Primeiro passo: o projeto
O que é?
Play different tunes by using the micro:bit’s touch sensor.
Estes dois vídeos mostram o que você fará e como desenvolver o código:
- 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.
- Um micro:bit e um conjunto de baterias (opcional);
- Editor MakeCode ou Python;
- 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
Segundo passo: é hora de programar
Terceiro passo: vamos deixar o código ainda melhor
- Change the tunes that are played when you touch the tin foil.
- Programe suas próprias melodias.
- Show different pictures, letters, numbers, or words depending on which tune you picked.
