This project consists of building a universal remote controller, which can be used to control any kind of device capable of communicating its user interface. The remote device works based on an infrared technology and allows the user to control any of the home appliances. The idea and design of this project are considered as a multicommunication between transmitter and receiver, because the remote control device combines many remotes into one and has an ability to control up to fifteen appliances that are commonly used at homes. Thetransmitter contains 15 independent inputs and has a carrier wave frequency of 38 kHz, which is the same for almost all infrared remote controls. Similarly, the receiver has 15 independent outputs, each of which can operate separately. The SAA3004 transmitter integrated circuit (IC), which is designed for infrared remote control systems, is used as a main IC on the remote control itself. As for receiver part, PIC16C55-XT/P is used as a microcontroller to control the infrared receiver operations due to the increased number of Input/Output pins. Both ICs are programmed accordingly to provide a multi- communication. A desktop lamp and fan are used as the example appliances to be remotely controlled. The control of these appliances is associated with ON/OFF switching application. Since a remote control has become a part of the everyday life, in this project, an infrared remote control system is designed to prove the universality of it.
