What are microcontrollers?

Microcontrollers are compact integrated circuits (ICs) that serve as the "brains" of various electronic devices, controlling their functions and processes. They combine a central processing unit (CPU), memory, input/output ports, and other essential components on a single chip. Microcontrollers are commonly used in everyday devices such as smartphones, appliances, vehicles, and even wearable technology.

They also provide the intelligence, processing power, and connectivity necessary to transform ordinary objects into smart, connected devices that contribute to the Internet of Things (IoT) ecosystem. As this technology becomes increasingly integrated into our lives, understanding microcontrollers allows you to create connected devices that communicate and interact with each other through the internet.
