# Arduino与蜂鸣器奏响欢乐斗地主
## tone()函数
Arduino 的 `tone()`函数可以在一个引脚上产生一个特定频率的方波,占空比 50%，持续时间可以设定。而 `noTone()`函数则关闭该引脚上的脉冲信号输出。在这个引脚上连接一个蜂鸣器，就能发出 Tone()函数指定频率的声音。如果这个引脚已经在播放音乐， 改变 tone()的频率值，蜂鸣器就会改变发声音调。
## 简谱知识
### 音的高低
基本音符：1，2，3，4，5，6，7
此外，还有倍高音与倍低音
倍高音是在数字上加2个点，倍低音是在数字下方加2个点
### 音的长短
在简谱中，把 `1 2 3 4 5 6 7` 称为4分音符
- 在数字下方加1条横线，则变为8分音符（音长减小一半），加2条横线变为16分音符（音长再减小一半）
- 在数字右边加1条横线，变为2分音符（音长增加一倍）
- 在数字右边加1个点，音长在原来基础上增加1/2
### arduino中音的高低表示方法
在arduino中，有一个 `pitches.h`文件，其定义了“1 2 3 4 5 6 7”这几个音符的频率以及它们相应高低音的频率，内容如下：

其中，用 `C D E F G H A B` （注意顺序）来分别代表 `1 2 3 4 5 6 7`
- 用 `C4`代表代表 1，`C3`代表 1的低音，`C2`代表超低音，以此类推
- 用 `C5`代表 1的高音，`C6`代表超高音，以此类推
