Abstract: So far we are controlling many electrical devices at homes, colleges, offices, institutions manually. To control all electrical devices we need a lot of “MAN POWER”. If manpower increases maintenance cost also rises. This doesn’t cause any benefit to the college. So to avoid these kinds of drawbacks we need some wireless controlling systems. This communication system can be used in all fields like industry, domestic purposes like home appliances controlling using sensor or voice command as a remote. This system can be used by elder or disable persons who are unable to go to the switchboard to control the devices. Remote operation is using smart phones or devices with Android operating system, upon a GUI (Graphical User Interface) based voice command. This Arduino based voice controlled college appliances using Wi-Fi uses the android application that sends voice command to the devices through the Wi-Fi. This system reduces human labour, effort, time and errors due to human negligence. We can control all loads at a time from one place without connecting any physical wire between loads and control room.
