Raspberry Pi – A Big Revolution In Technology
The raspberry pi brought revolution in technology. It gives us excellent innovation in the field of technology. The Raspberry pi is the first smallest computer developed in United Kindom. It is developed by Raspberry Pi Foundation. This smallest computer size is equal to the credit card.It is not only smallest single board computer, is also inexpensive. It was an initial sale in just $10 rupes.
In very start, Raspberry Pi Foundation used it for teaching basic computer science in developing countries. Because the buying power of peoples in developing countries is low, therefore it was decided to build the cheap computer that purchased low budget people.
According to Raspberry Pi Foundation : We provide low-cost, high-performance computers that people use to learn, solve problems and have fun. We provide outreach and education to help more people access computing and digital making. We develop free resources to help people learn about computing and how to make things with computers, and train educators who can guide other people to learn.

Raspberry Pi projects
As we know that in start, raspberry pi single board computer used for the purpose of teaching computer science. But with the passage of time its demand increase in different scientific projects. This single board computer now a days mostly uses as the embedded device in multi-projects.Raspberry pi brings revolution in technology and different projects are made on it. Lets see some of the famous raspberry pi projects.
Stratux
Stratux is a project which uses raspberry pi 3 single board computer. Stratux is used to provide information about the various aircraft in the sky around you.
3D SCANNER
Raspberry pi uses in 3D scanners. By using 3D scanner can capture a complete 360 degrees image of any object up to and including a human-sized one.
Xbox Zero
Raspberry pi zero is using in Xbox Zero. Terence Eden put raspberry pi zero inside an original Xbox controller.
Whatsapp
Whatsapp is a well-known instant chat application. You can run this application on a raspberry pi. For installation, you need to enter few line of code.
