Raspberry Pi

The Raspberry Pi is a series of small single-board credit-card sized computers developed in the United Kingdom by the Raspberry Pi Foundation to promote the teaching of the basic computer science in the schools and in the developing countries. The Raspberry Pi can be plugged into a computer monitor or TV and uses the standard keyboard and mouse. It is a capable little device which enables people of all ages to explore computing and to learn how to program in languages like Python and Scratch. It is capable of doing everything you would expect the desktop computer to do, from playing high definition video, browsing the internet, word-processing, making spreadsheets, and playing games. The Raspberry Pi has the ability to interact with the outside world which has been used in the wide array of digital maker projects, from the music machines and parent detectors to weather stations and the tweeting birdhouses with the infra-red cameras.
