2. • Series of single-board computers
measuring
approximately 9cmx5.5cm
• A credit card sized PC
• Designed for education
• Complete easy-to-program computer

3. • Developed by Raspberry Pi Foundation in United
Kingdom
• Created in 2012 in UK supported by University of
Cambridge Computer Laboratory and
tech firm Broadcom
• To promote the teaching of basic computer
science in schools and in developing countries

4. • 10/100 Base T Ethernet Socket
• HDMI Socket
• SoC is a Broadcom BCM2835
• USB 2.0 socket
• GPIO
• SD card socket
• LAN Controller
• Header footprint for camera connection
• RCA video socket
• 3.5mm Audio standard headphone socket
• Powered from micro USB socket
• JTAG
• DSI

6. • Credit card sized
• Low cost (Model A --$25, Model B-$35)
• Ultra low power~1W
• Not required to purchase any special license from the
Raspberry Pi Foundation to use their product
• Perfect for adaptive technology
• Able to display images or videos at 1080p high resolution
• Energy efficient
• Easy to recycle and does not release as much carbon dioxide
emission into the environment

7. • It does not replace computer
• Unable to do any complex multitasking
• it cannot run X86 operating systems
• There is no real time clock associated with the board
• Processor is not as fast
• This product will not be useful for bigger businesses

8. • It’s a Mini computer which cost is cheap
• Make a old TV into a smart TV
• Connect with Monitor, Keyboard, Mouse
• Teaching programming concepts
• Can be used in robotics for controlling motors, sensors
etc
• It can act as Full HD 1080p Media Player
• Teaching hardware interfacing

9. Application of raspberry Pi
IS
Electronic Voting Machine(EVM)

10. • For corruption free voting system
• For gaining trust through a transparent voting
system

11. • Two layers of protection
 User has to proving himself as candidate
& without the finger print of candidate voting machine
will not
be unlocked
 After unlocking the user will submit his vote through
push
button & machine will be unlocked again

13. • Input device
 Wifi camera
• Processing unit
 Raspberry pi
 NRF24L01 Transciever
 Wifi USB Dongle
• Output device
 20 x 4 lcd display
• Operating system
 Linux

14. • Atmega16 Microcontroller
• NRF24L01 Transciever
• Finger Print Sensor
• Lcd
• Piezo Buzzer
• SD card memory
• Push Button

15. Raspberry Pi:
• It is heart of this application
• NRF24L01 transciever,Wifi dongle,
LCD display connected with it
• Wifi-dongle will connect with the USB
port in it foe data communication
• LCD display connect with GPIO

16. NRF24L01 transciever :
• Can communicate with 6 devices at a time
• Connect with the micro-controller’s
MISO,MOSI,SS pin and
micro-controller and raspberry Pi
have also the same pin
• Connected with raspberry Pi for
communicate with it

17. Atmega16 Microcontroller:
• Push buttons of voting machine is connect with
PortA and led with PortC
• Finger print sensor’s RX pin is connect with TX
pin of it
• NRF24L01 transciever connect with MISO,
MOSI,SS pin

19. National Id Card number is
captured by webcam & crop the
number
After converting & removing
noise then binary image it looks
almost same

20. Saving the number
in english in excel
file
Sent it to database
and find location and
already voted or not

21. After verification,finger
print also verify and
match with database,
then unlock the voting
machine unless it will
be locked
After each vote the
system transmits an
update to tweeter
and update database

22. Base Station Voting Machine

23. • Corruption can be minimized through honesty and
sincerity. This system is a small contribution for a fair
election
