Introduction

Arduino and Raspberry Pi were significant players in the development of IoT devices. Both platforms can connect to the internet and communicate with other devices, making them ideal for IoT projects.

Difference Between Arduino and Raspberry Pi

Let’s see the difference between Arduino and Raspberry Pi!

What is Arduino?

Arduino is a microcontroller board designed for electronics projects. It was invented in 2005 by Massimo Banzi, an Italian engineer. It was designed to provide an affordable and easy-to-use platform for hobbyists, makers, and professionals to create interactive projects.

Arduino boards contain a microcontroller, digital and analog input/output pins, and a programming environment. The microcontroller is pre-programmed with a bootloader that allows it to be programmed using a computer via a USB cable. The programming language used is a simplified version of C++ that is easy to learn and use.

Arduino UNO

Key Features

  • Arduino boards typically run at 16 MHz, although some boards have a faster clock speed.
     
  • The microcontroller used in Arduino boards is usually an Atmel AVR or SAM3X8E ARM Cortex-M3 microcontroller.
     
  • Arduino boards operate at various voltages, depending on the specific board. Some boards operate at 5 volts, while others work at 3.3 volts.
     
  • Arduino boards come with limited memory for storing programs and data.
     
  • Arduino boards can be extended with additional hardware modules called shields. These shields can add functionality to the board, such as Ethernet connectivity, wireless communication, or motor control.

What is Raspberry Pi?

Raspberry Pi is a single-board computer (SBC) powered by the Linux operating system. Unlike microcontrollers, Raspberry Pi has a full-fledged operating system, a powerful system-on-chip (SoC), and a GPU, making it more suitable for applications that require complex processing and multimedia capabilities. 

Raspberry Pi can be programmed using various programming languages such as C,  Python, and Java and can be used for a variety of applications, including home automation, robotics, and multimedia. Raspberry Pi can run Linux-based operating systems such as Raspbian, a version of Debian optimized for the Pi.

Raspberry Pi 3

Key Features

  • Raspberry Pi uses a Broadcom system-on-a-chip (SoC) with a 64-bit quad-core ARM Cortex-A72 CPU, providing excellent processing power for various applications.
     
  • It has a microSD card slot for storing the operating system and data. It can also be connected to external hard drives or other storage devices for additional capacity.
     
  • It has a set of general-purpose input/output (GPIO) pins, which can be used to interface with external sensors, actuators, and other electronic components. 
     
  • It comes with varying amounts of RAM, ranging from 1GB to 8GB, depending on the specific model.
     
  • It has built-in WiFi and Bluetooth connectivity, allowing it to connect to other devices and networks without additional hardware.
