The Raspberry Pi is a credit-card sized computer that can be used for tasks like spreadsheets, word processing, and playing videos. It was founded in 2006 by Eben Upton to improve computer science education. The Raspberry Pi has a low cost, supports many programming languages, and has inputs/outputs that allow users to control electronics. Examples of its applications include robotics projects, running experiments in space, and disaster relief drones. The Raspberry Pi Foundation aims to improve the device and make it accessible to more users worldwide to learn programming.

3. INTRODUCTION
 The Raspberry Pi is a credit-card sized computer that plugs
into your TV and a keyboard, which can be used for many of
the things that your average desktop does - spreadsheets,
word-processing, games and it also plays high-definition
video.
 The Raspberry Pi charitable foundation wants to see the
device being used by kids all over the world to learn
programming and electronics.
 Its 17 GPIO(General Purpose Input Output) pins can be used
with actuators and sensors for different embedded
applications.

4. Very low cost (Rs.1500 to Rs.3000 ).
Great tool for learning programming , computers and concept of
embedded systems.
Support for all age group (School children , college undergraduates ,
professional developers and programmers. )
Consumes power less than 5W.
WHY RASPBERRY PI ?

5. HISTORY
Founded by “Eben Upton” at University of Cambridge.
That time ( in 2006) he was concerned about the year-on-year decline in
the numbers and skills of students applying to read computer science.
Academic project for UK students
It was a teaching aid in school and colleges
In Aug. 2011 , 50 Alpha boards released
Initial sale Feb 29. 2012, went with 2 million orders

12. GENERAL PURPOSE IO (GPIO) PINS
17 GPIO pins brought out onto the P1 header
 most have alternated functions
 two pins for UART; two for I2C; six for SPI
All 17 pins can be GPIO (i.e., INPUT/ OUTPUT)
 all support interrupts
Pins are 3.3V not 5V like on the Arduino.
They are connected directly to the Broadcom
chip .Sending 5V to a pin may kill the Pi. Maximum permitted
current draw from a 3.3V pin is 50mA.

13. APPLICATIONS
 Raspberry pi is powerful enough to be used as a personal computer.
 The best application is learning different programming languages like Scratch,
Python, C++ etc.
 Scratch is a visual programming tool allowing the user to create animations and
games with a drag-and-drop interface.
 The General Purpose Input / Output pins allow you to control and interact with the
real world from Python, Scratch or other programming environments.
 Different robotics and embedded system projects can be made, easily by
programming the GPIOs, for students and professionals.

14.  The raspberry pi has better future scope because its limitless applications.
 The foundation wants to improve pi so that it could be used by every electronics and
computer science lovers.
 There are many ongoing projects using raspberry pi whose outcomes will be beneficial
to students or to common man.
 “A project called Openrelief is building an autonomous flying drone which uses
Raspberry Pi as its core technology to provide help for the disaster relief organizations
and develop communications tools.”
 “ Astro-pi ” is also a similar on going project. The pi has been sent to
INTERNATIONAL SPACE STATION with some astronauts by UK Space Agency
because of its compactness and unlimited applications to run experiments using the
unique environment of space and to try new technologies that may become crucial
when humans begin to visit other planets such as Mars.
