Why is the NFR24 needed at all?

Hello all,

Thanks for your answers! Yesterday I could finish the uploading to the arduino nano. Now I wanted to test the garage opener and did the connections like in the picture at the top of this. But nothing is hapening 😞 Even the red light led ist not on. Do I have to "start" the programm some how?

Thanks for your help!

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
