Arduino Car Parking System

Overview

This project implements a simple car parking system using Arduino, IR sensors, a servo motor, and an LCD display. It monitors the availability of parking slots and controls access using the servo motor.

Components Used

• Arduino Uno
• 2x IR Sensors
• Servo Motor
• LCD Display (16x2 characters) with I2C module

Libraries Used

• Wire.h (for I2C communication with the LCD)
• LiquidCrystal_I2C.h (for controlling the LCD)

Hardware Setup

1. Arduino Connections:

   • Connect IR Sensor 1 to Digital Pin 4.
   • Connect IR Sensor 2 to Digital Pin 6.
   • Connect Servo Motor to Digital Pin 9.
   • Connect SDA pin of the I2C LCD Display to A4 on Arduino.
   • Connect SCL pin of the I2C LCD Display to A5 on Arduino.

2. Power Supply:

   • Power the Arduino board using a USB cable connected to your computer or an external power supply.

3. Assembly:

   • Mount IR sensors in a position where they can detect incoming and outgoing cars.
   • Attach the servo motor to control the parking barrier.

Software Setup

1. Arduino IDE:

   • Download and install the Arduino IDE from arduino.cc.

2. Install Libraries:

   • Open the Arduino IDE.
   • Navigate to Sketch > Include Library > Manage Libraries....
   • In the Library Manager, search for LiquidCrystal_I2C by John Rickman.
   • Click Install to install the library.

   If you encounter an error during installation, you can manually download the library

   • Extract the downloaded ZIP file into your Arduino libraries directory (usually found in Documents/Arduino/libraries/).

3. Upload Code:

   • Open the Arduino_Uno_file.ino sketch provided in this repository.
   • Verify and upload the sketch to your Arduino board (select correct board and port under Tools menu).

Usage

1. Upon startup, the LCD will display a welcome message.
2. IR sensors detect incoming and outgoing cars:
   • IR Sensor 1 manages incoming cars.
   • IR Sensor 2 manages outgoing cars.
3. The system dynamically updates the number of available parking slots on the LCD.
4. When all slots are full, the LCD displays a "Parking Full" message.
5. The servo motor controls the barrier to allow or deny access based on slot availability.

Troubleshooting

• If you encounter issues with the LCD display or servo motor, ensure all connections are secure and configured correctly.
• Check the Arduino IDE serial monitor for debugging messages if needed.
