MicroPython示例

• 以下是microbit内置的音乐旋律,import music,后可使用music.play播放

music.DADADADUM music.ENTERTAINER music.PRELUDE music.ODE music.NYAN music.RINGTONE music.FUNK music.BLUES music.BIRTHDAY music.WEDDING music.FUNERAL music.PUNCHLINE music.PYTHON music.BADDY music.CHASE music.BA_DING music.WAWAWAWAA music.JUMP_UP music.JUMP_DOWN music.POWER_UP music.POWER_DOWN

from microbit import *
import music

i = None


while True:
  if button_a.is_pressed():
    music.play(music.NYAN, pin0, wait=True, loop=False)
  if button_b.is_pressed():
    music.stop(pin0)
