multiple rfid readers on one arduino How would I go about expanding this code to include 8 or more RFID readers per arduino? Is that even possible? My old code included a reset pin for the RFID readers.
The non-contact radio frequency IC card is also called MF1 card, the full name is mifare one card. Because the MIFARE ONE PHILIPS IC S50 produced by Philips in the Netherlands has become a similar industry .

By connecting multiple MFRC522 RFID readers to an Arduino Uno, she’s come .
I have problems with multiple RFID (MFRC522) usage. 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 up with a method of triggering a device (like an electronic door lock) only when the appropriate combination of RFID.You could ditch the code for reporting to the serial monitor (so no debugging code and no interaction with the serial monitor on the PC) and only use the LCD for displaying information. Then you can use the free hardware serial port to communicate with one of the RFID readers. I made two differents prototypes using one arduino Uno. One with one RFID reader, one with three different RFID readers. They are both working fine.

rfid with Arduino code
rfid reader Arduino code
These HEX bytes can be deciphered and recreated using an Arduino or other microcontroller if you need a particular capability or feature that is not supported in the SparkFun Simultaneous RFID Reader Arduino library. Security Access using MFRC522 RFID Reader with Arduino. This blog post shows a simple example on how to use the MFRC522 RFID reader. I’ll do a quick overview of the specifications and demonstrate a project example using an Arduino. The Arduino UNO can communicate with an RFID reader to read RFID cards. In this article, we have connected the RC522 RFID reader to the Arduino UNO over SPI. Such RFID readers help build door access, package identifiers, etc.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.
Connecting 20+ RFID readers to Arduino UNO and uniquely identify data read by each reader. Hardware Help. Just to preface this I'm a dense software engineer whose been tinkering with Arduinos for a bit but is still quite the beginner . I have problems with multiple RFID (MFRC522) usage.
