Turnstile Access Control System Using RFID, Stepper Motor, IR Sensor and Arduino Uno

Arduino serves as the project's microprocessor. RFID is used to read student cards and tags; if the tag or student card is correct, the turnstile, which is a stepper motor, will spin 90 degrees, granting entrance to the individual leaving the premises. However, if the tag or student card used is not allowed, the turnstile will not open to allow entry. For someone to enter the premises, the IR sensor must first identify the presence of someone at the turnstile's entrance site, and if that person uses an approved tag or student card, the turnstile will turn 90 degrees to permit access.

• Arduino Uno
• Jumper wires (male/male and male/female)
• Mini breadboard
• RFID module (MFRC-522)
• Card & Tag
• Stepper Motor (28BYJ-48) with ULN2003 Driver board
• IR Sensor
• cardboard
• Hot glue & gun

After gathering all the materials needed, you may start connecting the circuit as shown on the schematic. All the pins must be connected correctly and accurately.

Download the code and upload it to the microprocessor (Arduino).
