Advantages of Home Automation Using Arduino

Now you can build your own home automation project at a price you can afford. With the right mindset and a little bit of tech skills, you can build projects from the comfort of your home. Smart home devices are quite pricey. Also, they may or may not be designed for your home. Every home is unique, and you need custom-made smart devices— tailor-made just for you and your family. This post is about the advantages of home automation using Arduino. 

Advantages of home automation using Arduino

1. You don’t need to be an expert

To build home automation projects using Arduino you don’t need in-depth knowledge of electronics or programming. You don’t even have to be familiar with the theory they teach in tech schools. This is one of the biggest advantages of home automation using Arduino. 

I suggest you purchase a how-to book. Several books can teach you to build your own projects at home. You can get the required component online or in an electronics market nearby. For the most part, you will be interfacing sensors and actuators with Arduino. 

2. You get to build a system from scratch 

Creating something from scratch can be immensely satisfying for some folks. You can build a prototype using a computer simulator, and then create a prototype on a breadboard. You have the freedom to pick the component of your choice. The prototype can be used for testing out your favorite DIY home automation project. So, what are you waiting for?

3. Testing is amazingly simple

You can run your first Arduino program within minutes. By connecting the Arduino Uno board to the computer, you can run a simple LED blinker program to test whether everything is working fine. The Arduino Uno board is the interface between the Arduino chipset and the computer. You can load the blink sketch from your computer onto the chipset. 

Once the code burning process is finished, you simply have to put it onto a breadboard, connect the LED, and connect the controller to a battery. The LED will go on and off continuously. You can test your home automation projects in the same way. The schematics will help you prevent connection errors. You can always connect the microcontroller back to the computer and re-burn it with new corrected code.  

4. Build PCB with free-of-cost software

PCB design is an important part of building home automation projects with Arduino. Needless to mention, you must design the circuit virtually first, and then physically. You can accomplish this task with free PCB design software such as Eagle. You can download it from the Autodesk website. There’s a paid version available, but that’s for production. You don’t need to pay for training purposes or home use.  

5. Create 3D prints of your design 

Gone are days when getting approval for your product from a manufacturer was the most challenging part of project work. With open-source software like OpenSCAD, you can create a three-dimensional digital model of your proposed home automation product.

I agree with the fact that creating 3D models on OpenSCAD is not as straightforward, especially for someone with little or no knowledge of designing. But with perseverance, you will be able to create stunning models that will put the manufacturers in awe. 

How much does 3D printing cost? 3D printing is cheaper than traditional methods of building physical objects, but it depends on factors such as complexity of the model, material, and obviously the labor charge. You will be surprised to learn that some businesses might charge you as little as $5 an hour. 


There are more than one ways to build home automation projects using Arduino. You modify existing smart home products too— several of them are made using the Arduino system. Knowing the advantages of home automation using Arduino will motivate you to build projects on your own. That too, at the fraction of the cost of ready-to-use smart home devices.
