I need a library to make this 28BYJ48 Stepper motor and ULN2003 driver work

Hello to everybody,

I just bought this stepper motor and driver, aparently it doesn’t work with the built in library in Arduino. You need an extra library, I thought I found it:

But when I try to use the implementation, I click on “verify” and I get this error:

C:\Users\santi\Documents\Arduino\libraries\StepperMotor\libreria.cpp:2:26: fatal error: StepperMotor.h: No such file or directory
#include <StepperMotor.h>

I wanted to delete all about the library and start from zero but I cannot find a way to delete the name of the library from the list. I can delete the folder but the name still is present there.

It is a very basic question, Do I need to save the first file ended in .h, and What is its name? What is the name of the file that I have to save as .cpp? Do those names must be equal to the name of the library?

Can’t I remove everything about that library?
