A comprehensive collection of Arduino experiments and foundational electronics exercises that formed my pathway into robotics. Structured like a personal lab notebook, this project documents my journey through sensors, actuators, serial communication, and control logic—all essential components for building robots. Each folder represents a focused micro-project or concept demo that helped me understand how robots perceive their environment, process information, and interact with the physical world.
