  • The color of the detected object displays on the OLED module.

7.7. Python Programming


Step 1

Download the package and unzip it: PlanetX_MicroPython

Go to Python editor

Step 2

Reference

from microbit import *
from color import *
color = COLOR()
while True:
    display.scroll(color.get_hue())

Result

  • The HUE value displays on the micro:bit.
