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 ...
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 ...
The following project demonstrates "A Real-Time Digital Clock" built using Arduino Uno R3, a 16x2 LCD display, and push buttons—no RTC module required. The project uses Arduino’s internal timing and ...
