Microcontrollers are small computers on a single integrated circuit, containing a processor, memory, and input/output peripherals. They are widely used in embedded systems for performing specific control functions efficiently. Applications of microcontrollers include robotics, IoT, and home automation. Popular examples include Arduino, ESP32, and Raspberry Pi Pico.
