Microcontrollers are small computing devices that can control various electronic systems. They are widely used in everyday applications such as home appliances, automotive systems, and medical devices. For example, a microcontroller in a washing machine can manage different cycles and settings, ensuring efficient operation. In addition to consumer products, microcontrollers play a crucial role in industrial automation and robotics. They can be programmed to monitor sensors and control machinery, enhancing productivity and safety. Applications in smart home technology also utilize microcontrollers to automate lighting, heating, and security systems, making homes more efficient and user-friendly.
