Elevator Control System

This project involves designing and programming a four-floor elevator model using an STM32 NUCLEO embedded board. It focuses on smooth motion control using PID feedback, speed control, and optional IoT integration for data visualization and configuration.

Features

• PID Feedback Control: Ensures precise positioning of the elevator for smooth floor transitions.
• Speed Control: Limits the elevator's speed during motion for safe operation.
• Real-Time Monitoring: Outputs current position and error via a serial interface.
• IoT Dashboard (Optional):
  • Displays elevator position in real-time.
  • Configures system parameters such as maximum speed.
• Multithreading Support: Implements FreeRTOS (optional) to handle I/O and servo control in separate threads for efficiency.
• Customizable Design: Supports additional sensors and advanced functionality modes.

Technologies Used

• Microcontroller: STM32 NUCLEO board.
• Programming Language: C/C++.
• Hardware Components:
  • 3D-printed elevator model.
  • Parallax Feedback 360° servo motor.
  • Break beam sensors for position detection.
  • Safety end-switch for top-floor limit.
• IoT Integration (Optional): ESP32 for real-time data communication.
• Software Tools:
  • STM32CubeIDE.
  • FreeRTOS (optional).
