In our last blog  Start Your Micro:bit Programming Trip we have talked about the basic operation method of Microsoft Makecode. In the following articles, 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.

Procedure:

Step 1: Drag out block "on button pressed" from Input column and set the button to be "A".
