Hi I am new to the forum and also pretty new to Arduino and Programming.
Since I started I learned a lot but as a newbie I have my problems.
I recreated a RFID doorlock with my own addons like a display which opens the door to my flat.
I am using a relay to open the door and as I used a dual relay module I also thought it would be a good idea to be able to switch on and of the venting and light in my toilet. Reasons are that I am living in an 250 year old house and power outlets are short, I want to change the lightswitch with an outlet and add a push button on the case I mounted next to the door which houses the arduino and the relays.
I merged the codes and it compiled just fine, but for some reason Iam only able to turn the relay on and off when the RFID is active ( holding the tag to the reader so the electric doorlock opens)
I am not sure whats the problem so I hope you guys can help me, sorry for my bad english.
The whole RFID stuff works like a charm, only the added button switch stuff isnt working as it should.

We need to define MFRC522's pins and create instance
Pin layout should be as follows (on Arduino Uno):
MOSI: Pin 11 / ICSP-4
MISO: Pin 12 / ICSP-1
SCK : Pin 13 / ICSP-3
SS : Pin 10 (Configurable)
RST : Pin 9 (Configurable)
