Click “Advanced” in the MakeCode to see more choices.

For programming, we need to add a package: click “Extensions” at the bottom of the MakeCode drawer and search with “iot-environment-kit” in the dialogue box to download it.

Notice: If you met a tip indicating that some codebases would be deleted due to incompatibility, you may continue as the tips say or create a new project in the menu.

5.7. Program

Turn on the lights in accordance with the micro:bit status, if the micro:bit logo faces upwards it means the nest is in a normal status with the green led turnning on; if the yellow led lights on, it means the micro:bit is in a tilted status which means the nest is tilting to the left/right side; or the red means the nest is upside down now and it requires a re-construction.
