I’ve had some problems with setting up my MFRC522 to my arduino. I used the code in one of the libaries but i get a error message that says
: fatal error: MFRC522.h: No such file or directory #include <MFRC522.h>
^
compilation terminated.
exit status 1
Error compiling for board Arduino/Genuino Uno.
I’m afraid this forum is dedicated to the Particle Ecosystem, and as such you’ll be more likely to find more/better assistance on a Arduino oriented forum.
For what it’s worth, it seems that you haven’t included your library files properly, since the compiler can’t find them. Try double checking that.
