In modern society, home and office automation become increasingly important and interesting. They not only provide better ways to transfer information within homes/offices and between homes/offices, they provide better time management too. These also improve the quality of our lives by automating some of the electrical home appliances such as light source, A/V equipment, computer, security device, etc. The paper describes a hardware-based remote controller for power point control. Users can input the control commands and their own passcodes by using local or external telephones. The paper also discusses the operational sequence of the remote controller.>
