Difference Between Arduino And Raspberry Pi (How To Decide The Board)

You must have heard about the Arduino and Raspberry Pi in your electrical and electronics degree, they both are quite famous among students and hobbyists. But have you ever wondered what are they, how they both are different from each other?

A Raspberry Pi is a mini-general-purpose computer that ordinarily comes up with a Linux-based operating framework, and it can multitask. It can be utilized for doing seriously calculative and scientific operations such as for Bitcoin or encryption technologies.

On the other hand, Arduino is an open-source computer program and hardware company. It is widely used among the undergrad students of electrical students because of their simplicity, and easy to use.

An Arduino is primarily a microcontroller motherboard which could be a basic computer dealing with only one program at a time, over and over. Arduino is a microcontroller whereas Raspberry Pi is a microprocessor. Indeed though Raspberry Pi is more capable, it requires an operating system, more control and is additionally more costly than an Arduino. Therefore, both have their own functionality. It depends on the project requirements.

Raspberry Pi and Arduino are two exceptionally popular boards among hardware DIY builders, specialists, and indeed experts. Raspberry Pi and Arduino are very distinctive boards. Whereas Arduino is pointed at speedy programming and circuit prototyping, Raspberry Pi acts as a learning device for Computer Programming.

Everything in the world has its pros and cons, so do both of them. Here are 7 reasons you should know before you go ahead and buy either board.

7 reasons about Arduino and Raspberry pi (The most important points)

Which board should I choose as a beginner (Arduino or Raspberry Pi)?

As I said over, Arduino finds its use in comparatively less complex projects where one has to perform a repetitive task like exchanging on an engine, moving a basic bot, perusing and detailing temperature, etc.

On the other hand, Raspberry Pi finds its use in complex applications where you’re feeling the need to use a computer. Consider utilizing Raspberry Pi in case you’re making a complicated robot, looking to memorize to hack, managing complicated calculations, requiring more preparation control, etc.

On the off chance that you’re getting started and are still incapable of choosing which one to purchase, go and get an Arduino, it’s made for beginners.

What languages do Arduino and Raspberry PI use?

How to decide which board is better (Arduino or Raspberry PI)?

The Arduino Uno and the Raspberry Pi 3 are well-known choices when it comes to DIY, IoT, or just fun building projects. They can be used for prototyping and real-world building arrangements (i-e. Into the Blue utilizing Arduino & Raspberry Pi boards for an underwater camera). In case you’re having trouble finding which one to utilize for your project, let’s see what each board offers.

Both boards look comparable, but they are each in their claim category. The Raspberry Pi 3 could be a Single Board Computer (SBC). This implies that the board may be a completely utilitarian computer with its claimed devoted processor, memory, and can run a working framework (runs on Linux). The Raspberry Pi 3 incorporates its claimed USB ports, audio output, and features a realistic driver for HDMI yield, appearing how it can run multiple programs.

You’ll indeed introduce other working frameworks that incorporate Android, Windows 10, or Firefox OS. The Arduino Uno Rev 3 may be a Microcontroller. Microcontrollers are not as effective as SBCs, but they can be extraordinary for fast setups. Microcontrollers exceed expectations when controlling little devices (like LEDs, engines, a few distinctive sorts of sensors) but cannot run a fully working framework. The Arduino Uno runs one program at a time.


In conclusion, on the off chance that you have got a project that includes a few functionalities at the same time, requires simply getting to the Web, and requires media accessibilities, the Raspberry Pi 3 will be your go-to board. If you’ve got a project that needs simple reads from sensors, as it needed to do a number of out based on the sensor information, communicates effectively with other machine parts, and need a fast start-up with nearly no other establishment, at that point the Arduino Uno in the event that the one for you.
