步驟1:製作

這是什麼?

Play different tunes by using the micro:bit’s touch sensor.

這兩個影片向您展示了製作內容和編碼方式:

編程指引

運作方式

  • This project is the same as the Jukebox project but instead of using the micro:bit’s buttons, you’ll make your own input device using cardboard covered in strips of tin foil connected by crocodile clip leads to the micro:bit's pins.
  • Flash the program onto your micro:bit.
  • Attach one end of three crocodile clip leads to pins 1, 2 and GND (ground or Earth pin). Attach the other ends to a cardboard guitar or keyboard.
  • With one finger touch the foil connected to GND, and with another finger touch the foil connected to pin 1 and then pin 2. It should play a different tune depending on which strip of foil you touch.
  • The micro:bit is using pins 1 and 2 as touch inputs. When you touch either of these pins and the GND pin, you’re completing an electrical circuit. A small amount of electricity flows through you, the micro:bit can detect it and the program triggers the playing of a tune.
  • If you do not have a V2 micro:bit, which plays sound, attach headphones to pins 0 and GND.

你需要的東西

  • micro:bit和選配電池组
  • MakeCode 或, Python 編輯器
  • three crocodile clip leads
  • cardboard, tin foil, glue stick and scissors to make a guitar or keyboard
  • optional headphones, buzzer, or speaker with additional two crocodile clip leads for V1 users

步驟2:編碼

6        music.play(music.ODE)
7    if pin2.is_touched():

步驟3:進階

  • Change the tunes that are played when you touch the tin foil.
  • 編寫自己的音樂。
  • Show different pictures, letters, numbers, or words depending on which tune you picked.
