46.3. MakeCode Programming#

Step 1#

Click “Advanced” in the MakeCode drawer to see more choices.

../../_images/neza-inventor-s-kit-case-37-04.png

For programming Nezha Breakout Board, we need to add a package. Search with “Nezha” in the dialogue box and click to download it.

Notice: If you met a tip indicating that some codebases would be deleted due to incompatibility, you may continue as the tips say or create a new project in the menu.

Step 2#

Code as the picture suggests#

Result#

First manually adjust the opening angle of the mechanical claw, then turn on the power, press the button A, the car will travel forward for a certain distance and grab the object.

Thinking#

Is it possible to make a car that can turn directions and grab objects with this kit?
