A unique self-contained universal remote control

Universal remote is a controlling device, which can perform all functions of different remotes of various brand appliances that are used in homes. At present, universal remotes do not stand up to their names, as they are not able to control all the devices. The universal remote proposed in this paper is self-contained and brand-independent in that it does not need a receiver unit to be fixed to the device nor does it expect the manufacturers to adhere to a code. The remote stores the code for different appliances in its memory and when a key is pressed retrieves the code from memory and processes it, unlike other remotes, which generate a code, every time a key is pressed.
