A universal remote is a device designed to control multiple electronic devices, such as televisions, 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 come with pre-programmed codes for popular brands, allowing users to quickly set them up. Some models even feature programmable buttons, enabling customization for specific functions or devices.
