A single-chip microcontroller, also known as a microcontroller, is not a chip designed to achieve a specific logic function, but rather a whole computer system integrated onto a single chip. To put it simply: one chip becomes a computer. It is small in size, light in weight, and inexpensive, providing convenient conditions for learning, application, and development. Moreover, learning to use a microcontroller is the best choice for understanding the principles and structure of a computer.
