I just received my RC522 RFID reader and made this simple Arduino access control system that uses the reader, a buzzer for the alarm and a relay shield for the security system. The relay can be used to open a door lock and if you need a louder alarm then you can replace the small buzzer with a high power siren.

1. Welcome

2. Project Presentation Topic:
Student clearance checking system using RFID and Arduino

3. Components In this Project:
• Arduino uno board.
• Bread board.
• RFID-RC522 Sensor.
• Buzzer.
• Jumper cables.

4. What is RFID Reader?
• RFID means radio-frequency identification. RFID uses electromagnetic fields to
transfer data over short distances.
• can use an RFID system to open a door. For example, only the person with the
right information on his card is allowed to enter.

5. Rfid Reader:
• Specifications
• Input voltage: 3.3V
• Frequency: 13.56MHz

6. two-way radio transmitter-
receiver, the reader, that send
a signal to the tag and read its
response.

7. Library , Pin Wiring & Circuit:
• We Need to add RFID Library First to work with this.

8. Working Mechanism:
Id card
Match with
the DB
You are valid

9. Future Plan:
• We can call this project as a prototype project. in future we can
connect it with the database server to store or check data through
internet.

10. Thank You!
