Hello all,

I am very new to arduino and all this stuff. This rfid garage opener ist exactly what i am lookibg for as my first project. But i have problems compiling the code with arduino ide. I get error notifications regarding the .h files. Do I have to include them in my arduino ide folders? Can someone please tell me where to find them? And where i have to save them?

It would be very nice if someone helps me!

Thanks
