Smart homes are now becoming a modern need and we are rapidly advancing towards it. Many people have started replacing their daily life objects with smart ones.

To turn ordinary things into advanced smart level objects, we require to embed smart chips or microprocessors in them. The most important factor in home automation is the use of microprocessors or single-board computers in smart home projects.

When it comes to the use of microprocessors in modern smart homes, there is a vast variety of single board smart computers available that can be used in smart home projects and devices.

Out of which following two are the best popular and best suited single board tiny computers that you can use in home automation and smart home projects.

  • Arduino
  • Raspberry Pi

You might be thinking that what is a single board computer?

A single-board computer is a complete computer built on a single circuit board. It is a motherboard composed of microprocessors, memory, input/output features, and other characteristics required for the functioning of a computer.

People are always interested in comparing things to choose the best one. For example, a comparison between Windows and Mac, AMD and Intel processors, and Raspberry Pi and Arduino Uno.

In this article a comparison between Arduino and Raspberry Pi is provided. Because they both are used to control electronic components, both are almost of the same size, and are pretty much popular.

But actually, they are different from one another in several aspects. Let’s proceed with an overview of both of them.


Arduino is a microcontroller board. This board is composed of integrated circuits, RAM, ROM, and all the components which are necessary for the proper functioning of a computer.

Arduino is manufactured by an Italian company Smart Projects. Arduino board uses a variety of microprocessors and controllers.

The primary objective of an Arduino board is to make ordinary objects smarter, as it provides the data processing ability to the object connecting to it.

Arduino comes in different sizes and shapes. So don’t worry about the size of your project.

All of them are similar to each other as they are built for the same purpose. Following are three types of Arduinos

  • Arduino Nano (smallest)
  • Arduino Uno (simple/general)
  • Arduino Mega (largest)

It was a quick intro about Arduino, if you want to study it in detail, you can find further details here.

Now let’s have a look at Raspberry Pi.

Raspberry Pi

Raspberry Pi is also a tiny single-board computer like Arduino.

Raspberry Pi was developed by Raspberry Pi Foundation collaborating with Broadcom back in 2012. Its primary objective was to promote teaching basic computer science knowledge wherever needed.

Its basic purpose is to control electronic components to explore Internet of Things (IoT). Even it can also be used for physical computing.

Raspberry Pi is used all over the world for different purposes. Such as to build hardware projects, for home automation, in industrial applications, and even to learn advanced programming skills.


Now let’s compare these two (Arduino Uno and Raspberry Pi) with each other. The objective is to highlight their qualities and characteristics in front of you.

Raspberry Pi (Left) and Arduino (Right)

So that you can decide which one is better to use and which suits your demands.

Explanation of Arduino

Arduino is a device that is used to control electronic components. You can add motors, lights, sensors, and wireless and Bluetooth modules. This makes Arduino a perfect platform for the manufacturing of robots.

The core of Arduino is the microcontroller. It is a smart chip developed by “Texas Instruments”. These microcontrollers are used to store, run and execute programs right within the chip itself.

More ever they even do not require much energy to run. A 9V battery is good enough for the proper functioning of Arduino.

It also has the option of attaching premade shields that are set at the top of the Arduino board.

Although these microcontrollers are mostly self-contained, efficient and smart but you still have to connect it to your computer to program it. As soon as you have uploaded your code into it then you can disconnect it and use it as a separate device.

All right let’s have a glance at Raspberry Pi now.

Explanation of Raspberry Pi

Raspberry Pi is composed of a microprocessor that requires some assistance from various chips to be able to store, run and execute code.

You would be definitely familiar with the motherboard of a Personal Computer. Like the motherboard, these boards contains a microprocessor with RAM, an Ethernet controller, a graphics controller, a hard drive, and all the other necessary components required for the computer to run.

So, when these components are shrink down to a single board, you will get you a Raspberry Pi.

GPIO Ports

GPIO (General Purpose Input Output) ports are little pins present in the board, that allows you to attach different devices with respberry Pi. The general-purpose input-output pins are used to control electronic component (such things as lights, motors, LCD, etc.) and are present both in Arduino and Respberry Pi.

GPIO is a great tool to learn Internet of Things and micro-circuitry. To program these pins, you can use different available popular languages but python is the best and the most suited to do so.

Which one should YOU buy?

As they are two different tools it depends on your demands or project that which one should be used.

You will never buy a PC to just see the calendar or you will not buy a calculator for surfing on the internet.

For Example, if you want to make a Bluetooth-controlled car. Your optimum choice would be an Arduino. But if you want to add a Webcam in the Bluetooth car for live streaming or else, then you might use Raspberry Pi.

Hopefully, this example cleared all your confusion regarding the choice “which one to use?”.

As a beginner which one should YOU use?

Arduino is designed especially for beginners. Its GUI makes it easier and simple for beginners to use it easily. Once you get used to Arduino then you can shift to Raspberry Pi.

That brings us to the end of the blog hopefully it would be beneficial for you.
