Microcontrollers
A microcontroller is a small, low-cost computer-on-a-chip that can be used to control electronic devices and systems. It consists of a central processing unit (CPU), memory, input/output (I/O) ports, and other peripherals integrated onto a single chip. Microcontrollers are commonly used in a wide range of applications, including automotive systems, home appliances, industrial automation, and consumer electronics. One of the key benefits of microcontrollers is their ability to interact with their environment through sensors and actuators, making them well-suited for use in embedded systems. These systems are often found in devices that require real-time control or data processing, such as medical equipment, aircraft, and factory automation systems.
