15.6. MakeCode Programming#

15.6.1. Step 1#

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


We need to add a package for programming, . Click “Extensions” in the bottom of the drawer and search with “PlanetX” in the dialogue box to download it.


Note: If you met a tip indicating that the codebase will be deleted due to incompatibility, you may continue as the tips say or build a new project in the menu.

15.6.3. Code as below:#


15.6.5. Result#

  • The rotation speed of the fan is adjusted by the potentiometer.

15.7. Python Programming#

15.7.1. Step 1#
