You have three switches in one room and a single light bulb in another room. You are allowed to visit the room with the light bulb only once. How do you figure out which switch controls the bulb? Write your answer in the comments before looking at other answers.

Remove the switches put a microcontroller like esp32, connected via wifi to an app on your phone. Go to the other room and see which switch switches on the bulb.

If there is no wifi, why the hell do you want a programmer. I can't work without internet.

ESP32 proceeds to explode with 230VAC

Don't worry I power it with a Chinese adapter nothing of blowing up happens here. Also I have an app for it.
