[讨论] Arduino控制蜂鸣器播放音乐

[复制链接]

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[thisNote];
//主节拍  这里的8是指Arduino 8号引脚
    tone(8, melody[thisNote], 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
}

pitches.h内容是把音符做定义

大谱表与钢琴键盘对照表

20201213012414771.jpg

">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
20201213015344936-1.gif
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[thisNote];
    tone(8, melody[thisNote], noteDuration);
    int pauseBetweenNotes = noteDuration * 1.30;
    delay(pauseBetweenNotes);
    noTone(8);
  }
}
