Error Codes

Your micro:bit may encounter a situation that prevents it from running your code. When this happens, a frowny face will appear on your micro:bit screen followed by an error number.

Wanneer dit gebeurt, dan zou je het volgende moeten doen:

• Press the reset button on the back of the device to restart your program.
• Flash the script to your micro:bit again.

If the problem persists please report the issue to us.
