Home Automation Via Bluetooth by Phone With Arduino



About: hey, this is Neel. and i like to play with electronics to make world better place.

First of all I made my own script to control the relays but for that i have to use the terminal to type the commands and 2nd option is the voice control but its not working accurately.So i i ifound arduino to bluetooth app which is very good and easy to operate.In this project i have used 4 channel relay module so i can control the 4 things for my phone but app can handle up to 8 channel.I have used HC-05 bluetooth module and arduino pro mini
