Summary of PIC16F88 SN75176 CCS C EM4100 RF-ID READER PROJECT
This article describes an educational RFID reader project using a PIC16F88 microcontroller to read 125KHz EM4100 cards. The system communicates via RS232, providing visual and audio feedback (LEDs, buzzer) and activating a relay for one second upon successful verification. It includes a PC interface built with Delphi 7 and utilizes the SN75176 chip for communication conversion.
Parts used in the PIC16F88 EM4100 RF-ID Reader Project:
- PIC16F88 Microcontroller
- EM4100 RFID Card/Reader Module
- SN75176 Chip
- Green LED
- Red LED
- Buzzer
- Relay
- PC with Delphi 7 Software
- CCS C Compiler

Hi friends I have done with you I share a RF-id application. Application for educational purposes only and is exemplary and is capable of being improved. If we are talking PIC16F88 application is used as a controller. Located in the market comfortable with PIC16F88 PIC16F628 16F628 not much difference in price than `is a handy controller.
RF-ID CIRCUIT DIAGRAM
The so-called circuit 125KHz EM4100 RF-ID card read read and sends the data series. RS485 communication circuit on the printed circuit are wanting to cancel and use it as RS232. Read circuit for 5 seconds after you send the card information, waits for information from the answer the answer is ‘E’ green LED light buzzer and relay runs for 1 second. A different answer or a reply is not received for 5 seconds to cut the red LED and buzzer twice as warning. There are two LEDs on the circuit buzzer and relay.
Also read on your pc and send a reply to the received code with delphi 7 I made a small interface circuit can test it. CCS is written in C code for PIC16F88.
Finally, the on-board RFID reader module is a module for microelectronics. Domestic or abroad, can be obtained. En EM4095 chip on the module. Wishing to be helpful.

-
What is the primary purpose of this application?
The application is designed for educational purposes only and serves as an exemplary model capable of improvement. -
Which microcontroller is used as the controller in this project?
The PIC16F88 is used as the controller, though the PIC16F628 is noted as a price-competitive alternative. -
How does the circuit handle successful card reading?
Upon receiving the correct data, it waits five seconds, then turns on the green LED, activates the buzzer, and runs the relay for one second. -
What happens if the circuit does not receive a reply within five seconds?
The red LED lights up and the buzzer sounds twice as a warning signal. -
What software was used to create the PC interface for testing?
A small interface circuit was created using Delphi 7 to read on the PC and send replies to the received code. -
Which programming language is used for the PIC16F88 code?
The code for the PIC16F88 is written in CCS C. -
Can the RS485 communication circuit be modified?
Yes, the printed circuit originally intended for RS485 can be cancelled and used as RS232 instead. -
Where can the on-board RFID reader module be obtained?
The module containing the EM4095 chip can be obtained domestically or abroad.
