RFID RST connection affecting Analog Read

I have a project with a knock sensor reading from an analog pin (it's the basic knock sensor project you can find anywhere). I have an RFID-Rc522 reader connected to the same NANO. As soon as I connect the RFID the analog read seems to be getting values even though I'm not knocking. I can print out the read values and see it "thinks" something is happening on the analog read. I've narrowed it down to happen as soon as I connect the RST pin on the RFID reader to the NANO. I've tried moving the RST connection (which I have a D5) to other digital pins but the same thing happens.

Is there any reason that the RST pin connection would be causing interference to an analog read pin like this?

Why are you posting in Programming? Surely the reason for doing so is some suspicion that the software is an issue. So, where the hell IS your code?

Dude, chill. I accidentally posted this in programming. Don’t blow a fuse.
