- | ## 用蜂鸣器播放音乐 | + | ### 可以在线制作Buzz音乐的工具 |
- | ### 1. 编程蜂鸣器 | + | 源自:[[https://onlinesequencer.net|onlinesequencer]] |
- | + | ||
- | 1.首先从machine库导入Pin和PWM,从utime库导入sleep. | + | |
- | + | ||
- | <code python> | + | |
- | from machine import Pin, PWM | + | |
- | from utime import sleep | + | |
- | </code> | + | |
- | + | ||
- | 2.初始化PWM(也就是脉宽调制)到管脚PIO(22),并分配它为变量buzzer。 | + | |
- | + | ||
- | <code python> | + | |
- | buzzer = PWM(Pin(22)) | + | |
- | </code> | + | |
- | + | ||
- | 3.给变量buzzer分配一个频率属性,选择10到12,000之间的数值,数值越大音调越高,我们可以设定为500. | + | |
- | + | ||
- | <code python> | + | |
- | buzzer.freq(500) | + | |
- | </code> | + | |
- | + | ||
- | 4.将蜂鸣器对象的duty_u16属性设置为1000,这就能让蜂鸣器尽可能地响。更低的值更安静,0根本没有声音。 | + | |
- | + | ||
- | <code python> | + | |
- | buzzer.duty_u16(1000) | + | |
- | </code> | + | |
- | + | ||
- | 5.设置1秒的延迟,然后将duty设置为0,这样声音就会停止。如果不这样做,即使程序执行完毕,嗡嗡声也会继续。 | + | |
- | + | ||
- | <code python> | + | |
- | sleep(1) | + | |
- | buzzer.duty_u16(0) | + | |
- | </code> | + | |
- | + | ||
- | 最终的代码: | + | |
- | + | ||
- | <code python> | + | |
- | from machine import Pin, PWM | + | |
- | from utime import sleep | + | |
- | + | ||
- | buzzer = PWM(Pin(22)) | + | |
- | buzzer.freq(500) | + | |
- | buzzer.duty_u16(1000) | + | |
- | sleep(1) | + | |
- | buzzer.duty_u16(0) | + | |
- | </code> | + | |
- | + | ||
- | ### 2. 播放音乐 | + | |
- | 因为你可以使用不同的频率,你可以创造一个完整的音符阵列。网上有一些音符频率的列表,其中许多可以追溯到[[https://github.com/bhagman/Tone|Brett Hagman在Github上的Arduino音调库]]。我们将使用这些值创建一个列表,以便在代码早期播放任何歌曲。 | + | |
- | + | ||
- | 1.在管脚PIO(22)上导入必要的库并初始化PWM。 | + | |
- | + | ||
- | <code python> | + | |
- | from machine import Pin, PWM | + | |
- | from utime import sleep | + | |
- | + | ||
- | buzzer = PWM(Pin(22)) | + | |
- | </code> | + | |
- | + | ||
- | 2.使用下列值创建一个名为tones的字典。 | + | |
- | + | ||
- | <code python> | + | |
- | tones = { | + | |
- | "B0": 31, | + | |

- | 3.为你的歌曲创建一个音符列表(又名数组)。用字母P表示音乐中的停顿。每个音符都应该用引号括起来。 | + | |
- | + | ||
- | <code python> | + | |
- | song = ["E5","G5","A5","P","E5","G5","B5","A5","P","E5","G5","A5","P","G5","E5"] | + | |
- | </code> | + | |
- | + | ||
- | 向在这个帖子上分享这段著名riff音符的人们致敬。 | + | |
- | + | ||
- | 4.创建一个名为playtone的函数,可以使用任意频率并以最大音量播放。 | + | |
- | + | ||
- | <code python> | + | |
- | def playtone(frequency): | + | |
- | buzzer.duty_u16(1000) | + | |
- | buzzer.freq(frequency) | + | |
- | </code> | + | |
- | + | ||
- | 5.创建一个名为bequiet的函数,通过将duty_u16更改为0来使蜂鸣器静音。 | + | |
- | + | ||
- | <code python> | + | |
- | def bequiet(): | + | |
- | buzzer.duty_u16(0) | + | |
- | </code> | + | |
- | + | ||
- | 6.创建一个名为playsong的函数,您将使用它来遍历音符数组并播放每一个音符,或者在看到P时暂停。 | + | |
- | + | ||
- | <code python> | + | |
- | def playsong(mysong): | + | |
- | for i in range(len(mysong)): | + | |
- | if (mysong[i] == "P"): | + | |
- | bequiet() | + | |
- | else: | + | |
- | playtone(tones[mysong[i]]) | + | |
- | sleep(0.3) | + | |
- | bequiet() | + | |
- | </code> | + | |
- | + | ||
- | 是这样的。首先,我们创建一个for循环来遍历myssong数组中的所有值。如果值等于P,则触发be quiet;如果值不等于P,则触发playtone。注意,playtone需要一个数字频率值,因此我们必须从音调列表中获取每个音符的数字。如果我们只是播放tone(myssong [i]),它将失败,因为它将尝试播放字符串“E5”,而不是频率659,这是它需要的整数。 | + | |
- | + | ||
- | 对于每个音调或暂停,系统维持0.3秒的睡眠状态。如果你想要更快的节奏,你可以降低时间。如果你想要慢节奏,那就加快节奏。 | + | |
- | + | ||
- | 7.使用song参数触发playsong函数。 | + | |
- | + | ||
- | <code python> | + | |
- | playsong(song) | + | |
- | </code> | + | |
- | + | ||
- | 运行此代码时,您将听到蜂鸣器播放熟悉的旋律。完整的代码应该是这样的: | + | |
- | + | ||
- | <code python> | + | |
- | from machine import Pin, PWM | + | |
- | from utime import sleep | + | |
- | buzzer = PWM(Pin(15)) | + | |
