Корак 1: Уради

Шта је ово?

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.

Ова два видео-записа показују шта треба да направите и како то да програмирате:


Водич за програмирање

Како то ради

  • 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.

Шта вам је потребно

  • micro:bit (или симулатор у MakeCode)
  • MakeCode едитор
  • battery pack (optional but recommended)
  • our set-up guide may be useful

Корак 2: Програмирај

Корак 3: Унапреди

  • 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.
