How to interface RFID Reader with microcontroller?

RFID Interface with 8051

1. Connect LCD data pins to PORT2 sequentially.
2. Connect LDC RS pin to P1. 5, RW pin to P1. 6, and E to P1. 7 of the microcontroller.
3. RFID TX pin connects to the P3. 0(RXD) of the microcontroller.

Is RFID a microcontroller?

Microcontroller-The microcontroller used in a RFID based attendance system is AT89C52 from the family of 8051. It includes 4-I/O ports and 40-pins.

What is EM 18 Reader module?

EM-18 RFID reader is one of the commonly used RFID reader to read 125KHz tags. It features low cost, low power consumption, small form factor and easy to use. It provides both UART and Wiegand26 output formats. It can be directly interfaced with microcontrollers using UART and with PC using an RS232 converter.

How do I connect RFID RC522 to Arduino Uno?

Wiring – Connecting RC522 RFID module to Arduino UNO To start with, connect VCC pin on the module to 3.3V on the Arduino and GND pin to ground. The pin RST can be connected to any digital pin on the Arduino. In our case, it’s connected to digital pin#5.

How do you make an RFID based attendance system?

How to Operate RFID Based Attendance System Circuit?

1. After making all the above connections, Switch on the circuit.
2. On LCD it is displayed “PLEASE SWIPE THE CARD”.
3. Place the RFID tag near the reader.
4. Reader then reads the data in the tag and transmits to the controller.

What is microcontroller in embedded system?

A microcontroller is a compact integrated circuit designed to govern a specific operation in an embedded system. A typical microcontroller includes a processor, memory and input/output (I/O) peripherals on a single chip.

How does an RFID reader used?

RFID methods utilize radio waves to accomplish this. RFID tags contain an integrated circuit and an antenna, which are used to transmit data to the RFID reader (also called an interrogator). The reader then converts the radio waves to a more usable form of data.

What is RFID attendance system?

Radio Frequency Identification (RFID) based attendance system is one of the solutions to address this problem. This system can be used to take attendance for student in school, college, and university. Students or workers only need to place their ID card on the reader and their attendance will be taken immediately.

What is the use of the RFID module?

Explanation: The RFID Module is primarily used for object identification and tracking. It’s abbreviation stands for Radio Frequency Identification Module. It’s working is mostly wireless and uses electromagnetic fields.

How do I use an RFID code?

Here’s how you do it.

1. On the main screen, select “Basic RFID”.
2. Once the tag has been read, select the EPC number that appears on screen.
3. Then, select “Change EPC”.
4. A screen will pop up with the existing EPC, and you can use your smartphone’s keypad to change the EPC number to whatever you prefer in the character limit.

How to connect RFID reader to PIC microcontroller?

Code for RFID reader interfacing with pic16f877a microcontroller is given below. Code is written in Mikro c for pic compiler. LCD is connect with PORTD to display the rfid tags or card numbers.

Which is microcontroller is used for RFID interfacing?

Here we are using PIC Microcontroller PIC16F877A for interfacing RFID. We will simply read the unique identification no. of RFID tags and display it on 16×2 LCD. In this project, we chose EM-18 RFID module, which is small-sized, low cost, and power efficient module.

How does UART read RFID tag number data?

The UART output provides 12-bit ASCII data. First 10 bits are RFID tag number, which is the unique ID and last two digits are used for error testing. Those last two digits are the XOR of the tag number. EM-18 module will read the data from 125 KHz Passive RFID tags or cards.

How does the em-18 RFID module work?

In this project, we chose EM-18 RFID module, which is small-sized, low cost, and power efficient module. EM-18 RFID module use 125 KHz RF frequency to read passive 125 KHz RFID tags. EM-18 module use Oscillator, demodulator and data decoder to read data from a passive card.
