i am new in coding for arduino. I need some help with the project i'm working on. my project is a object tracking by using the rfid rc522 for inventory system. so i need to have multi reader in this project. i would like to have 4 reder that will work at the same time. this is how i want my project to work: 1. there is going to be 3 or 4 reader rc522, 1 i2s lec and leds. 2. one rfid tag will be use as the master card. the master card have the ability to add or remove card. 3. when 1 tag is tapped on 1 reader, the card quantity at the reader that it tapped will increase. example when we tap the tag at reader1, reader1 will add 1 card into its memory.

I'm new to house building and I need some help with a project. I'm building a house with 3 bedrooms and a basement suite.MFRC522library to interface with the RFID reader. Is that working? If not: How exactly is it not working? What did you expect and what actually happens? Are the examples working, that normally come with such a library? Or is the problem, that you don't know how to extent the code?
