From a Coffee machine to a small academic project of building a rocket, Raspberry Pi (or the R Pi for short) can help in building them all. RPi is making its way to many basic as well as advanced research based applications as its a fully fledged computer that can fit into the palm of the hands. According to the Guardian Magazine February 2016, the Raspberry Foundation (makers of RPi) announced that they have sold 8 million units, making it the best selling UK personal computer. The fact by itself is indicative of the advantages and power that a small RPi has. With the recent release of Raspberry Pi 3, there is not only a lot of curiosity about the product in the minds of people but a lot of commotion too. Joining R Pi with the Arduino, opens up yet another possibilities for many engineering projects at low cost. Read More to know the basics, major features, project and setup of R Pi along with the challenges that are solved by Raspberry Pi 3 and its other generations.



What is the Raspberry Pi?

The correct term for the Raspberry Pi is a single-board computer (SBC) which is the size of a student's ID card. In simple words it is a mini and cheap version of the regular desktop and laptop computer, which one has seen in almost every home and office. While most laptops and machines like the Dell, HP, and other company ultra-books also come under the single board category, the difference between Raspberry Pi and other small computers is that, RPi is a low cost device that is worth around $35, making it a perfect gift for kids to start with programming and also for those who need a computer just for the purpose of Web surfing. The product was designed with the goal to teach young people how to program. It can do almost anything, which a regular computer can do including surfing the web, programing in languages like Python, Java, C etc. For engineering student who work with Arduino, the difference between an Arduino and the Raspberry Pi is that the Arduino is a micro controller while the R Pi is a single board computer. Another major fact is that the Raspberry Pi board runs an operating system and programs on the operating system while the Arduino is a controller board. The code must be downloaded, directly to the controller board and Arduino will run that program only.

Difference between Raspberry Pi 2 and Raspberry Pi 3?

Raspberry Pi 3 is the first 64 bit computer from the Raspberry Pi foundation. 64 bit mean more power, but it does not have any lack in compatibility. All the existing programs and projects of Raspberry Pi 2 will work just fine on the RPi 3 as well. It has a BCM 2837 CPU which contains a 1.2 GHz, 64-bit quad core ARM processor. It also has a VideoCore IV GPU which is the same as in its predecessor Raspberry Pi 2. Other differences include the addition of the Wifi and Bluetooth capability and of course the 64 bit, 1.2 GHz processor which is faster as compared to the 32 bit, 900 MHz processor of the RPi 2.

What is use of Raspberry Pi ?

The common question that most people ask is: What is Raspberry Pi used for ?

The obvious answers are the projects that can be built up using the Raspberry Pi. Due to its low-cost, it can be used for any school level or even college level project in the field of Computer Science and Electronics. The sky is the limit when finding the uses of the Raspberry Pi board. The original goal for founding the project was to help children learn Computer Science in a cheap and easy way, making the RPi helpful for education of the poor. Now they can be used to make standard media players or even more complex objects like robots that can do many different tasks. The main point is taking advantage of its size and portability to perform these projects. Let's see some awesome projects made using the Raspberry Pi:
