📘 Introduction to Microcontrollers and Embedded Systems

A microcontroller (MCU) is a compact integrated circuit designed to govern a specific operation in an embedded system. It typically includes a processor (CPU), memory (RAM, ROM, Flash), input/output peripherals, and timers – all in a single chip. Microcontrollers are considered the "brains" of embedded systems.

An embedded system is a combination of hardware and software designed to perform a dedicated function. Unlike general-purpose computers, embedded systems are optimized for efficiency, cost, and reliability. They are everywhere – from your washing machine and mobile phone to cars, airplanes, and medical devices.

🔎 Importance of Case Studies in Microcontrollers & Embedded Systems

Why focus on case studies?
Because theory alone cannot showcase the real-world value of microcontrollers. Case studies:

Provide practical knowledge of hardware-software co-design.

Illustrate how microcontrollers solve domain-specific problems.

Highlight the trade-offs in power, performance, and cost.

Show industry use-cases like IoT devices, automotive controllers, drones, and smart healthcare.

Inspire students and researchers to innovate beyond textbooks.
