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

../_images/05001_072.png

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())
    display.scroll(str(light_value))
    sleep(2000)

2.8.4. Result#

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