In recent days usability of smart phones and tablets has been rapidly increasing and most of the current smart phones supports Bluetooth LE. So here we proposed an approach to operates the electronic and non-electronic devices by an application in smart phones using Bluetooth LE. The application can manipulate the values of electronic devices such as brightness of light, speed of ceiling fan, lock or unlock doors, windows etc., by simply using the Bluetooth LE. Here we are using iOS device for controls the end device through a PIC designed by us which connected to the end device.
