Click “Advanced” in the MakeCode drawer to see more choices.
We need to add a package for programming, . Click “Extensions” in the bottom of the drawer and search with “PlanetX” in the dialogue box to download it.
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.
9.7.2. Step 2#
9.7.3. Code as below:#
The LED lights on if the crash switch was pressed or it lights off.
9.8. Python Programming#
9.8.1. Step 1#
Download the package and unzip it: PlanetX_MicroPython
Go to Python editor
We need to add enum.py and crash.py for programming. Click “Load/Save” and then click “Show Files (1)” to see more choices, click “Add file” to add enum.py and crash.py from the unzipped package of PlanetX_MicroPython.
9.8.2. Step 2#
from microbit import * from enum import * from crash import * crash = CRASH(J1) while True: button = crash.crash_is_pressed() if(button == True): display.show(Image.HAPPY) else: display.show(Image.SAD)
A smile face displays on the micro:bit while the crash switch being pressed or the micro:bit displays a sad face.
