Failed to connect to ESP32 for home automation project.

Question

Hi everyone, I am trying to create a home automation project. I would use three sensors in the start to check the project's working, but I am unable to program my ESP32. It was working fine yesterday, but now it says, "Failed to connect to ESP32, no serial data received."

Be sure your USB cable has data wires in it. 
 Check that the correct com port is selected - it sometimes changes 
 Try the reset button on the ESP32 while the connecting dots are coming. 
 Ensure you have Silicon Labs CP2102 drivers installed. 
 Somebody made a video about how to press the buttons and other methods...
