![CONTROL HOME LIGHTS USING SMART PHONE](/proxy/?url=https://content.instructables.com/FZA/S4XU/LIOLP80C/FZAS4XULIOLP80C.jpg&filename=CONTROL HOME LIGHTS USING SMART PHONE)
This project shows how Arduino, Bluetooth and a relay can be used to control home lights or any other AC load in your home.
Supplies
Arduino Uno
HC-05 Bluetooth Module
Relay 5V
A Smartphone
Jumper Wires
Attaching Bluetooth Module to Arduino

HC-05 Bluetooth module is attached to Arduino using jumper wires as follows:
HC-05 RX to Arduino TX
HC-05 TX to Arduino RX
HC-05 Ground to Arduino Ground
HC-05 Vcc to Arduino 5V
The attached connections are shown in photo
Relay AC Load Connection

Remove insulation of power wire of AC Load so that neutral and phase of two wire halves are visible.Cut any one (neutral or phase) into two halves. Now remove insulations from ends of cut portions. Now insert neutral(or phase) of one half into NC of relay and insert neutral(or phase) of other half into COMM of relay as shown in attached photo.

The circuit is completed by attaching Relay Ground to Arduino Ground, Relay IN to Arduino pin 13, and Relay VCC to Arduino 5V.The circuit diagram and completed project are shown in attached photo.
Arduino Program
Arduino program is given in attached file. Before uploading the program, disconnect Bluetooth RX-Arduino TX, and Bluetooth TX-Arduino RX. After program is uploaded, reconnect above mentioned connections.
Downloads
Android App
Android App LED Controller.apk is provided. Install it in your android phone. Pair your smart phone with HC-05 Bluetooth module and use ON/OFF buttons to control AC load.
