NFC tags and readers communicate wirelessly with each other over very short distances. Tags store a small amount of data on them that is sent to the reader in the form of electromagnetic pulses.
I use the MFRC522.h library from GitHub - miguelbalboa/rfid: Arduino RFID Library for MFRC522, and I want to read 8 RFID modules with one Arduino Uno, but I have managed only 2! I connect all the SPI pins, SS1 to pin10 and SS2 to pin2. By connecting multiple MFRC522 RFID readers to an Arduino Uno, she’s come .

By connecting multiple MFRC522 RFID readers to an Arduino Uno, she’s come up with a method of triggering a device (like an electronic door lock) only when the appropriate combination of. You can connect at least 4 ID2s each to their own hardware serial line. If you can be sure that no two readers will read a tag at the same time, then it might be feasible to use some OR/AND gates to OR/AND together the serial TX lines from a number of ID2s and feed it to a single RX line on the ATMega2560.
I’m making a simple door lock for my room using an Arduino uno and an RFID sensor, I made the code to unlock the door with the correct tag, but it’s only on one side, I need a way to unlock the door from the other side as well, could I connect another sensor to the same pins on the Arduino since only one would be used at a time?
I am trying to use the RFID-RC522 modules for an escape room idea. I am using the MC522 Library and the SPI library to read the readers and then switch a relay. Every time I try and connect one reader to the arduino, it works perfectly.
rfid reader Arduino code
You could ditch the Uno and buy an Arduino Mega, which has 4 hardware serial ports. Then you can connect both RFID readers to hardware serial interfaces, using the first serial interface for communication with the PC and still having one interface left. This would be my preferred way.
This blog post shows how to use the MFRC522 RFID reader. I'll do a quick overview of the specifications and demonstrate a project example using an Arduino. Step-By-Step Instructions To Connect The RFID RC422 With Arduino UNO. In this section, we will build a project using Arduino UNO and the RFID Reader module RC422. The RC422 supports SPI and I2C protocols to communicate with .
Learn how to use RFID NFC RC522 with Arduino, how to connect RFID-RC522 module to Arduino, how to code for RFID/NFC, how to program Arduino step by step. The detail instruction, code, wiring diagram, video tutorial, line-by-line code explanation are provided to help you quickly get started with Arduino. Find this and other Arduino tutorials on .Is it possible to connect multiple RFID-RC522 readers to the same 3.3V, RST, GND, IRQ, MISO, MOSI and SCK pins if you use a different pin for each SDA? If so, this would save me a lot of pins. So far, I have only seen direction on how to connect one RFID-RC522 to an Arduino.
