Abstract

This project presents the design and simulation of an Automated Parking Gate Controller implemented using the Proteus environment. The system utilizes an Arduino Nano as the central processing unit to manage vehicle entry and exit through the integration of two infrared (IR) sensors. When a vehicle is detected at the entry point, the microcontroller triggers a servo motor to actuate the gate arm, while simultaneously incrementing the vehicle count. Conversely, the exit sensor decrements the count. A 16x2 I2C LCD provides real-time visual feedback regarding the current number of parked vehicles. This simulation provides a risk-free, cost-effective platform for students to understand the fundamental principles of sensor-actuator synchronization, interrupt-driven logic, and embedded system prototyping without the immediate need for physical hardware.

Project Description

In urban environments, manual parking management often leads to congestion, human error in vehicle counting, and inefficient entry/exit flows. The Automated Parking Gate Controller is designed to address these challenges by automating the access control mechanism. The primary objective of this project is to create a reliable simulation that mimics a real-world smart parking entrance, focusing on the seamless integration of input sensors and output actuators. The approach involves using an Arduino Nano to monitor two IR sensors placed at the entrance and exit of the parking lot. The system logic is programmed to detect a 'low' signal from the IR sensor when a vehicle breaks the beam, which then triggers the servo motor to rotate to a specific angle (typically 90 degrees) to lift the gate. After a predefined delay, the gate automatically closes. To ensure the parking lot does not exceed its capacity, the system maintains a running total of vehicles, which is displayed on an I2C LCD screen. This eliminates the need for manual ticketing or counting at the gate. From a societal and engineering perspective, this project serves as a proof-of-concept for scalable smart city infrastructure. By moving the development into a simulation environment like Proteus, the project allows for rapid iterative testing of the control logic, ensuring that the timing and synchronization of the gate movements are optimized before moving to physical implementation. It demonstrates how basic embedded components can be combined to solve a common logistical problem, providing a foundation for more advanced systems involving RFID or IoT connectivity.
