This session introduces PID(Proportional-Integral-Derivative) control — the algorithm behind how robots, drones, and everyday devices like ACs and 3D printers stay stable and precise. We'll break down how each term works using simple, intuitive examples, then move into a live demo where a real robot gets tuned in real time — watch it go from wobbly to smooth as gains are adjusted on screen. No prior control theory needed, just curiosity about how machines "think" and correct themselves. Great for anyone into robotics, embedded systems, or electronics
