why i cant connect to arduino with simulink ?

### Starting build procedure for model: untitled Code Generation 2 1 Elapsed: 11 sec ### Generating code into build folder: C:\Users\Pirouz\Desktop\New folder (2)\untitled_ert_rtw The file containing block diagram 'untitled' is shadowed by a file of the same name higher on the MATLAB path. This can cause unexpected behavior. For more information see "Avoiding Problems with Shadowed Files" in the Simulink documentation.

The file containing the block diagram is: C:\Users\Pirouz\Desktop\New folder (2)\New folder (2)\untitled.slx.
