With IoT, you can measure various things. This time I would like to use Arduino to measure whether the light is shining and the temperature.

I attached an optical sensor and a temperature sensor to the Arduino and tried two things: “When it gets dark, the LED lights up” and “Display the current temperature on the display”.
(1) The LED lights up when it gets dark
