Modules Connection Diagram¶
Click “Advanced” in the drawer of the MakeCode 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.
Connect to Kids’IoT platform, User Token is the only indentification code for the account which can not be revised.
Topic is the only indentification code and you have to appoint the updload device when connecting. The device number(Topic) will be in sequential order.
Upload an integer to KidsIoT and it shows here.
Judge if the conection status is successful, “Ture” for success, “False” for failure. You can edit the reconnection system to ensure the stable connection.
When getting connected well, you can click this switch to operate these two bricks.
