Introduction to Universal Remotes

Universal remotes can control multiple devices. They use a single interface to manage TVs, DVD players, and more. Surprisingly, they can emulate the original remotes by storing and transmitting various device codes.

Most universal remotes use infrared (IR) signals. Some advanced models also employ radio frequencies (RF) to control devices through walls. RF remotes can cover a broader range and don't require a direct line of sight.

Many universal remotes have a learning mode. This mode allows them to copy signals from an original remote. By pointing the original remote at the universal remote, you can teach it unique commands not pre-programmed.

Universal remotes come pre-loaded with a vast database of device codes. These codes correspond to various brands and models. Surprisingly, some remotes update their databases via Wi-Fi or USB to support new devices.

Modern universal remotes integrate with smartphones. Using companion apps, you can set up and control devices more easily. Some apps even offer voice control, adding another layer of convenience and functionality.

Some universal remotes can control home automation systems, like lights and thermostats, redefining what a 'remote' can do beyond entertainment devices.
