Home Automation system using Arduino and MATLAB

Published on 19 Jun 2021. Written by Amitesh Kumar

We all know how automation is taking over and the need for human interaction is minimal. This mini project is used to control the appliances of the house with the help of Arduino and MATLAB. Home automation is no new concept; around the world, it is a growing field of electronics which obviously require some computer concepts. MATLAB is an environment which is considered to be a numerical computing environment.

This language provides you with many functions such as matric manipulation, plotting of functions, data implementation, algorithms concepts, user interfaces, etc. Arduino is considered to be a very paradigm which is meant to communicate with the hardware with the help of software. MATLAB is a propriety programming language which is good for implementation of such kind of projects.

Project Implementation

For the project we will require the following parts: -

• Arduino UNO
• USB cable
• ULN2003
• Relay 5 volt
• Bulb with holder
• Connecting wires
• Laptop
• Power supply
• PVT

To get the communication between Arduino and MATLAB started we will need Simulink support or known as Arduino IO package. Basically, we will be creating push buttons to control the appliances of the home. We can create the buttons using GUI interface which will be saved with an extension of .fig. For the code and the GUI, it can be downloaded easily from the internet for free.

The design of the project is very easy as we have connected the circuit with the help of relay drivers. The ULN2003 will be used as the controller and the signals will be transmitted to the appliances. MATLAB programming code is used for the project. The coding of MATLAB is easy and you can learn from any online course. The whole code for the project can be easily downloaded.

The connecting wires from the controller to the appliances such as light, fan, etc. are supposed to be long as you will need to connect it with the laptop. As you will go in the application made by you, you can easily control the appliances. The call functions are created as an object in the code. The Arduino board will be used to transmit the signals easily to the controller. The Arduino board is also a very important part of the project.

The link which is the IO Arduino package is the link between the MATLAB and Arduino. You will be required to download this package and then signup for this. Upload the file to the Arduino using Arduino IDE. Visit MATLAB and then install the Arduino file from there to link these two environments.

Conclusion

The buttons will be an event which when fired will trigger the required action. The project is very simple and easily implemented. One should have some knowledge about MATLAB and Arduino for this project. Although downloading the code will help, but it is better to learn the essentials about both of this environment before you start with the project.
