Smart Parking System

A real-time parking management system designed using Arduino UNO, IR sensors, LCD Display with I2C module, and Servo motor. It detects parking slot occupancy, automates gate control, and displays availability status, helping drivers find parking slots faster and reducing urban traffic congestion.

📜 Project Overview

The Smart Parking System addresses common parking challenges such as traffic congestion, inefficient parking space usage, and user frustration.
This system automates:

• Real-time slot detection
• Automated gate access
• Slot status updates on LCD display

It is ideal for small to medium-scale parking facilities like shopping malls, offices, and urban centers.
