Remote control systems allow users to operate devices from a distance without physical contact. These systems typically consist of a transmitter, which sends signals, and a receiver, which interprets those signals to perform specific actions. Common applications include controlling televisions, drones, and garage doors. The technology behind remote control systems often uses infrared or radio frequency signals. Infrared remotes require a direct line of sight, while radio frequency remotes can work through obstacles. Examples of devices that utilize remote control systems include TVs, RC cars, and smart home devices.
