1. Overview of Automatic Car Parking System Using Arduino

An automatic car parking system is a smart solution that minimizes human intervention by automating vehicle parking. This project demonstrates an intelligent system that detects the presence of vehicles, manages parking slots, and displays the availability status on an LCD screen. It also controls the barrier gate using a servo motor to allow or deny entry based on the parking slot status.

2. Components Required

To build this automatic car parking system using Arduino, you will need the following components:

• Arduino UNO – The microcontroller that processes the data.
• IR Sensors (2x) – Used to detect the presence of vehicles.
• Servo Motor – Controls the parking barrier.
• LCD Display (I2C) – Shows the parking status.
• SMPS (Switched Mode Power Supply) – Provides power to the system.
• Connecting Wires – For circuit connections.

Each component plays a crucial role in ensuring the system’s efficiency.

3. Working Principle

The Automatic Car Parking System Using Arduino operates as follows:

1. 1. 1. Vehicle Detection: IR sensors detect whether a car is approaching or leaving the parking area.
      2. Slot Availability: The system checks if a parking slot is available.
      3. Gate Control: If a slot is available, the servo motor opens the barrier.
      4. LCD Display Update: The number of available slots is updated and displayed.
      5. Exit Detection: When a car exits, the available slot count is updated.

This ensures automated and hassle-free parking management.

4. Circuit Diagram & Connection

The circuit diagram below illustrates how the components are connected.

Connections:

• IR Sensors → Arduino Digital Pins
• Servo Motor → Arduino PWM Pin
• LCD I2C → Arduino I2C Pins (SDA & SCL)
• SMPS Power → Arduino & Other Components

5. Arduino Code Explanation

Below is a simple Arduino code for this project.

#include <Servo.h>
#include <Wire.h>
#include <LiquidCrystal_I2C.h>

Servo gate;
LiquidCrystal_I2C lcd(0x27, 16, 2);

int irSensor1 = 2;
int irSensor2 = 3;
int slotCount = 1;

void setup() {
    pinMode(irSensor1, INPUT);
    pinMode(irSensor2, INPUT);
    gate.attach(9);
    lcd.begin();
    lcd.backlight();
    lcd.setCursor(0, 0);
    lcd.print("Parking System");
    lcd.setCursor(0, 1);
    lcd.print("Slots Available: ");
    lcd.print(slotCount);
}

void loop() {
    if (digitalRead(irSensor1) == LOW && slotCount > 0) {
        slotCount--;
        gate.write(90);
        delay(2000);
        gate.write(0);
        lcd.setCursor(0, 1);
        lcd.print("Slots Available: ");
        lcd.print(slotCount);
    }
    if (digitalRead(irSensor2) == LOW) {
        slotCount++;
        lcd.setCursor(0, 1);
        lcd.print("Slots Available: ");
        lcd.print(slotCount);
    }
}

This code ensures that the system detects vehicles, controls the barrier gate, and updates the parking slot status in real-time.
