The detected value displays on the OLED screen.
Python Programming
Step 1
Download the package and unzip it: PlanetX_MicroPython
Go to Python editor
We need to add enum.py and trimpot.py for programming. Click "Load/Save" and then click "Show Files (1)" to see more choices, click "Add file" to add enum.py and trimpot.py from the unzipped package of PlanetX_MicroPython.
Step 2
Reference
from microbit import *
from enum import *
from trimpot import *
trimpot = TRIMPOT(J1)
while True:
display.scroll(trimpot.get_analog())
Result
The detected value of the Analog Rotation Potentiometer displays on the micro:bit.
