Arduino and RaspBerry Pi  What are they? + Differences ▷ 2021

Technology advances in different directions, from solving environmental problems to taking care of our health. But one of the paths that are clearer is to create smaller and more comfortable electronic components.

On the other hand, the development of free software grows in the same way as the interest of users to interfere in this world. These features gave rise to two of the most popular computing components among developers.

In this post we will show you the best features of Arduino and Raspberry Pi boards. At the same time, you will know if it is possible to use both electronic devices in the same project.

Arduino and Raspberry Pi What are these components and what are they for?

To better understand what each of these technologies is about, it is important know a little about its history and with it, its philosophy. Let’s start with Arduino. It began as an internal project of the Ivrea Interative Design Institute in 2005. However, given the unfailing closure of said institution, it was decided to release the project to the world.

From here begins one of the pillars of the Arduino project, that of being open in every sense, so that anyone can intervene in the evolution and improvement of software and hardware. As for Raspberry, share with Arduino the pedagogical origin of its purpose. Its beginnings date back to 2006, but it wasn’t until 2009 that the Raspberry Pi foundation was created. It would bring together academics and those interested in computing to create a microcomputer.

However, it was not until early 2012 that the first final version of the plate was released to the general public. In addition to its origins, We can say that both technologies have in common the objective of being the development base for computer science and robotics projects. The two boards can be used in conjunction with a wide variety of external hardware for different purposes. In turn, there are many software libraries developed for both boards.

These two developments share a similar goal, that of stimulating the creation of systems based on free programming. Both offer an accessible hardware platform that is compatible with many components. But it is also important mention that they are not exactly the same.

Let’s look at some of the most important differences:

Hardware philosophy

Although they share the openness of their software so that it can be modified, improved and shared, the truth is that Raspberry Foundation is the sole manufacturer of the boards Raspberry. For its part, Arduino is also open for any user to make their own version for free.

Microcontroller v microprocessor

It is important to clarify that Arduino is a design thought for control different processes to through your connections analog and digital and its integrated microcontroller. On the other hand, Raspberry, was designed from the beginning as a miniature computer, so it has its own microprocessor, this gives it greater computing power, although less versatility.


Raspberry boards have an integrated Ethernet and WiFi ports. That is, unlike Arduino, this plate does not require any external component to achieve these functions. Keep in mind that, being small plates, each port counts.


Here we find two important aspects that differentiate both plates. On one side, Arduino, once connected executes immediately the task for which it was scheduled. That is, for example, if it contains a code that makes an LED light blink, it will do so as soon as we start the hardware. In the case of Raspberry, first it is necessary to start the native operating system, and then give the order of execution. This makes any task that we indicate to the board a little slower.

This difference brings us to the second aspect, the complexity of the functions. Given the respective powers, Arduino is indicated for more basic electronic projects that do not require a lot of processing power. In this line Raspberry has an advantage, since it is a computer with its own operating system, capable of performing more complicated tasks.

Can Arduino and Raspberry Pi be used in the same development project?

Despite the differences between Arduino and Raspberry Pi they are a great complement to each other. Although it is advisable to start with a device that is easier to program such as Arduino boards, Dabbling in Raspberry won’t stop you from loving the microcontroller. On the contrary, you will find for yourself dozens of ways to use them together.

Such is the compatibility of both boards, that there is a project called Arduberry. It combines both platforms to take full advantage of the power of Raspberry in combination with the extensive offer of shields and accessories based on Arduino that exist today. Among some devices created by users, we can find the NFC card reader that combines an Adafruit NFC shield.

Which can be used as an access security key or perhaps as a work schedule controller. In turn, many users have started to use the capabilities of both boards at the same time. That is, connecting them to each other to achieve a specific goal. Usually a Raspberry Pi board with the function of a small laptop is used to control the code of Arduino IDE. In this way, it is not necessary to have a desktop PC, keeping the portable essence of the devices.

For example, it can be used to take a home garden to the next level. As we show in one of the examples in this post by Arduino-Raspberry Pi projects We can use Arduino to control the light and humidity sensors of our grow. But also combining Raspberry it is possible to make adjustments, inspect and execute commands remotely via the web. At the same time as generating automatic detailed reports.

In conclusion, not only is it possible combine the best aspects of both boards and languages, but it is one of the best steps you can take on your journey learning about electronics, programming and robotics.
