Arduino and Raspberry Pi--all roads leads to Rome

Arduino and Raspberry Pi (now some of them have a Raspberry Pi touchscreen accessory in the works) are both fit for beginners when they were used as teaching tools. However, when examined their hardware and software, you will find that they’re used for different types of projects.

Actually, Arduino and Raspberry Pi are different. For starters, Raspberry Pi is a fully functional computer, while Arduino is a microcontroller, which is just a single component of a computer.

Raspberry Pi, which was created in the United Kingdom, was invented by Eben Upton and his colleagues at the University of Cambridge. It was designed to be a cheap computer for improving tinkering skills.
However, the Arduino, which was born in Italy, was named after the bar where the inventor named Massimo Banzi first come up with the idea.
There are no big differences between the Arduino and Raspberry Pi in price and size because they are all cheap and tiny (The biggest online store is sainsmart). Which make them different was the stuff inside.
The Raspberry Pi is an independent computer that can run an actual operating system in Linux. It can multitask, support two USB ports, connect wirelessly to the Internet and is 40 times faster than an Arduino when it comes to clock speed.
But it is not mean that Raspberry Pi is better than Arduino, when it comes to software applications. Arduino’s
simplicity was much better for pure hardware projects than Raspberry Pi. 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. While on Arduino, you can get an LED light to blink in just eight lines of code. Since Arduino isn’t designed for lots of software, you can just plug it in and get started.
In a word, the Raspberry Pi is better in software application while the Arduino makes hardware projects easier than Raspberry Pi. You can pick one of them depends on your need.
