This project about automatic doorstop and vehicle counters. With the following statement:

1. Vehicle coming

2. The laser light to the photodide is blocked, the photodiode surface darkens

3. On LCD, Total parking increases by 1 and total entry increases by 1

4. The doorstop will open for 7 seconds then closes again

5. Then the vehicle goes into the parking lot

6. Push button pressed

7. LCD displays Exit increases by 1 and total parking decreases 1

8. The doorstop will open for 7 seconds then closes again

9. Vehicle away

A. Electronic Circuit

B. Design sketch

C. Steps to make It

  • Prepare tools according the list
  • Solder all components in the PCB
  • check for errors in the circuit
  • Coding in the Arduino IDE software
  • Run it

EXPANDED TECHNICAL DETAILS

Autonomous Entry Management

This smart gate is designed for professional parking garage automation, integrating vehicle detection and access control.

  • Slot Availability Sensor: Uses an IR Barrier or Ultrasonic sensor at the gate entrance. When a car is detected, the Arduino checks a global "Open Slots" variable.
  • Servo-Driven Actuation: Driven by an MG995 high-torque servo. The Arduino implements a smooth 90-degree sweep for the boom gate, with a deliberate delay to ensure the car has passed before closing.

Interaction Features

  • LCD Status Board: A 20x4 I2C LCD displays messages like "Welcome," "Slots Full," or "Scanning Tag."
  • RFID Integration: can be easily expanded with an RC522 reader to allow only "Monthly Pass" holders to enter automatically.
