### 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](https://github.com/lionyhw/PlanetX_MicroPython/archive/master.zip)

Go to   [Python editor](https://python.microbit.org/v/2.0)

### 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.
