Likewise, the green and blue bulbs will be controlled similarly with commands ‘blue on’, ‘blue off’, ‘green on’ and ‘green off’. In this Arduino project, we will create a home automation system that will control home appliances via HC-05 Bluetooth and an Android application. HC-05 Bluetooth will be used to communicate with Arduino using an Android Application known as the S2 Terminal.There are also other apps but this is free and easy to use. To establish a Bluetooth connection, we will use the HC-05 Bluetooth module. When we pressed any button of the App, the App sends a unique load value according to the button. The HC-05 Bluetooth Module received this unique load value and send it to the Arduino.
If the command ‘all off’ was sent, then all the bulbs will turn OFF. Likewise, if the command ‘white on’ was sent, then the white bulb will turn ON. If the command ‘white off’ was sent, then the white bulb will turn OFF.
Apps and online services
You can pair your phone with the HC-05 Bluetooth Module like we normally pair the phone with Bluetooth earphones or speakers. If your smartphone pair with the HC-05 Bluetooth module, then you can see the “HC-05 Bluetooth” name on the top side of the App and select it. This Arduino UNO consisting of a microcontroller namely ATMEGA328. It has both analog and digital I/O pins inorder to communicate with the external peripherals. Arduino based device control using Bluetooth on Smartphone project can be enhanced to control the speed of the fan or volume of the buzzer etc.
Very compact design can fit in small area, manly this board is made for low voltage application. In the system, we have a mobile app which can be an MIT-app invented app or You can also download the app from the play store with the name home automation. There are many apps you can download the app as per your requirement We will also share the link below.

This project is one of the important Arduino Projects. Arduino based home automation using Bluetooth project helps the user to control any electronic device using Device Control app on their Android Smartphone. The android app sends commands to the controller — Arduino, through wireless communication, namely, Bluetooth. The Arduino is connected to the main PCB which has five relays as shown in the block diagram. These relays can be connected to different electronic devices like lights, television, fan, etc. Of technologies influence us to use smartphones to remotely control the home appliances.
In the demonstration, we have used DC Fan and DC Bulb. To drive this DC Fan and Light, a 9V battery is connected. Moreover, set the value of the pins connected with the three bulbs to HIGH by using digitalWrite() function. Specify the pin as the first parameter and the value as the second parameter. This will ensure that all the bulbs are off initially. Next, we declare the Arduino pins that are connected with the LCD.
Configuration of Different Sensors
Home automation using voice control can help disabled persons use appliances with ease. Any android phone can be used, no internet required once the app is downloaded. 5) Relays to control devices – We have used 12volt Single push single throw relays. I had built a basic Bluetooth based app that just sends the information to the Bluetooth controller. When the user presses on the ‘On’ button displayed on the app for the device 1, the Buzzer is switched on.
Any person can use Voice Controlled Home Automation using Arduino project to control any electronic appliance in their home, shop, or industry. This can be done by an app on his/her Android Smartphone. We have interfaced the Arduino with the main circuit. The user can connect relays to various electronic home appliances. You can see in the block diagram below that Device 1 is Fan, Device 2 is Light and Device 3 is Buzzer.
2) Bluetooth receiver module – Our project will be connected to the smartphone using Bluetooth technology. Configure the pins connected with the bulbs and the TX pin as output pins and the RX pin as an input pin. Specify the pin as the first parameter and the mode as the second parameter. ELECTRODUINO.COM is a free online platform, it provides A Better Way to Learn Electronics.
Now considering room scenario, an Arduino UNO will control devices and reads sensor data. The figure "Room Architecture" depicts how the Arduino UNO will connects with the devices and sensors. Room have multiple controllable devices(i.e. Light, Fan, Wall Socket, etc.), one PassiveIR , one temperature sensor and LDR .
Similarly, when the user says ‘2’ on the app, Device 2, i.e. the Buzzer is switched on. Whenever the user says ‘1’ on the app, Device 1, i.e. the Fan is switched on. 4) LCD Display – The Liquid Crystal Display is optional but shows important messages like device status once command is received from Bluetooth. Home automation and Device control can be done using the Internet of Things — IOT technology. In this research work two software Arduino Integrated Development Environment and Bluetooth terminal application are used.
Clipping is a handy way to collect important slides you want to go back to later. Now customize the name of a clipboard to store your clips. Arduino Based Home automation project report using Bluetooth and Android Device. Needs to review the security of your connection before proceeding. The Internet is not required for using this project. An LCD Display that shows the status of the devices like ‘Device 1 turned on’.
It is pretty simple You should have only the basic knowledge about electronics and microcontrollers. To make this Home automation using Arduino and Bluetooth Now you can make this project by the given step at our website. Open the application and connect to the Bluetooth module. Bluetooth module receives them and the Arduino performs the operation, displays the status on the LCD, and sends a message back to the mobile.
Also, we need to download and install the Bluetooth Controller App on our Smartphone, Which is sending data to the HC-05 Bluetooth Module. This gives an ease of controlling the device just by giving speech commands. In the app, there are many buttons that send some variable when we press those specific buttons. Then the Arduino starts to compare the received data with the Database and generates the output signals accordingly.
These Lode Values are used in Arduino code to control a particular device by a particular app button. The Load values of the App buttons and their use is described in the below list. This is a 6 pin module, but in this project, we will use only 4 pins, these are VCC, GND, TX, and RX. The communication between the cell phone and the Arduino BT board is wireless.
