Primeiro passo: o projeto
O que é?
Turn your BBC micro:bit into a water bottle alert, so you can tell if someone else has drunk from it. You will learn how to use the micro:bit's LED display and accelerometer.
Estes dois vídeos mostram o que você fará e como desenvolver o código:
Como funciona:
- The micro:bit shows a heart on its LED display when your water bottle is upright.
- The LED display shows a warning cross when a tilt is detected by the micro:bit’s accelerometer. The cross stays there until you reset the program by pressing the reset button on the back of the micro:bit or by disconnecting and reconnecting the battery.
- An accelerometer measures forces in three dimensions, including gravity, so your projects can tell which way up your micro:bit is.
Itens necessários:
- Um micro:bit (ou simulador MakeCode);
- Editor MakeCode;
- Conjunto de baterias;
- our set-up guide may be useful
Segundo passo: é hora de programar
Terceiro passo: vamos deixar o código ainda melhor
- Find a way to reset the program without using the micro:bit’s reset button, for example by pressing button A or B to show a heart icon.
- Add an audible alarm using blocks from the music section of the MakeCode editor.
