Hello guys.
I am working on an Arduino Nano 328 project with a 20x4 I2C display.
In the project I only have the component included but when compiling I get a bug that I don't know how to correct.

I attach the program and catch the compilation failures, I think it is a component failure but I'm not sure.

Thank you
