What is Microcontrollern?

A microcontroller is a small, self-contained computer on a single integrated circuit. It contains a processor core, memory (RAM, ROM, or Flash), and programmable input/output peripherals. Microcontrollers are designed for embedded applications to control specific functions in devices such as appliances, power tools, toys, and other embedded systems. They are often used for real-time applications where fast and predictable responses are needed.
