Learnings

Program size limitation

There is a limit to how large a Micro:bit program can be. Once a program exceeds tha limit, the Python editor will fail when trying to download the .hex file. This was for example the case in the maqueen-rc-car project, where I ended up having to remove parts of the maqueen library to reduce the code size.
