A microcontroller is a small-sized computer chip, which includes a computer's central processing unit (CPU), memory (RAM, ROM, EEPROM, etc.), digital/analog input/output devices, etc. in a single chip.
As an electronic component, a microcontroller is programmable, capable of communicating with peripherals, and capable of performing various signal processing, control, and data processing functions.
These features are used in various fields such as automobiles, home appliances, industrial robots, and medical equipment.
Microcontrollers are used in small-scale projects to large-scale products, and are especially important for products related to embedded systems.
In addition, it is used in development boards such as Arduino and used in various projects.
Microcontrollers are becoming more integrated due to recent technological advancements, and play an important role in IoT devices that can operate while connected to the Internet.
