Taking attendance manually consumes more time. So, In this project we have designed RFID Based Attendance System using Arduino and RFID MFRC522 Module. In this system, each student is issued an RFID ...

Arduino Code for RFID-based Authentication System. The code is developed using the Arduino IDE. The EM 18 RFID module operates on serial communication; when RFID is detected, it sends the data over ...

Learn to build an RFID based attendance system using Arduino with step-by-step instructions, circuit diagrams, and complete code. This $35 DIY project replaces expensive commercial systems with ...

Circuit diagram for RFID bassed attendance system project is shown above. In the circuit, LCD is connected in four bit mode with 8051 microcontroller. LCD’s RS, RW and EN pins are directly connected ...

In this study, an attendance system was developed using the Arduino Uno card and RFID technology. This system, which can distinguish between registered and unregistered cards in the course, which ...

Here in this project, you can either use 1 Arduino or 2 Arduino. if you are using 1 Arduino then the SPI and I2C components connect to the Arduino SPI and I2C pins as in the circuit diagram. You can ...

Whenever the card is placed near the reader, it will take the attendance. RFID can be interfaced to microcontroller through USART. Data is transferred from RFID cards to reader and from there to ...

As we discussed before, RFID tags contain a 12 digit unique code and it can be decoded by using an RFID reader. When we swipe the RFID tag near the Reader, the Reader will give the unique codes via ...

In the next section, we will see the circuit diagram for the Arduino-based RFID Door Lock System. RFID Door Lock System using Arduino Circuit Diagram. The below RFID Door Lock System circuit diagram ...
