14.8. Python Programming#
14.8.1. Step 1#
Download the package and unzip it: PlanetX_MicroPython
Go to Python editor
We need to add enum.py and laser.py for programming. Click “Load/Save” and then click “Show Files (1)” to see more choices, click “Add file” to add enum.py and laser.py from the unzipped package of PlanetX_MicroPython.
14.8.2. Step 2#
14.8.3. Reference#
from microbit import *
from enum import *
from laser import *
laser = LASER(J1)
while True:
laser.set_laser(1)
sleep(500)
laser.set_laser(0)
sleep(500)
14.8.4. Result#
The Laser module lights on for 500ms and then lights off for 500ms after powering on.
