Save & Edit Scripts

It’s always a good idea to save your scripts so that you can open and improve them later.  This activity’s step-by-step video and matching checklist instructions show how to save and reopen a script.

Make sure to follow along with your own computer and micro:bit module.

• Enter the script below into the micro:bit Python Editor.  (It’s just the default script with HEART changed to HAPPY and ‘Hello’ changed to ‘Hi!’.)

# Imports go at the top
from microbit import *

# Code in a 'while True:' loop repeats forever
while True:
    display.show(Image.HAPPY)
    sleep(1000)
    display.scroll('Hi!')

• Click the Edit project name icon, to the left of the ‘Untitled project’ name.
• Change the name to happy-image-hi-text, and click Confirm.
• Click the Save button.

• Close the Project saved popup.
• Verify that the name changed from ‘Untitled project’ to ‘happy-image-hi-text’.

• Open a file browser (Windows Files Explorer, Mac Finder, or Chromebook Files).  
• Check your Downloads folder and make sure you can find happy-image-hi-text.hex.

• Change to the existing script so that you can verify the change reverts when you open the script you just saved.  

• Click the micro:bit Python Editor’s Open button
• Select happy-image-hi-text in the Open dialog
• Then click the Open button.  
• Lastly, click Replace in the ‘Confirm replace project’ popup.
• Verify that the script changes back to the version you saved.
