Here’s a project that integrates an RFID reader, a servo motor, an LCD, 3 LEDs, and a 2-pin piezo buzzer with Arduino. This setup can be used to create an access control system where the RFID reader ...

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 ...

This project demonstrates an RFID card reader system using an Arduino microcontroller, an OLED display (SSD1306), an RFID module (MFRC522), and a servo motor. When an RFID card is scanned, the system ...

For this, we would need a solar tracker. So, in this project, we would make an inexpensive but effective solar tracker prototype using an Arduino. two LDRs are used to detect the light intensity.
