- Gathering Components: First, I gathered the necessary components, including an Arduino Uno, an RFID reader module, an RFID card or tag, a servo motor, and connecting wires.
- Connections: I connected the RFID reader module to the Arduino Uno using jumper wires, ensuring proper pin connections according to the module's specifications. Then, I connected the servo motor to the Arduino Uno to control the locking mechanism.
- Programming Arduino: Next, I wrote the Arduino code to initialize the RFID reader and servo motor, defining functions to read RFID card IDs and control the servo motor based on authentication.
- RFID Authentication: In the code, I programmed the Arduino to compare the RFID card ID scanned by the reader with a predefined list of authorized IDs. If a match is found, the servo motor unlocks the door.
- Testing and Debugging: I tested the system thoroughly, scanning different RFID cards to ensure proper authentication and door unlocking. I also debugged any issues encountered during testing, refining the code as needed.
- Integration: Finally, I integrated the system, ensuring the servo motor effectively locks and unlocks the door in response to valid RFID card scans, completing the RFID Door Lock system project.
