Sample Code
Makecode programs: light and temperature monitor
Result
Press down button A, send the current temperature value to the workshop; the first line of the OLED screen displays the temperature value. Press down button B, send the current light value to the workshop; the second line of OLED screen displays the light value.
T for temperature; L for Light
