22.6. Quick to Start#
22.6.1. Materials Required and Diagram#
Connect the UV sensor to J1 port and the OLED to the IIC port in the Nezha expansion board as the picture shows.
22.7. MakeCode Programming#
22.7.1. 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.
22.7.2. Step 2#
22.7.3. Code as below:#

22.7.5. Result#
The detected value from the UV sensor displays on the OLED screen.
22.8. Python Programming#
22.8.1. Step 1#
Download the package and unzip it: PlanetX_MicroPython
Go to Python editor
We need to add enum.py and uvlevel.py for programming. Click “Load/Save” and then click “Show Files (1)” to see more choices, click “Add file” to add enum.py and uvlevel.py from the unzipped package of PlanetX_MicroPython.
22.8.2. Step 2#
22.8.3. Reference#
from microbit import *
from enum import *
from uvlevel import *
uvlevel = UVLEVEL(J1)
while True:
display.scroll(int(uvlevel.get_uvlevel()))
22.8.4. Result#
The detected value from the UV sensor displays on the micro:bit.
