This error usually means that you have not installed the library that provides the file of that name. Most often, you can search for the library in the Arduino Library Manager (accessible via Sketch > Include Library > Manage Libraries... in the Arduino IDE menus), then install it there. The one thing you should be aware of is that the header file names don't necessarily always match the library name, so you might have to be a bit creative in your search keywords, and maybe try your luck on Google if you don't find the library in Library Manager.
But I'm wondering about this specific file "Audrino.h". Perhaps it's a play on the name "Arduino", or maybe you just spelled the file name wrong and you actually meant to write "Arduino.h"? If the latter, then there is no need to install the library because it is part of each Arduino boards platform, which you will have already installed on your computer.
