I designed and built an interactive educational control system to teach PID theory and tuning to engineering students. I developed an Arduino Nano-based training platform featuring three potentiometers for real-time P, I, and D parameter adjustment, a 12V geared motor with angular position feedback, and a 16x2 LCD interface for real-time control visualization. The device implements four progressive control modes (Bang-Bang, P-Control, PI-Control, and PID-Control) selectable via push-button switching, allowing students to compare control strategies and observe the practical differences in system response. I designed modular 12V to 5V power management using a buck converter and programmed the embedded control algorithms to demonstrate how each controller type improves system performance and stability.

This section shows the skills I developed/improved working on this project.
Control Theory & Implementation: Deep understanding of Bang-Bang, Proportional, Integral, and Derivative control theories; practical implementation and comparison of how each control method affects system response and stability
Embedded Systems: Arduino Nano programming for PID control algorithms and multi-mode controller implementation
Electronics: Designing power distribution circuits with buck converters and managing multiple voltage rails
System Integration: End-to-end integration of mechanical control knob, motor feedback, microcontroller, and user interface
Documentation & Reporting: Creating educational video content (Arabic/YouTube) to document project functionality and control theory concepts, as well as a project report
