What do you see printed in the Arduino IDE Serial Monitor? Does the board automatically reboot?

When running “Read the RFID Card UID” it runs automatically 3 or 4 times and blocks! Any ideas, please?

Hi.
At the moment, we don’t have for micropython.
But, I’ll add that to my list.
Thanks for the suggestion.

They have inspired me to delve into this. Is there a chance you are working on a version for Micropython? Thanks again!
