Microcontrollers

Microcontrollers are compact integrated circuits designed to control specific functions in embedded systems, combining a processor, memory, and input/output peripherals on a single chip. They are widely used in devices like home appliances, automotive systems, and IoT gadgets to execute dedicated tasks with low power consumption and real-time responsiveness.

Also known as: MCU, Microcontroller Unit, Embedded Controller, Single-Chip Computer, uC

Why learn Microcontrollers?

Developers should learn microcontrollers for building embedded systems, IoT devices, robotics, and automation projects where cost, size, and power efficiency are critical. They are essential for applications requiring direct hardware control, such as sensor data processing, motor control, and real-time monitoring in industrial or consumer electronics.
