Hardware connection

Here we take the wukong expansion board as an example.

Connect the motor to the M1 interface of the expansion board.

Add a dedicated extension library

Click "Advanced" in the code drawer of MakeCode to view more code options.

In order to program the Nezha expansion board, we need to add an extension library. Find "Extension" at the bottom of the code drawer and click it. A dialog box will pop up, search for "Nezha", and then click to download this code library.

Note: If you get a prompt saying that some code libraries will be deleted due to incompatibility, you can continue according to the prompt, or create a new project in the project menu bar.

Write the program as shown

Reference Program

Please refer to the program link: https://makecode.microbit.org/_U3p38hgW2d33

You can also download the program directly from the following website, and start running the program after downloading.

### Result

When button A is pressed, the motor rotates, and when button B is pressed, the motor stops rotating.

Notes

Note: When using the motor, you should pay attention to whether the motor is stuck. If the motor is stuck, there may be a risk of burning.
