How a Microcontroller Works: The Heart of Every Gadget
What actually happens inside an Arduino or an ESP32? Discover how microcontrollers process data, execute code, and control the world around them.
From your microwave to your car's engine, microcontrollers are everywhere. In this video, we move past the "magic" and look at the actual silicon. We cover the simple "Input-Process-Output" loop for beginners and dive into CPU architecture, registers, and memory mapping for advanced learners.
