Embedded Luggage Handling System

An embedded systems project that implements an automated object sorting mechanism using a microcontroller-based control system, motor driver module, and sensor-based detection.

This project demonstrates practical integration of:

• Embedded C / Arduino programming
• Sensor interfacing
• Motor control using PWM
• Hardware system design
• Mechanical structure modeling (3D design)

Project Overview

The Sorting System is designed to:

1. Detect an object placed in the system
2. Identify its category (based on the color)
3. Position the servo motor
4. Drop the object into the correct bin
5. Return to the default position for the next object

The system integrates hardware and software to create a fully functional automated sorting solution.
