Arduino vs Raspberry Pi

Basics of Arduino and Raspberry pi

Basics of Arduino

Arduino is an open-source electronics platform. To make its use easy, Arduino consists of very simple software and hardware. Arduino boards can convert inputs like light from a sensor or a finger on a button into outputs like turning on an LED or starting a motor. You may tell the board’s microcontroller what to do by giving it a set of instructions. This is accomplished using the Arduino programming language (based on Wiring) and the Arduino Software (IDE) (based on Processing).

Arduino boards are microcontrollers, not full-fledged computers with their own operating system like the Raspberry Pi. They just execute C/C++ programs stored in their firmware. The Arduino Integrated Development Environment (IDE) is free software that allows you to program an Arduino board and upload your code to it.

Basics of Raspberry pi

A miniature computer that may be connected to a computer monitor, keyboard, and mouse. It has a dedicated processor, memory, and a graphics driver, just like a PC. It also comes with its own operating system, Raspberry Pi OS, which is a modified version of Linux.

Although the Raspberry Pi lacks storage, you can use microSD cards to store whichever operating system you choose (Raspberry Pi, Ubuntu Mate, etc.). Because the Raspberry Pi has Bluetooth, ethernet, and Wi-Fi connectivity, it may be used to transfer files over the internet. The software and the design of the Raspberry Pi project are not open-source.

Parts of Raspberry Pi

GPIO (General Purpose Input/Output) pins

DSI Display Port.

CSI Camera Port.

14 Differences between Arduino and Raspberry pi

Arduino Vs Raspberry pi

S.No: Arduino Raspberry Pi
1 It is a microcontroller It is a minicomputer
2 Can run only one program at a time Can run multiple programs at a time
3 Arduino has a very simple configuration to interface sensors and other electronic components. It Much more complex than Arduino like installing software and libraries for sensor interfacing and other components
4 Cheaper compared to Raspberry Pi Costly compared to Arduino
5 Can power the device by using battery pack Difficult to power the Raspberry Pi using battery pack
6 Need an external device to make a connection with the internet Can connect to internet by using Ethernet port and USB Wi-Fi dongles
7 It has onboard storage facility No onboard storage facility
8 Only one port to make connection with the computer It has four ports to connect various devices
9 It is a plug and play device Needs to shutdown properly otherwise it may corrupt files and software
10 C, C++, Arduino uses in Arduino Python is the recommended programming language, but C, C++, Python, and Ruby are all pre-installed.
11 The Arduino’s Control Unit is from the ATmega family. The Raspberry Pi’s control unit is from the ARM family
12 It has an 8-bit architecture It has 64-bit architecture
13 Arduino clocks 16 MHz (Megahertz) of processing speed in a system The Raspberry Pi clocks 1.4 GHz (Gigahertz) of processing speed in a system.
14 The logic level of Arduino is 5V The logic level of Raspberry pi is 3V
