8.5. Outlook#


8.6. Quick to Start#

8.6.1. Materials Required and Diagram#

Connect the Sonar:bit to J1 port and the OLED module to the IIC port in the Nezha expansion board as the picture shows.


8.7. MakeCode Programming#

8.7.1. Step 1#

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


We need to add a package for programming, . Click “Extensions” in the bottom of the drawer and search with “PlanetX” in the dialogue box to download it.


Note: If you met a tip indicating that the codebase will be deleted due to incompatibility, you may continue as the tips say or build a new project in the menu.

8.7.2. Step 2#

8.7.3. Code as below:#


8.7.5. Result#

The distance value displays on the OLED module.

8.8. Python Programming#

8.8.1. Step 1#

Download the package and unzip it: PlanetX_MicroPython

Go to Python editor


We need to add enum.py and distance.py for programming. Click “Load/Save” and then click “Show Files (1)” to see more choices, click “Add file” to add enum.py and distance.py from the unzipped package of PlanetX_MicroPython.
