Description
This RFID modules base on MFRC522 IC and that can read and write Mifare’s tags. The microcontroller and card reader uses SPI for communication. The card reader and the tags communicate using a 13.56MHz electromagnetic field.
Feature:
This RFID modules base on MFRC522 IC and that can read and write Mifare’s tags.
The microcontroller and card reader uses SPI for communication.
The card reader and the tags communicate using a 13.56MHz electromagnetic field.
The RFID MFRC522 module supports MF1xxS20, MF1xxS70 and MF1xxS50 tags.
The RFID MFRC522 module supports contactless communication and uses MIFARE higher transfer speeds up to 848 kBd in both directions.
RFID MFRC522 have compact design and small size 36x36mm.
Power can supply 3.3V or 5V.
This easy for connection to board with 5V, not need power regulator for 3.3V.
The antenna is built into the board. And it has a good sensitivity to a height of 25mm
Getting started with the RFID Reader/Writer NFC module MFRC522 13.56MHz
in this Tutorials we are going to deal with RFID Reader/Writer NFC module this is simple and easy to connect with arduino where going to read the the RFID card target ID and print them to the serial Monitor and you can do different things using this RFID card reader so let’s start
Step1: Hardware required
Step2: Connecting the Hardware
RC522 module Arduino Uno,Nano Arduino Mega
SDA (SS) 10 53
SCK 13 52
MOSI 11 51
MISO 12 50
IRQ Not connected Not connected
GND GND GND
RST 9 9
3.3V 3.3V 3.3V
Step3: Setting up the library
so before readin the RFID card tag we must have the library, so you can download it here. install the library by extracting that zipped file in the library folder as shown below
Step4: Upload the sample sketch
open the sample sketch that is located in file>examples>RFID>cardRead. and upload it. as shown below
Step5: Testing the circuit
open your serial monitor by clicking on the icon in the right top corner(like search icon) slash your card to the RFID reader you will receive the card ID. see the picture below something like that
