Microcontrollers are small computers that are designed to be embedded in larger systems. They are often used to control specific functions within a larger system, such as controlling the operation of a motor or reading data from a sensor. In order to do this, microcontrollers need to be able to communicate with the outside world. This is where input/output (I/O) peripherals come in.

I/O peripherals allow microcontrollers to connect to a variety of devices and sensors. This allows microcontrollers to receive input from the outside world, such as data from a sensor or a button press. Microcontrollers can also use I/O peripherals to output data to the outside world, such as controlling the speed of a motor or displaying data on a screen.

The ability to communicate with the outside world is essential for microcontrollers. Without I/O peripherals, microcontrollers would not be able to perform their intended functions. I/O peripherals are a critical component of microcontrollers, and they play a vital role in the operation of embedded systems.

For example, a microcontroller in a car might use I/O peripherals to connect to the engine, transmission, and brakes.
