A microcontroller is a small and self-contained computer on a single integrated circuit (IC) chip. It includes a CPU (Central Processing Unit), RAM (Random Access Memory), ROM (Read-Only Memory), and various I/O (Input/Output) peripherals such as timers, serial communication interfaces, analog-to-digital converters, and digital I/O pins. Microcontrollers are designed to perform specific tasks in embedded systems, where they control and manage various functions and devices in real-time.
