Micro: bit Fundamental Course--Button&Display

In our last blog micro bit course Start Your Micro:bit Programming Trip we have talked about the basic operation method of Microsoft Makecode. In the following micro bit tutorial, we will teach you some fundamental functions of blocks one by one .

Our purpose:

To know basic usage of Makecode through studying buttons and blocks.

On Micro:bit, there are 5*5 LED metric dot display and 2 buttons. And today we are going to learn how to use button and LED display together.

Our requirement:

Press down a button to display its relative direction. Press 2 buttons together for clearing the display.

Procedure:

Micro bit curriculum step 1: Drag out block "on button pressed" from Input column and set the button to be "A".

Under block "on button A pressed", we insert block "show arrow", which can make micro:bit to display directions with arrow. And here we set direction to be "west".
