RFID-RC522 Data Reader Multiple Cards With Arduino and Led

Introduction: RFID-RC522 Data Reader Multiple Cards With Arduino and Led

Ok so I will teach you how to make a data reader with arduino and RFID for RFID cards. The data results are shown in the serial monitor.

Step 1: Requirements

-A PC with arduino IDE on it

-2 LEDs

-2 resistors of 220ohm

-An RFID-RC522 reader and cards

-Arduino UNO

-Jumper cables

Step 2: The Electric Part

Assembly the components just like in the sketch!

----------

Connect the + wire to the 3v pin else the circuit will fry!

----------

Step 3: The Code

Just paste the code into a clear arduino IDE file and upload it! Don't forget to check the COM port and board type! Also, look in the code's comments carefully!
