * 1.30;
delay(pauseBetweenNotes);
noTone(8);
}
}
```
