Arduino vs Raspberry Pi: Which Board Wins ?

Arduino vs Raspberry Pi

You could not have ever utilized Arduino vs Raspberry Pi. Still, odds are you have heard of these. Raspberry Pi has become the bestselling British computer for many years now, also Arduino has been changing the DIY community one plank at one time.

There is no lack of alternatives developed to provide you with digital remote control over your projects. Nonetheless, the budget-friendly Raspberry Pi, as well as the abundance of solutions below the Arduino manufacturer, are two of the hottest.

But comparing both could be similar to judging a lineup of dogs and cats. They are both critters that stink themselves. However, they dig holes for entirely different motives. Colorfy has spared you the trouble and pitted Arduino versus Raspberry Pi to help you determine what is ideal to buy for the next project.

What’s Raspberry Pi?

The Raspberry Pi was the first powerful single-board microcomputer under $50. Constructed for schooling, it was adopted by the DIY and the PC community equally. In general, there were over 14 million units sold before 2017.

Among the factors for its unbeatable cost is its complete PCB design. The Raspberry Pi provides all of the computer demands: A processor, memory, GPU, input signal, SD card slot, and presses on a charge card-sized plank.

Any Raspberry Pi it’s capable of running some programs or jobs. Additionally, you can opportunity different working systems by merely swapping the SD card, which holds the operating system. In 99 percent of those circumstances, a Raspberry Pi will probably operate on a Linux derivative as an operating system (such as Raspbian or Ubuntu); however, the tiny machine may run Windows 10 IoT Core.

Contrary to an Arduino, it comes with USB ports, an audio card, and integrated images because of the HDMI output.

What’s Arduino?

Arduino is a microcontroller. This usually means that an Arduino is a real computer that could run one program iteratively. Arduino boards may read inputs – i.e., pressing on a button, sensing mild, getting a Twitter message – and respond to it by anything they’re programmed to in their output – triggering an engine, turning in an LED, publishing something online.

Its ease of usage and the available hardware for different producers to make their boards are crucial advantages differentiating Arduino from a single-board computer (SBC) such as a Raspberry Pi.

Many Arduino boards are less successful as a single-board computer. Thus, Arduinos are often favored for tackling one job only. Consider it as the mind for your DIY programming projects. Furthermore, their fast setup is a fantastic benefit if only you have a particular position in mind.

All of Arduino boards are open-source, which permits users to accommodate the microcontroller for their needs completely. The excellent benefit is that it’s comparatively straightforward for beginners and flexible enough for more sophisticated users, that have significantly more complex tasks in your mind.

The Raspberry Pi includes many distinct versions, all powered by an ARM CPU. In the first single-center 700MHz version in 2012, the quad-core 1.5GHz version of today. The Arduino versions are generally powered by Atmel microcontrollers and are usually less than 100MHz. By way of instance, the Arduino Uno runs at 16MHz.

These processors are considerably slower than those located from the Raspberry Pi, but the Arduino doesn’t possess as many overheads as running a Linux operating system. When we conducted an evaluation based on pure “horsepower,” then the Raspberry Pi could win. However, there’s something to be said for a CPU using a predetermined rate. It’s reliable, and there’s no scaling that could lead to time issues for projects that need absolute precision.

For absolute CPU power, the Raspberry Pi has always been the obvious winner. Arduino’s Portent H7 is a useful board, but it can’t fit the Pi in electricity. The cheapest spec Raspberry Pi that we could purchase is your Raspberry Pi Zero W that has one 1GHz CPU and provides more raw energy than the double core 480MHz STM32H747. However, the Raspberry Pi requires larger power since it also runs a working system.

Power Requirements

If it comes to energy consumption, the Raspberry Pi is instead a starving board. There was a new USB C power connector along with the Raspberry Pi along with a high rated official electricity source device providing up to 3A to your Pi and any device attached to it. Therefore a Raspberry Pi 4 may theoretically operate at around 15W. An Arduino Uno can pull a maximum of 500mA through USB. It may draw more present if utilized.

Flexibility is your winning attribute. The Arduino Uno can operate with various voltages controlled to the 5V required for the board. Power may be supplied through the USB port, a DC socket jack (6 to 20V that is routed with a 5V regulator), or through the VIN pin that goes right to the microcontroller, so always ensure the proper voltage before connecting. The current draw for an Arduino Uno conducting the “blink” sketch is about 40mA but incorporating elements increase the quantity of current used.


The Raspberry Pi has a built-in Ethernet interface and Wireless N connectivity, which allow simple access to any system with minimal installation. As soon as you’re connected, you may use the operating system to link to internet servers, process HTML, or place to the net. You may also use it as a VPN or publish a host.

Regrettably, Arduino devices typically are not constructed for community connectivity straight from the box. Even though it’s potential, they need somewhat more tinkering to prepare a proper relationship. You will want an excess chip equipped using an Ethernet jack. You will want to do some programming and wiring to have everything ready to go just right, which will be sufficient for this process in itself, in which some sellers sell similar Arduino devices using a built-in Ethernet port.

Processor Speed

The difference in processor speed between Raspberry Pi and Arduino is very apparent and enormous. The former is still a fully operational computer, whereas the alternative is a microprocessor. Assessing the clock rate of Arduino Uno plank and Raspberry Pi Model B plank, we see the worth 16 MHz and 700 MHz, respectively. Hence, the Raspberry apparatus is 40 times faster than the Arduino board. The Pi board also includes a shocking 128,000 times more RAM than the Arduino board, consisting of a RAM of 0.002 MB.

One crucial consideration to keep in mind is that Arduino is only a plug and play device and may be switched ON and OFF at any time with no damage. However, the Raspberry Pi operates on a working platform and is a complete computer, which takes a proper shutdown until electricity is removed. Improper shutdown(s) of Raspberry Pi may hurt the plank, corrupt the software, and even alter the processor rate.

Available Programming Languages

The Raspberry Pi single-board pc was created to encourage kids to join the subject of programming. The Pi at Raspberry Pi comes in the Python language, which denotes its usage from the computer. Though Raspberry Pi has embraced numerous programming languages at a brief period, it’s existed, because of which it is now the first choice for a huge set of programmers. A Few of the languages offered to be used in Raspberry Pi is Scratch, Python, HTML 5, JavaScript, JQuery, Java, C, C++, Perl, and Erlang.

In the instance of all Arduino, you may meet Arduino IDE-a cross-platform UI used to compose and upload programs to the plank. It’s written in the programming language Java and assists anybody in starting Arduino programming quite readily. But in high-end projects, the Arduino IDE functions as a limitation on what could be accomplished. If you don’t want to utilize the IDE, you can code the Arduino with the C++ language.

There are some different tools out there for novices and professionals to utilize while programming at Arduino. One such instrument is ArduBlock, which aids novices with none to minimum programming expertise picture their code instead of form it, helping them understand the logic. Another visually established instrument is Snap4Arduino that concentrates less on programming but more about supporting the user know how it functions since it’s constructed for slightly older viewers. Additional languages that may be utilized directly or indirectly through outside communicators are C# and Python.


The Raspberry Pi is a fully functional Linux desktop computer and may be used for day to day tasks or as a host and provides the GPIO, which sees the computer being used in projects great and small. The Raspberry Pi packs a great deal of functionality into a credit card-sized plank from just flashing an LED to computer vision, machine learning, and robotics.

In reality, the Raspberry Pi may do everything an Arduino can perform. It will still require assistance in the kind of HATs and put in on boards because particular features like analog-to-digital conversion are not built-in.

It’s correct that a Raspberry Pi will lack the immediacy of an Arduino. Once all of the Raspberry Pi is a pc that needs to load the operating system before any work may be done, also, if you would like to turn it off, then you should issue a shutdown command and wait patiently for your machine to power off itself.

The Arduino is one task board that runs only one program at one time and instantly starts once you power it up and, even if you would like to turn it off, it’s possible to pull the plug. The immediacy of this Arduino is a big selling point for projects which catch information or accessible robotics.

The Arduino is a flexible board; however, the Raspberry Pi is a complete computer and a hardware hacking platform. Should you require wireless communication, raw processing capacity, and accessibility to the GPIO subsequently, the Raspberry Pi provides you all that in a little bundle.

Input/ Output (I/O) Pins

The I/O pins in your single-board computer enable it to speak to other devices attached to it. By way of instance, should you want to trigger a light or motor up an LED with your single board, you want those I/O hooks to execute these jobs. The Raspberry Pi (Model 2) includes 17 I/O hooks to provide, while the Arduino (Uno) plank packs 20 pins.

Another crucial issue to notice is that the temporal resolution in the board can restrain these hooks. Since the Raspberry Pi is a complete pc, its CPU may be hogged up by numerous different jobs, resulting in difficulty in receiving the control time to a minimum. In Arduino’s instance, the input signal can be tracked to some minimum worth of time to modify the output into the desirable degree.


While Raspberry Pi and Arduino apparatus have many interface ports, connecting analog sensors to the Arduino devices is a more straightforward process. The micro-controller can quickly interpret and react to a broad selection of detector information using the code you put onto it, which can be excellent if you would like to replicate a string of commands or respond to sensor data method of earning alterations to servos and apparatus.

On the other hand, Raspberry Pi planks need applications to interface with these kinds of apparatus, which is not necessarily what you desire if you are only trying to water plants efficiently or maintain your beer cold. Utilizing equally in a project is not all that rare. The Arduino device could function as a controller board that implements commands issued from the Raspberry Pie’s applications until the sensor data is fed back to get acknowledgment or recording.


Raspberry Pi 3 version B+ costs around $35. The cost to get Arduino Mega 2560 R3 Microcontroller rounds precisely the very same numbers. Nonetheless, many boards on either side (but exponentially bigger in Arduino are still available in the industry. Thus, cheaper boards may be favored, beginning under $10 for the two Arduino and Raspberry Pi. Therefore, if you don’t have to purchase by the dozen, then the two systems are cheap.


Raspberry Pi and Arduino display some notable differences, which can be both significant and subtle. Both boards have a considerably long list of pros and cons. However, they’ll fit perfectly in the event the requirement is proper. But regardless of how different they might appear, there is a situation where they may work together to help optimize their project’s outcome. You can compare the Arduino board to this human body’s spinal cord, making small-scale decisions like a light an LED or carrying a liquid’s temperature. In contrast, the Raspberry Pi plank is your mind, which requires complicated decisions, such as evaluating their previous values and forecasting the future worth.

In the long run, as we’ve discussed, the Arduino board is excellent for you if you’re a beginner and would like to learn about electronics or somebody who hails from a digital background and wants to take up easy projects. Raspberry Pi is ideal for you if you have Linux knowledge and need to build upon it by producing complex networking digital projects.
