Using ESP 32 with a program to run Room and coil sensor

[crimson_star1]

```*Hi so I get this weird error reading when i run the serial monitor. does not show any readings correctly, i have attached a picture with this.

have a read of how-to-get-the-best-out-of-this-forum
in particular you post is very difficult to read - use code tags</>
also avoid using images of screen output - copy the text and upload it

in the Arduino IDE select Fil;e>Preferences and enable "Verbose output during Compiling and upload" then compile your program again
if there are problems upload the error messages as text
run the program and upload any serial monitor output which shows the problem as text (not an image)
