ステップ1: 作る

説明

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.

この2つのビデオで、何を作り、どのようにコーディングするかご案内します。

はじめに

プログラミングガイド

動作の仕組み

  • 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.

必要なもの

  • micro:bit(またはMakeCodeシミュレーター)
  • MakeCodeエディター
  • battery pack (optional but recommended)

ステップ2: プログラムする

ステップ3: 改善する

  • 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.
