Project Summary

This project involves developing an Elevator System using Qt Creator for software and Arduino, Stepper Motors, and LEDs for hardware. The system includes two elevators serving a four-story building, with call buttons outside and floor selection buttons inside. The software generates random floor requests. The system follows Object-Oriented Analysis and Design (OOAD) principles using UML and employs a multi-tier architecture:

• GUI Tier: Represents elevator buttons using Qt Forms, available both inside and outside the elevators.
• Controller Tier: Manages hardware, processes user requests, and tracks real-time data such as distance traveled since the last maintenance.
• Hardware & Server Tier: Uses microcontrollers to control stepper motors and LEDs for elevator operation, while an SQLite database stores user requests, timestamps, and distance data.
