LCD-RFID Esp32 box

This project is an RFID-controlled smart relay system powered by the ESP32 microcontroller. It features an MFRC522 RFID reader and a 16x2 I2C LCD display to provide interactive feedback to the user. Authorized RFID cards can toggle a connected relay ON or OFF, making it suitable for controlling power to devices, access gates, or other electronics. The LCD displays real-time information such as card ID, user name, access status, and current power state. The entire system is housed in a custom-designed 3D-printed enclosure consisting of two pieces: the main body, which contains the electronics, and a snap-fit back panel for easy assembly and maintenance. This design makes the device both secure and user-friendly for smart home or DIY automation projects.
