Circuit connections of this project are very simple. Bluetooth module’s Rx and Tx pins are directly connected to the Tx and Rx pins of Microcontroller. Three 5 volt relays are used as a switch for turning On and Off the home appliances running on AC mains. And a relay driver ULN2003 is used for driving relays. Fan, Light and TV are connected at P2.1, P2.2 and P2.3 via relays and relay driver. An 11.0592 MHz Crystal oscillator is used in this circuit for generating clock signal for microcontroller. And a 5 volt voltage regulator LM7805 is used for provide 5 volt for the whole circuit.-Circuit connections of this project are very simple.
