Arduino蜂鸣器欢乐颂程序是一种使用Arduino控制蜂鸣器播放《欢乐颂》音乐的程序。下面是一个简单的示例代码:
```cpp
// 定义蜂鸣器引脚
int buzzerPin = 8;
// 定义音符频率数组
int melody[] = {
659, 659, 0, , 0, 523, 659,0, 784, 0, 0, 0, 392, 0, , 0,
659, 659 0, 659, 0, 523, 659, 0, 784, 0, 0, 0, 392 0, 0, 0,
659, 659, 0, 659, 0, 523, 659, 0, 784, 0, 0, 0, 784, 0, 0, 0,
880, 0, 0, 698, 0, 0, 659, 0, 587, 0, 0, 0, 587, 0, 0, 523,
};
// 定义音符时长数组
int noteDurations[] = {
8, 8, 16, 8, 16, 8, 8, 16, 8, 16, 16, 16, 8, 16, 16, 16,
8, 8, 16, 8, 16, 8, 8, 16, 8, 16, 16, 16, 8, 16, 16, 16,
8, 8, 16, 8, 16, 8, 8, 16, 8, 16, 16, 16, 8, 16, 16, 16,
8, 16, 16, 8, 16, 16, 8, 16, 16, 16, 8, 16, 16, 8, 8, 4,
};
void setup() {
// 设置蜂鸣器引脚为输出模式
pinMode(buzzerPin, OUTPUT);
}
void loop() {
// 播放音乐
for (int i = 0; i < sizeof(melody) / sizeof(int); i++) {
int noteDuration = 1000 / noteDurations[i];
tone(buzzerPin, melody[i], noteDuration);
int pauseBetweenNotes = noteDuration * 1.30;
delay(pauseBetweenNotes);
noTone(buzzerPin);
}
}
```
这段代码使用了Arduino的`tone()`函数来控制蜂鸣器发声,通过定义音符频率数组和音符时长数组来播放《欢乐颂》的音乐。在`setup()`函数中,将蜂鸣器引脚设置为输出模式;在`loop()`函数中,使用循环来播放音乐。
