This project implements a Smart Parking Management System using Arduino and various sensors to automate parking space detection and boom barrier control. It provides real-time updates on parking space availability and efficiently manages vehicle entry and exit.
- Parking Space Detection: Utilizes multiple HC-SR04 ultrasonic sensors to monitor the occupancy of three parking spaces.
- Boom Barrier Control: Automates the opening and closing of a boom barrier based on vehicle presence at entry and exit points.
- LCD Display: Shows the number of available parking spaces and which slots are free.
- Serial Monitor Logs: Outputs sensor readings and parking status to the Serial Monitor for debugging and monitoring.
- Compact Design: All components are integrated into a compact system suitable for demonstration and practical use.
- Arduino UNO
- HC-SR04 Ultrasonic Sensors (5 units)
- Servo Motor for boom barrier control
- LCD Display (I2C interface)
- Buzzer for audio alerts (optional)
- Jumper wires, breadboard, and other miscellaneous components
