What’s The Difference? Arduino vs Raspberry Pi

When it comes to single-board computers, two big names tend to dominate the conversation: Arduino vs Raspberry Pi. Both are incredibly popular choices for DIY projects and electronic tinkering, but which one is the right choice for your needs? but what’s the difference between the Arduino vs Raspberry Pi?

Arduino vs Raspberry Pi is a big difference. Arduino is a microcontroller, while Raspberry Pi is a mini-computer. They both have their pros and cons, but overall, they’re pretty different. Arduino is better for hardware projects while Raspberry Pi is better for software projects.

What is Arduino?

An Arduino is a microcontroller board that is based on the Atmel AVR microcontroller. It was created in 2005 to make it easy for people to create electronic projects.

Arduino vs Raspberry Pi

It is similar to a regular computer, but it has a special microcontroller that allows it to control things like motors and lights. You can use an Arduino to make your electronic projects, or you can use it to control other devices. Arduino is open-source, which means that anyone can use the board to create their projects. The Arduino software is also open-source, and it is easy to use, even for people who are not experienced with programming.

Arduino is popular for two main reasons. First, it’s inexpensive. Most Arduino boards cost less than 20$. Second, it’s easy to use. Arduino’s programming language is based on C++, making it relatively easy to learn. There are a variety of Arduino boards, each with its own set of features.

The most popular Arduino board is the Arduino Uno, which has 14 digital input/output pins (6 of which can be used as PWM outputs), 6analogueg inputs, and a USB connection. Arduino boards can be used to control a variety of devices, including LEDs, motors, and sensors. They can also be used to create interactive projects, such as games, musical instruments, and robots.

Arduino vs Raspberry Pi
Raspberry Pi

Raspberry Pi is a credit-card-sized computer developed by Rasberry Pi Foundation in 2012. It was designed to promote the teaching of computer science in schools. Raspberry Pi is also open-source, and it runs on the Linux operating system. What is Raspberry Pi And Their Uses – Beginner’s Guide

It is a capable little gadget that enables people of all ages to explore computing and to learn how to program in languages like Scratch and Python. It’s capable of doing everything you’d expect a desktop computer to do, from browsing the internet and playing high-definition video, to making spreadsheets, word-processing, and playing games.

The Raspberry Pi has a much more powerful processor than the Arduino, and it also has a GPU. This means that the Pi is capable of running much more complex programs than the Arduino.


  • Superior software implementation

There are a few key differences between the Arduino and Raspberry Pi. The biggest difference is that the Arduino is a microcontroller, while the Raspberry Pi is a full-fledged computer.

This means that the Arduino is much better suited for projects where you need to control specific hardware, like sensors or motors. The Raspberry Pi, on the other hand, is better suited for projects where you need a full-fledged Linux operating system and a wider range of software options.

Another key difference is that the Arduino is much simpler to use than the Raspberry Pi. The Arduino IDE is very user-friendly, and there is a wide range of libraries available for the Arduino that make it easy to interface with sensors and other hardware.

The Raspberry Pi, on the other hand, requires a much greater understanding of Linux and programming in general.

Cost Arduino boards are cheaper. Raspberry Pi boards are expensive.
How they handle power drop Arduino devices begin executing code when they are turned on. Therefore, when power is turned off, abruptly, you won’t end up with a corrupt operating system or errors. The code will simply start again when plugged in. Raspberry Pi requires the same care as a PC. You have to shut the operating system down properly.
Current drive strength Higher current drive strength Lower current drive strength
Capability Arduino is generally used to perform single (and simple) tasks repeatedly. Raspberry Pi can perform multiple tasks simultaneously.
Wireless connectivity Arduino does not support Bluetooth or WiFi. Raspberry Pi supports Bluetooth and WiFi.
Applications Traffic light countdown timer, Parking lot counter, Weighing machines, etc. Robot controller, Game servers, Stop motion cameras, etc.

Which One Is Better Arduino or Raspberry Pi

Arduino is much cheaper than the Raspberry Pi. The Arduino Uno, for example, can be purchased for around $30, while the Raspberry Pi is around $40. This makes the Arduino a great option for projects on a budget. So, which one should you use? It depends on what kind of project/s you are going to do. If you need a simple way to control hardware, the Arduino is probably your best bet.

Arduino is better for hardware projects while Raspberry Pi is better for software projects. it depends”.
