This project demonstrates a simple RFID Attendance System using an Arduino UNO, RFID-RC522 module, and a 16x2 LCD (I2C Interface). The system reads RFID cards and displays the user information or ...

This project connects a 16x2 or 20x4 LCD Display to an Elegoo Mega 2560, allowing it to display messages or real-time data. The project supports both I2C communication (recommended for fewer wires) ...

Assume that you are moving towards a complex microcontroller project bundled with blinkers, beepers, and a display panel. To link a standard 16×2 LCD directly with the microcontroller, for instance ...

Have you ever noticed how shopping malls, parking lots, or event venues seem to track the number of people or cars present inside? You might think they use an AI camera to count them, but in reality, ...
