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 ...

Fig. 1 shows the circuit of RFID based access control using Arduino board. The circuit is built around Arduino UNO board (Board1), RFID reader module (RFID1), solenoid lock and a few other components.

I just received my RC522 RFID reader and made this simple Arduino access control system that uses the reader, a buzzer for the alarm and a relay shield for the security system. The relay can be used ...

Now that the hardware is ready lets move on to the programming section of our rfid door locking system. But before we do that its important to understadn that the Arduino code for this project is ...

This project implements an RFID-based access control system using an Arduino board, an MFRC522 RFID reader, an I2C LCD display, an RTC (Real-Time Clock) module, and indicator LEDs with a buzzer. It ...

It also allows power to be distributed to various devices by connecting the power pin and GND pin of the Arduino board to the positive and negative rows of the breadboard, providing a shared power ...

This project aims to develop a warehouse security system using an ESP32CAM, keypad, and Arduino UNO, LCD. The ESP32CAM is a powerful microcontroller that integrates Wi-Fi and a camera module, making ...
