7.7.5. Result¶
The color of the detected object displays on the OLED module.
7.8. Python Programming¶
7.8.1. Step 1¶
Download the package and unzip it: PlanetX_MicroPython
Go to Python editor
We need to add color.py for programming. Click “Load/Save” and then click “Show Files (1)” to see more choices, click “Add file” to add color.py from the unzipped package of PlanetX_MicroPython.

from microbit import *
from color import *
color = COLOR()
while True:
display.scroll(color.get_hue())
7.8.4. Result¶
The HUE value displays on the micro:bit.
