For comparing Raspberry Pi & Arduino, I intend to break down the explanation into three distinct sections:
- Arduino is a microcontroller motherboard. A microcontroller is a simple computer that can run one program at a time, over and over again. It is very easy to use. The Arduino only provides a subset of the functionality of the Raspberry Pi.
- Raspberry Pi is a general-purpose computer, usually with a Linux operating system, and the ability to run multiple programs. It is more complicated to use than an Arduino.
- HARDWARE & SOFTWARE
- The Arduino runs the Arduino firmware – a basic bit of core software that allows it to communicate with a computer over USB and gives access to all the features. You generally wouldn’t replace this firmware, but it is possible. Once your code has been loaded, you can just plug it in anywhere and it’ll start working immediately – you don’t need to reboot, plug in a keyboard, or choose an application to run. It does the one job it’s been programmed to do, does it well, and it does it immediately. The Arduino can be programmed with small applications written in C++, it cannot run a full-scale “operating system” and certainly won’t be replacing your media center anytime soon.
- The Raspberry Pi on the other hand is a fully functional mini-computer. It requires an operating system and takes a small amount of time to boot up before it is operational. Storage is provided from a micro-SD card, while built-in Ethernet allows for networking (you can get networking on Arduino too, but it requires an add-on “shield”). Raspberry Pi has a Broadcom Arm-v6 CPU; it has memory, and a graphics processor driving the HDMI output. You can plug in a keyboard and monitor, and load up Linux. The Pi is an incredibly powerful platform in a very small package — perfect for embedded systems, or projects requiring more interactivity and processing power.
- An Arduino board is best used for simple repetitive tasks: opening and closing a garage door, reading the outside temperature and reporting it to Twitter, and driving a simple robot.
- Raspberry Pi is best used when you need a full-fledged computer: driving a more complicated robot, performing multiple tasks, doing intense calculations.
- Both of them are equally important as both have different uses. So, it’s better to know both.But there is a problem for using Raspberry Pi, and it is that you will not get a lot of tutorials on it compared to Arduino. So, it’s better that you start with Arduino, make your concepts strong and then move towards Raspberry Pi.
