Digital controls are systems that use electronic signals to manage and regulate various processes and devices. They replace traditional mechanical controls, offering greater precision and flexibility. For example, in a smart home, digital controls can adjust lighting, heating, and security systems through a smartphone app, making it easier for users to create their desired environment. These controls often rely on sensors and software to monitor conditions and make real-time adjustments. In industries like manufacturing, digital controls help optimize production by automating machinery and ensuring consistent quality. Overall, they enhance efficiency and convenience in both everyday life and complex operations.
