Isn’t it really interesting to see the world shrinking day by day? Of course, it is. At least to me, things turning from mini to micro is the call of next generation. From ages unknown, technology has kept unveiling enthralling devices and platforms that have always made life easier. Computers are one such innovation, non-existence of might have turned the world meaningless. When we talk about computers, it would not be fair if I do not mention single board computers. Yes! I am speaking about Raspberry Pi.
Basic Difference between Raspberry Pi and Arduino
A Raspberry Pi is basically a single board general-purpose computer that was developed for teaching purpose in schools. It usually has Linux operating system. And, voila! It can run multiple programs and support two USB ports simultaneously. A Pi computer can even connect to the Internet wirelessly. Arduino, too, needs mention here because it is also a simple computer developed for teaching purposes. However, Arduino is a simplified microcontroller that can run single programs.
You can use a Raspberry Pi for developing retro game consoles, home automation systems and robotics. While, an Arduino micro-controller can be used to control various simple and repetitive tasks such as closing a garage door, driving robots, working of a Maker Bot- 3D printer, etc. The speed of a Raspberry Pi computer is approximately 40 times greater than that of Arduino. In addition, Raspberry Pi has 128,000 times higher RAM than Arduino.
Are you getting the idea that a Raspberry Pi is superior to Arduino? However, it is true only in terms of software applications. The simplicity of a Arduino micro-controller makes it a preferred option for various hardware projects. Arduino is capable of performing ‘real-time’ and ‘analog’ operations unlike Pi. This makes it a better choice for developing sensors or chips. Comparatively, Raspberry Pi is not as flexible as Arduino.
Uses of both the single board processors
The Arduino IDE is significantly easier to use. For instance, if you wanted to write a code for a blinking LED using Raspberry Pi, it will be essential to install an operating system and get into coding to begin with. But, it’s a matter of just a few lines of a simple code on Arduino to get LED blinking. To get an Arduino working you just need to plug it in and get started.
Multi-tasking of a Raspberry Pi enables functioning as a print server and a VPN server, both at the same time. In contrast, you can leave an Arduino continue performing a single task for a long time. You can simply unplug when you do not require it further or want to stop the process.
When it comes to choosing between Arduino and Raspberry Pi, the task is a bit tedious. You need to do a bit of brainstorming with a few questions such as:
- Purpose or task you want to accomplish.
- Benefits of using a particular single board computer.
- What can be the drawbacks associated with it?
You may consider these features to make your decision:
Basic Purpose: Arduino, a microcontroller, performs best in governing small machines such as sensors, motors, LEDs and related purposes that involve the use of these devices. On the other hand, Raspberry Pi, a single board computer, performs various complicated tasks just like a computer. The device is acts as an excellent server too.
Power Supply: To get the Arduino running, you simply need to plug it into your computer or a battery pack. And, there you go. It starts start running immediately, and stops when gets disconnected. While, the Raspberry Pi must be shut down just like a computer, and abrupt power cuts can damage it. However, both the devices consumes minimal power.
Connectivity: There is a built in Ethernet port in Raspberry Pi and can be instantly connected to the internet. You can also get a USB WiFi dongle for wireless connectivity. This is why the Pi is usually chosen for personal web servers, printer servers, and VPNs. The Arduino has no such capability. If you want to connect the device to the Internet, you must add an extra piece of hardware with an Ethernet port. For WiFi connectivity, you’ll again require an additional hardware.
Storage: Arduino has a 32 KB of onboard storage to store the code that gives instructions for its current program. You cannot use this for storing apps, videos, etc. There is no onboard storage in Raspberry Pi. It rather has a micro SD port in which you can add as much memory as you want.
USB: The Arduino doesn’t come with any standard USB port for communication with computers. You can use a single port to connect it to your computer using the computer’s USB port. There are four USB ports in Raspberry Pi. You can utilize them to connect the device to a router, printer, or any external hard drive.
