How Remote Controls Work

Remote controls operate devices wirelessly using electromagnetic waves, primarily infrared radiation. Infrared is an invisible light emitted by an LED in the remote, detected by a device's sensor. When a button is pressed, the remote sends a binary code via infrared pulses, instructing the device to perform specific functions. Each remote is designed to control only its intended device, ensuring functionality specificity.
