Every smart device — from your TV remote to your washing machine — runs on microcontrollers. Learn how they work.

A microcontroller is a small computer on a single chip designed to control electronic devices. It contains a processor, memory, and input/output ports, all packed in one tiny unit.

Popular microcontrollers include the ATmega328 (used in Arduino), STM32, and PIC series. They are the “brains” behind automation systems, robotics, and industrial machines.

Learning microcontrollers opens up countless opportunities to create innovative electronics — from smart sensors to fully automated systems.
