If you’re at all familiar with do-it-yourself (DIY) electronics, you’ve probably heard about the comparable merits of Arduino and Raspberry Pi. You may have even, like I did, assumed they were competing hardware platforms solving similar problems.
Actually, Arduino and Raspberry Pi are quite different. For starters, Raspberry Pi is a fully functional computer, while Arduino is a microcontroller, which is just a single component of a computer.
Hardware And Software
Here’s an overview of some of the specs that show the biggest differences between the two:
The price and size of the two devices are comparable; we already knew Raspberry Pi and Arduino were tiny and cheap. It’s the stuff inside that sets them apart.
The Raspberry Pi is 40 times faster than an Arduino when it comes to clock speed. Even more seemingly damning for Arduino, Pi has 128,000 times more RAM. The Raspberry Pi is an independent computer that can run an actual operating system in Linux. It can multitask, support two USB ports, and connect wirelessly to the Internet. In short, it’s powerful enough to function as a personal computer (though not powerful enough to compete with your Mac or PC).
It might sound like Raspberry Pi is superior to Arduino, but that’s only when it comes to software applications. Arduino’s simplicity makes it a much better bet for pure hardware projects.
The Arduino IDE is significantly easier to use than Linux. For example, if you wanted to write a program to blink an LED with Raspberry Pi, you’d need to install an operating system and some code libraries—and that’s just to start. On Arduino, you can get an LED light to blink in just eight lines of code. Since Arduino isn’t designed to run an OS or a lot of software, you can just plug it in and get started.
Raspberry Pi can multitask processes—it can run multiple programs in the background while activated. For example, I have a Raspberry Pi that is serving as both a print server and a VPN server at the same time.
Raspberry Pi and Arduino are complementary.The Arduino is the sensory workhouse, while the Pi doles out directions.
They work great together,The Arduino is best for motor driving, sensor reading, LED driving, etc while you can have an Internet-connected Pi drive it, a mini computer that can play videos, music or send emails with ease.
