A universal remote is a device designed to control multiple electronic devices, such as TVs, DVD players, and sound systems, from a single remote. This eliminates the need for several remotes cluttering your living space, making it easier to manage your entertainment setup. These remotes work by sending signals to the devices they control, often using infrared technology. Many universal remotes can be programmed to recognize various brands and models, allowing users to switch between devices seamlessly. Some advanced models even offer features like backlighting and touchscreen interfaces for added convenience.
