voice controlled home automation using arduino Hello Friends! During this project, we’ve got designed a Voice Activated Home Automation system, wherever totally different appliances square measure controlled by causing a Voice Command. The Voice Activated Home Automation project is enforced victimization Arduino UNO, Bluetooth and a sensible phone. Any sections can make a case for circuit diagram, elements needed and dealing of the project. [otw_is sidebar=otw-sidebar-1]

Voice Controlled Home Automation Using Arduino Code

The conception of Home Automation is gaining quality because it helps in reducing human effort and errors and so increasing the potency. With the assistance of Home Automation system, we are able to management totally different appliances like lights, fans, TV, AC etc. in addition, a home automation system may also offer different options like security, and alarms, emergency systems etc. will be integrated. There square measure many sorts of Home Automation Systems like Bluetooth Controlled, web Controlled, RF Controlled, Remote Controlled etc. every kind has its own blessings and disadvantage.

Components Required


  • Arduino
  • Bluetooth Module
  • NPN semiconductor
  • Resistor
  • PN Junction Diode
  • Smart Phone
  • Motor
  • LED


Circuit Design

We will currently see the planning of the Voice Activated Home Automation circuit. First, we are going to connect the Bluetooth Module to the Arduino. Since Bluetooth uses UART protocol, we want to use the RX and Lone-Star State pins of the Arduino. We are going to be victimization “Software Serial” library to outline our own RX and Lone-Star State pins. Next, we are going to connect the relays to the Arduino. Since we tend to use a readymade relay board with four channels, all we want to try and do is to attach the inputs of the individual relays to the Arduino. For elaborated affiliation just like the electrical device, transistor, diode and relay, refer the circuit diagram.


In this project, a straightforward Voice Activated Home Automation system is intended. Voice commands square measure accustomed management totally different appliances. We are going to currently see the operating of the project. All the connections square measure created as per the circuit diagram higher than. After creating the required connections, we’ve got to modify on the facility provide to the circuit. Now, we want to combine the Phone’s Bluetooth to the Bluetooth Module. Before that, we’ve got to put in the App mentioned higher than within the phone. Next step is to attach the phone with the Bluetooth module. For this, select the choice Connect Robot and choose the suitable Bluetooth Device. If the devices aren’t paired earlier, we want to combine them currently victimization the Pin of the Bluetooth Module. After eminent affiliation, the devices square measure able to transmit knowledge. For that, press the press electro-acoustic transducer icon on the app and begin giving voice commands.


  • The Voice Activated Home Automation system can facilitate United States management totally different hundreds (electrical appliances) with straightforward voice commands.
  • This quite system is incredibly helpful for folks with disabilities.
  • Further, the project will be distended by adding totally different sensors.


I hope you are thinking that regarding this guide helpful. Can meets you guys next time. Until then lookout, have any fun.
