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.

Step 2

Code as below:

Result

  • The rotation speed of the fan is adjusted by the potentiometer.

15.7. Python Programming


Step 1

Download the package and unzip it: PlanetX_MicroPython

Go to Python editor

Step 2

Reference

from microbit import *
from enum import *
from fans import *
fans = FANS(J1)
while True:
    fans.set_fans(1,100)
    sleep(3000)
    fans.set_fans(1,50)
    sleep(3000)
    fans.set_fans(0)
    sleep(3000)

Result

  • After powering on, the Motor fan module rotates for 3 seconds at the speed of 100% first and then at the speed of 50% for another 3 seconds, and finally stops for 3 seconds.
