“Nowadays, people have smartphones with them all the time. So it makes sense to use these to control home appliances. Presented here is a home automation system using a simple Android app, which you can use to control electrical appliances with clicks and voice command. Commands are sent via Bluetooth(HC05) to Arduino Uno, Which controls the relay operation( ON or OFF). So you need not get up to switch on or switch off the device while watching a movie or doing some work and other reasons.”
