1. Learning objectives
In this course, we mainly learn how to display temperature and humidity through MakeCode graphical programming.
2. Sensor wiring
The temperature and humidity sensor is connected to the P1P2 interface.

3. Programming
Method 1 Online programming:
First, connect micro:bit to the computer via a USB cable, a USB flash drive will pop up on the computer, click the URL in the USB flash drive:https://makecode.microbit.org/ to enter the programming interface.Then, add the Yahboom software package https://github.com/YahboomTechnology/SuperBitLibV2 to start programming.
Method 2 Offline programming:
Open the offline programming software MakeCode and enter the programming interface. Click [New] and add the Yahboom software package https://github.com/YahboomTechnology/SuperBitLibV2 to start programming.
3.1 Adding extension packages


3.2 Building blocks used
The locations of the building blocks required for this programming are shown in the figure below.


3.3 Combining blocks
The summary procedure is shown in the figure below.
You can also directly open the Read-temperature-humidity.hex file provided in this experiment and drag it into the browser that opens the URL, and the program diagram of this project source code will be automatically opened.
4. Experimental Phenomenon
After the program runs successfully, the dot matrix displays a heart, then the current temperature, then a chessboard, and then the humidity.
