Green Bay Packers Championship Seasons: The official source of the .

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. RFID Tag There are . See moreTo make this project we need following items- 1. PIC16F877A 2. 20Mhz Crystal 3. 2pcs 33pF ceramic disc capacitor 4. 16x2 Character LCD 5. A breadboard 6. 10k preset pot 7. 4.7k resistor 8. Single strand wires to connect 9. A 5V adapter 10. RF Module EM-18 11. 5V . See moreAs always, first we need to set the configuration bits in the pic microcontroller, define some macros, including libraries and crystal frequency. You can check code for all those in . See more

The schematic is simple; we connected LCD across port RB and connected the EM-18 module across the UART Rx pin. We have made the . See more

How Does RFID Works? LCD Interfacing; Serial Communication; Why EM18? EM-18 RFID reader is one of the commonly used RFID readers to read 125KHz tags. It features . 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 16x2 LCD. RFID module and its Working. In this project, we chose EM-18 RFID module, which is small-sized, low cost, and power efficient module. How Does RFID Works? LCD Interfacing; Serial Communication; Why EM18? EM-18 RFID reader is one of the commonly used RFID readers 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.

To read the Passive RFID cards and tag, we need a microcontroller with UART hardware. If we select a microcontroller without UART, we need to implement software UART. Here we are using PIC Microcontroller PIC16F877A for interfacing RFID.This system is designed around PIC microcontroller PIC16F877A and RFID Reader RDM6300, which is 125 kHz reader. It also features LCD 1602 display, a buzzer, servo SG90 and a voltage regulating part. EM-18 RFID Reader Module can be directly interfaced with 5V PIC Microcontrollers using UART module. For 3.3V devices you need to add additional voltage divider resistors to reduce 5V to 3.3V. You may also use Software UART if . In this article, interfacing of an RFID reader module has been explained with PIC18F4550. The USART interrupt, an internal PIC interrupt, has also been explained. (For more details on USART, refer PIC EUSART)

EM18 RFID reader module is used to read RFID cards that work at 125 kHz. When an RFID card comes in the range of the reader, the unique data in the card is received by the reader in the form of an RF signal. The reader then transmits this data in byte form on its serial transmit pin.Read and write different types of Radio-Frequency IDentification (RFID) cards on your PIC microcontroller using a RC522 based reader connected via the SOFT Serial Peripheral Interface (SOFT SPI) interface.
