The Raspberry Pi was created with the goal of education in mind. This ultra-tiny computer was designed to be small and cheap so that schools could easily afford to teach students about computers in the classroom. This is great for two reasons, the first is that it provides extremely cheap access to a computer, and second it is a great tool for learning more about computers.
The Raspberry Pi is a low cost, credit-card sized computer that plugs into a computer monitor or TV, and uses a standard keyboard and mouse. It is a capable little device that enables people of all ages to explore computing and to learn how to program in languages like Scratch and Python. It’s capable of doing everything you’d expect a desktop computer to do, from browsing the internet and playing high-definition video, to making spreadsheets, word-processing, and playing games.
What’s more, the Raspberry Pi has the ability to interact with the outside world and has been used in a wide array of digital maker projects, from music machines and parent detectors to weather stations and tweeting birdhouses with infra-red cameras.
Raspberry Pi is the name of a series of single-board computers made by the Raspberry Pi Foundation, a UK charity that aims to educate people in computing and create easier access to computing education.
The Raspberry Pi launched in 2012, and there have been several iterations and variations released since then. The original Pi had a single-core 700MHz CPU and just 256MB RAM, and the latest model has a quad-core 1.4GHz CPU with 1GB RAM. The main price point for Raspberry Pi has always been $35 and all models have been $35 or less, including the Pi Zero, which costs just $5.
All over the world, people use Raspberry Pis to learn programming skills, build hardware projects, do home automation, and even use them in industrial applications.
The Raspberry Pi is a very cheap computer that runs Linux, but it also provides a set of GPIO (general purpose input/output) pins that allow you to control electronic components for physical computing and explore the Internet of Things (IoT).
The Raspberry Pi Foundation works to put the power of computing and digital making into the hands of people all over the world. It does this by providing low-cost, high-performance computers that people use to learn, solve problems, and have fun. It provides outreach and education to help more people access computing and digital making—it develops free resources to help people learn about computing and making things with computers and also trains educators who can guide other people to learn.
Some people buy a Raspberry Pi to learn to code, and people who can already code use the Pi to learn to code electronics for physical projects. The Raspberry Pi can open opportunities for you to create your own home automation projects, which is popular among people in the open-source community because it puts you in control, rather than using a proprietary closed system.
Raspberry Pi comes with 26 GPIO Pins are very useful indeed for embedded projects and interfacing hardware. These pins are really useful in learning about component interfacing. You can combine multiple digital sensors all together due to the good number of GPIO pins being given. It supports almost all the peripherals supported by Arduino.
It has a lot of accessories available for it in the market. You will find many Raspberry Pi cases with different designs, Raspberry pi HATs, Fans, Heat Sinks, etc… You will find a whole big community and support as well. It is said to be the most popular single-board computer of this era.
Raspberry Pi supports all types of codes. Its one of the best part of this board, if we compare it with Arduino you will know that Arduino only supports C, C++. While this board works as a single board computer. You get a Linux desktop environment in which you can code in almost any language, be it C, C++, C#, Ruby, Java, Python, etc.
This Support for all types of code makes this board famous, one of the main goals of the raspberry pi foundation was to provide cheap computing to people, so that they can learn programming. They have really reached their goal of providing cheap computing to people, so they can learn programming easily.
Moving towards the future, everything is turning digital, so we need more and more programmers. Raspberry Pi is really helping people who cannot spend much on desktop computers.
When we compare it with Arduino and other boards, you get a faster processor. Arduino comes with a controller, while here Raspberry Pi comes with a 1.6 GHz Processor in the 4B variant of Raspberry Pi. A faster processor means good performance. The price to performance of raspberry pi board is really great.
Since the raspberry pi doesn’t have any internal storage it requires a micro SD card to work as an internal storage. We all know that SD cards are not that fast. Even if we compare a class 10 High-Speed micro SD card with an eMMC internal storage. It lacks performance, so this increases the boot time of the board and read/write speed of the raspberry pi.
As the board doesn’t come with any heat-sinks pre-applied or any cooling fan. As the raspberry pi 4 comes with a powerful processor and multiple features, it starts to heat up after sometime due to the same board size, the heat dissipation is not proper as expected. If you use it for continuous 6-7 hours without air-conditioning or heat-sink.
When we look at the bigger picture of the board here and think of it as a desktop computer. It misses a lot of stuff. Even if you buy the latest raspberry pi with the 4GB ram. It lacks some performance. It is said to render 4K video at 60 FPS but in actual it is a bit less and you will see some stutters in 4K 60 FPS video.
If you open too many tabs, the board will start to slow down a bit. You can’t watch online videos on Netflix or Amazon, you will need to install extra codecs. even after that, you will barely be able to stream 2K properly. It needs some improvement and optimization in the software and hardware end both.
