What are the differences between the Raspberry Pi and the Arduino?

Raspberry Pi and Arduino are two famous electronics DIY builders, hobbyists, and even professionals’ boards. The Raspberry Pi and the Arduino are two distinct boards. Although Arduino is designed for fast programming and circuit prototyping, the Raspberry Pi is designed to teach computer programming. Each board has its own set of benefits and drawbacks.

Let’s take a closer look at these two boards to see what the gaps are between them. If you must choose between the two, your decision will be based on the needs of your project. However, we hope that this article has helped you appreciate the differences between the two boards and will assist you in choosing the correct board for your next project.

Raspberry Pi vs Arduino: What’s the Difference?

For teachers, beginners, and hobbyists, both Arduino and Raspberry Pi are excellent teaching tools. Let’s look at some of the distinctions between the Raspberry Pi and the Arduino.

  • The following is the key distinction between them: The Raspberry Pi is a microprocessor-based mini-computer, while Arduino is a microcontroller board (SBC).
  • The CPU, RAM, and ROM are all found on the Arduino board’s Microcontroller. All of the extra hardware on the Arduino Board is used for control, programming, and IO connectivity. With a processor, memory, storage, graphics driver, and connectors on the board, the Raspberry Pi SBC has many of the features of a device.
  • Raspberry Pi needs an operating system to work. No operating system is needed for Arduino. What you need is a compiled source code binary.
  • Raspberry Pi OS is a completely functioning operating system that comes with the computer (previously known as Raspbian OS). While the Raspberry Pi will run on various operating systems, the Raspberry Pi Foundation prefers Linux. If you like, you can install Android. There is no operating system on Arduino. All you need is firmware that tells the Microcontroller what to do.
  • The Arduino clock speed is 16 MHz, while the Raspberry Pi clock speed is about 1.2 GHz.
  • Raspberry Pi is ideal for writing Python-based software, while Arduino is ideal for interfacing sensors and controlling LEDs and motors.
  • This isn’t to say that we can’t use Raspberry Pi to link sensors and LEDs. The Raspberry Pi has a 40-pin GPIO, which can connect various electronic components such as LEDs, Buttons, Sensors, Motors and promote learning programming by controlling hardware. You may add a dedicated feature or functionality to Arduino using Arduino Shields, which plug into the Arduino Pin headers. Examples include a Motor Driver, Ethernet Connection, SD Card Reader, Wi-Fi, Touchscreens, cameras, and so on. Although the Raspberry Pi is a self-contained board, you may connect external hardware to it, such as a touchscreen, GPS, or RGB panels. The Raspberry Pi HAT Expansion Boards, also known as HAT Expansion Boards, are based on Arduino Shields, which can be used to extend the functionality of the Raspberry Pi. The GPIO Pins are attached to them.
  • Raspberry Pi and Arduino have entirely different power specifications. Even though they are both operated by USB (the Raspberry Pi via micro-USB or USB Type C and the Arduino via USB Type B), the Raspberry Pi needs more current than the Arduino. So, although Raspberry Pi needs a power adapter, Arduino can be powered directly from a computer’s USB port.
  • The Raspberry Pi’s hardware, software, and applications can be damaged if the power is interrupted. In the case of Arduino, a power outage causes it to restart. As a result, before disconnecting fuel, the Raspberry Pi must be properly shut down.
  • The Arduino IDE is used to write the code. While the Raspberry Pi may use Python IDLE, Eclipse IDE, or any other Linux-compatible IDE. You can also program directly in the terminal using a text editor such as Vim.
  • You can create your own Arduino board using Arduino’s open-source hardware and software files. Since the Raspberry Pi is not open-source, this is not feasible.
  • While the original Arduino UNO costs $23, many Arduino clones are available for less than $4. When it comes to Raspberry Pi, the original SBC cost about $35, but the new Raspberry Pi 4 Model B comes in three separate price ranges ($35, $55, and $75) depending on memory configuration.

How to decide between Raspberry Pi and Arduino?

To choose between the two, you must first determine what you want to accomplish with your project.

  • We can see from the above discussion that Arduino is ideal for routine tasks like opening the garage door, turning on and off the lights, reading temperature sensors, controlling a motor as the user desires, and so on.
  • Although Pi is capable of multitasking, such as controlling complex robots, playing videos, connecting to the internet, and interacting with cameras, it cannot perform multiple tasks.
  • For example, if you want to create an application that monitors humidity and temperature from a DHT11 sensor and displays the results on an LCD, you can use Arduino.
  • However, if you want to track Humidity and Temperature from a DHT11 Sensor, send an e-mail with the results, verify/compare the readings with an online weather report, and show the results on an LCD, Raspberry Pi is the right option.
  • In simple terms, Arduino is used for beginner projects and fast electronics prototyping, while Raspberry Pi is used for more complex projects.
