Primeiro passo: o projeto
O que é?
Shake your micro:bit and be given a random direction to walk. You will learn about variables, and using random numbers, selection and comparison logic blocks.
Estes dois vídeos mostram o que você fará e como desenvolver o código:
Introdução
Código
Como funciona:
- The program uses a variable called “direction” to store a random number.
- Variables store numbers or values that can change in a computer program.
- Shake the micro:bit to set “direction” to a random number between one and three.
- The program then uses selection and comparison logic blocks to test the value of the variable.
- If “direction” is equal to 1, then an arrow pointing north shows on the micro:bit’s LED display. If “direction” is equal to 2, then the arrow points east. Otherwise, the arrow points west.
- To make the battery last longer, the program pauses for half a second after the arrow appears then clears the screen.
Itens necessários:
- Um micro:bit (ou simulador MakeCode);
- Editor MakeCode;
- battery pack (optional but recommended)
- our set-up guide may be useful
Segundo passo: é hora de programar
Terceiro passo: vamos deixar o código ainda melhor
- Add more directions.
- Use buttons to show icons for skipping, running, and jumping.
- Combine with the touch stopwatch program to make a motivational tool to use in sports lessons.
Thanks to David Hay, an educator in Alberta, Canada for sharing this brilliant project idea with us.
