Tutorial Rfid Rc522 Arduino. Arduino RFID RC522 Tutorial Roland Pelayo Arduino Tutorial 5 Comments 16653 Views RFID technology has been around for quite a while But it was only recently that hobbyist and makers was able to utilize this technology through the Mifare RC522 RFID mod.
DescriptionSpecificationsLibrary DownloadCircuitDemonstrationRFID means radiofrequency identification RFID uses electromagnetic fields to transfer data over short distances RFID is useful to identify people to make transactions etc You can use an RFID system to open a door For example only the person with the right information on his card is allowed to enter An RFID system uses 1 tagsattached to the object to be identified in this example we have a keychain and an electromagnetic card Each tag has his own identification (UID) 1 twoway radio transmitterreceiver thereader that send a signal to the tag and read its response Input voltage 33VPrice approximately 3$ (check best price on Maker Advisor)Frequency 1356MHz Here’s the library you need for this project 1 Download the RFID library herecreated by miguelbalboa 2 Unzip the RFID library 3 Install the RFID library in your Arduino IDE 4 Restart your Arduino IDE Reading Data from a RFID tag After having the circuit ready go to File > Examples > MFRC522 > DumpInfo and upload the code This code will be available in your Arduino IDE (after installing the RFID library) Then open the serial monitor You should see something like the figure below Approximate the RFID card or the keychain to the reader Let the reader and the tag closer until all the information is displayed This is the information that you can read from the card including the card UID that is highlighted in yel Now upload the code to your Arduino and open the serial monitor Approximate the card you’ve chosen to give access and you’ll see If you approximate another tag with another UID the denial message will show up I hope you found this tutorial useful Share this postwith a friend that also likes electronics!

MFRC522 RFID Reader with Arduino Tutorial Random Nerd Tutorials
RFID modules such as RC522 are used to read and write RFID cards or tags This module works in 1356 MHz frequency and it can write data on tags in addition to read them Here are some of the features of these modules Communicate with microcontrollers using serial SPI and I2C protocols up to 10 Mbit/sec data transfer rate 3V working voltage.

GND pin needs to be connected to GND (0V) VCC pin needs to be connected to VCC (33) RST pin is a pin for reset and powerdown When this pin goes low hard powerdown is enabled On the rising edge the module is reset IRQ pin is an interrupt pin that can alert the microcontroller when RFID tag comes into its vicinity.
