2.5. Outlook#


2.6. Quick to Start#

2.6.1. Materials Required and Diagram#

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


2.7. MakeCode Programming#

2.7.1. 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.

2.7.2. Step 2#

2.7.3. Code as below:#


2.7.5. Result#

The light intensity’s value displays on the OLED module.

2.8. Python Programming#

2.8.1. Step 1#

Download the package and unzip it: PlanetX_MicroPython

Go to Python editor


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

2.8.2. Step 2#

2.8.3. Reference#

from microbit import *
from enum import *
from light import *

while True:
    light = LIGHT(J1)
    light_value = int(light.get_lightlevel())

2.8.4. Result#

The light intensity’s value displays on the micro:bit.
