Paso 1: Hazlo

¿Qué es?

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

Estos dos vídeos te enseñarán qué vas a hacer y cómo programarlo:


Guía de programación

Cómo funciona

  • 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.

  • Editor de MakeCode o de Python
  • three crocodile clip leads
  • cardboard, tin foil, glue stick and scissors to make a guitar or keyboard
