Below you will find three links. We have produced the code for each of the experiments, for each of the additional challenges, and also Python versions of each of the experiments. Each of the downloads are zip files, which will need to be unzipped to access the code examples. We have included two versions for each python experiment, a HEX file and a PY file.
Connect the micro:bit to a spare USB port on your computer. The micro:bit will show up as a removable disk drive in File Explorer (Windows). Once unzipped, the individual MakeCode files can be dragged and dropped onto the micro:bit in File Explorer (Windows). An orange light will begin to flash on the rear side of the micro:bit, once the flashing stops the transfer is complete and the program can be run. Alternatively, the files can be dragged and dropped directly into the MakeCode editor.
Connect the micro:bit to your computer in the same way as outlined above. The HEX versions can be dragged and dropped onto the micro:bit in the same was a MakeCode HEX files. Alternatively, the files can be dragged and dropped directly into the Python editor or a Python ready editor of your choice.
