Difference between Arduino and Raspberry Pi

Today we are going to see the comparison between Arduino & Raspberry Pi. Before that, we have known the basics of Arduino and Raspberry Pi.

Arduino and Raspberry Pi are two popular hardware platforms used in electronics and programming projects. While they both serve similar purposes, they differ significantly in terms of hardware, programming, processing power, and other factors. In this article, we will explore the key differences between Arduino and Raspberry Pi to help you choose the right platform for your next project.

Arduino vs Raspberry pi

What is Arduino??

Arduino is an open-source development board that is used to build electronic gadgets, embedded designs, and wearable devices, robotics & IoT projects. Arduino is a platform where one can hobbyists, beginners, students, or programmers can develop projects, and devices by connecting multiple sensors, and motors. Arduino board consists of ATmega328P 8-bit microcontroller which has 0-13 digital pins, these pins are used for both digital input to read from the device & digital output to send data to the device from Arduino. Out 0f 13 digital pins Arduino has 6 ~ PWM pins used to vary the output voltage. Arduino has 6 analog pins to read analog values from the sensor. Arduino has a 5v operating voltage with a current consumption of 45-80 mA; in deep sleep, it consumes 35 mA. Arduino board has an operating frequency of 16 MHz which means 16 million instructions are carried out per second. Arduino can either be powered through the USB connection from the computer, from a 9V battery, or from a power supply. Arduino has a barrel jack to power on board and a USB port for code upload.

Arduino is an open-source electronics platform based on easy-to-use hardware and software. It's designed to make it simple for hobbyists, designers, and professionals to create interactive projects that can sense and control the physical world.


Arduino

Arduino has a flash memory of 32kb, SRAM of 2kb & EEPROM of 1kb. Flash memory and EEPROM memory are non-volatile (the data is still present even after the power is turned off). SRAM is volatile means information will be lost when the power is cycled. Arduino uses SPI, I2C communication & UART communication protocols to communicate Arduino with another device. Arduino boards are able to read inputs - a light on a sensor, a finger on a button, or a Twitter message - and turn it into an output - activating a motor, turning on an LED, or publishing something online. You can tell your board what to do by sending a set of instructions to the microcontroller on the board, this set of instructions is written in the Arduino programming language (which is based on Wiring), and the Arduino Software (IDE), based on Processing. 

Arduino is widely used in thousands of different projects and applications. The platform is a great tool for making interactive objects, taking inputs from a variety of switches or sensors, and controlling a variety of lights, motors, and other physical outputs. Arduino projects can be stand-alone, or they can communicate with software running on a computer (e.g., Flash, Processing, MaxMSP). Arduino boards can be built by hand or purchased pre-assembled.

 There are different types of Arduino boards available

  • Arduino Uno: This is the most common Arduino board, great for beginners and simple projects.
  • Arduino Mega: It's like the Uno, but with more pins and memory - great for bigger projects.
  • Arduino Leonardo: Similar to the Uno, but with a different microcontroller that allows for different functionalities.
  • Arduino Nano: A small, breadboard-friendly board.

What is Raspberry Pi??

Raspberry Pi is a series of low-cost, credit-card-sized single-board computers that can be used for a variety of purposes, such as learning to program, running basic computer applications, and building DIY projects. The Raspberry Pi was first introduced in 2012 by the Raspberry Pi Foundation, a UK-based charity that aims to promote computer science education and the use of technology for social good.

The Raspberry Pi is designed to be an affordable and accessible platform for learning and experimentation. It is equipped with a processor, memory, USB ports, HDMI port, and other components that are found in traditional computers. It can be used as a standalone computer, or as a component in a larger project, such as a home automation system, a media center, or a gaming console.

Raspberry pi

The Raspberry Pi runs on Linux-based operating systems, such as Raspbian, which is specifically designed for the Raspberry Pi. It can also run other operating systems like Ubuntu, Windows 10 IoT Core, and others.

One of the key features of the Raspberry Pi is its versatility. It can be used in a wide range of applications, from basic programming projects to complex industrial control systems. It has become a popular platform for makers, hobbyists, educators, and researchers.

The Raspberry Pi is also supported by a large and active community of developers, users, and enthusiasts. There are many online resources, tutorials, and forums dedicated to Raspberry Pi, making it easy for anyone to get started with this platform.

Overall, the Raspberry Pi is a powerful and flexible platform that offers an affordable and accessible way to learn programming, experiment with electronics, and build DIY projects. Its popularity has contributed to the growth of the maker movement and has inspired many people to explore the possibilities of technology.
