Micro:bit自带一个有趣的功能就是可以生成音乐播放，今天做一个简单实用的案例，用Micro:bit播放生日快乐歌。
算法：
按下按键A，显示生日快乐
播放D
播放D
播放E
播放D
播放G
播放F
休息
为了播放音乐，需要将一个可以3V工作的蜂鸣器或者耳机，播放器连到Micro:bit的GND和Pine0脚之间，如下图
Blocky程序如下
MicroPython程序脚本如下：
from microbit import *
import music
tune = ["E4:4", "E4:4","E4:8", "E4:4", "E4:4", "E4:8","E4:4", "G4:4", "C4:4", "D4:4","E4:8", "F4:4", "F4:4", "F4:4","F4:4", "F4:4",
"E4:4", "E4:4", "E4:2","E4:2", "E4:4", "D4:4", "D4:4","E4:4", "D4:8", "G4:8", "E4:4","E4:4", "E4:8", "E4:4", "E4:4","E4:8",
"E4:4", "G4:4", "C4:4","D4:4", "E4:8", "F4:4", "F4:4","F4:4", "F4:4", "F4:4", "E4:4","E4:4", "E4:2", "E4:2", "G4:4","G4:4",
"F4:4", "D4:4", "C4:8"]
while True:
if button_a.is_pressed():
music.play(tune)
下载就可以播放啦。
