Materials Required and Diagram​

Connect the Soil moisture sensor to J1 port and the OLED module to IIC port in the Nezha expansion board as the picture shows.

MakeCode Programming​

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.

Step 2​

Code as below:​

Result​

The value of the current soil moisture display on the OLED module.

Python Programming​

Step 1​

Download the package and unzip it: PlanetX_MicroPython

Go to Python editor

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

Step 2​

Reference​


from microbit import *
from enum import *
from soilhumidity import *

while True:
    soilhumidity = SOILHUMIDITY(J1)
    soilhumidity_value = int(soilhumidity.get_soilhumidity())
    display.scroll(str(soilhumidity_value))

Result​

The value of the current soil moisture display on the micro:bit.
