A remote control is a component of an electronics device, most commonly a TV, Car door, and Gate originally used for operating the device wirelessly from a short distance. Remote control has continually evolved and advanced over recent years to include Bluetooth connectivity, motion sensor enabled capabilities, internet and voice control.
Commonly, remote controls are Consumer IR devices used to issue commands from a distance to televisions or other consumer electronics such as stereo systems, DVD players and dimmers. Remote controls for these devices are usually small wireless handheld objects with an array of buttons for adjusting various settings such as television channel, track number, and volume. In fact, for the majority of modern devices with this kind of control, the remote control contains all the function controls while the controlled device itself has only a handful of essential primary controls. Most of these remote controls communicate to their respective devices via infrared signals and a few via radio signals. Earlier remote controls in the 1970s used ultrasonictones. The remote control code, and thus the required remote control device, is usually specific to a product line, but there are universal remotes, which emulate the remote control made for most major brand devices.
The main technology used in home remote controls is infrared (IR) light. The signal between a remote control handset and the device it controls consists of pulses of infrared light, which is invisible to the human eye.
Microcontroller
A microcontroller is a single-chip microprocessor system that contains data and program
Memory, serial and parallel input–output, timers, and external and internal interrupts, all Integrated into a single chip. Microcontroller applications are electronic calculators, TV remote controls, digital clocks, washing machines etc.
AIM
The aim of this project is to construct a gate remote control Infrared
