2.3. 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 the Ultrasonic Sensor, we need to add a package. Search with “PlanetX” in the dialogue box and click to download it.

../../_images/neza-inventor-s-kit-case-37-05.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#

After powering on, the mechanical shrimp moves forward and waves the princers, it will turn the directions if there is obstacles being detected. ../../_images/case_0101.gif
