Technical Aspects

10. How it differs from other Board
Low power consumption
PC takes 65-250W
Laptop takes 15-60W
Low cost
Small in size

11. HOW IT WORKS
 Begin by slotting your SD card into the SD card slot on the Raspberry Pi, which
will only fit one way.
 plug in your USB keyboard and Mouse into the USB slots on the Raspberry Pi.
Then connect your HDMI cable from your Raspberry Pi to your monitor or TV.
When you are happy that you have plugged in all the cables and SD card required,
finally plug in the micro usb power supply. This action will turn on and boot your
Raspberry Pi.
If this is the first time your Raspberry Pi and NOOBS SD card have been used, then
you will have to select an operating system and configure it. Follow the NOOBS guide to
do this.

12. logging into RASPBERRY PI
Once your Raspberry Pi has completed the boot process, a login prompt will
appear. The default login for Raspberry pi is username pi with the password
raspberry. Note you will not see any writing appear when you type the
password. This is a security feature in Linux.
After you have successfully logged in, you
will see the command line prompt
pi@raspberrypi~$
To load the graphical user interface, type
startx
and press Enter on your keyboard.

13. Programming with RASPBERRY PI
Here’s the code to print out a message to the screen:
#include <iostream>
using namespace std;
int main()
{
cout << "Hello Raspberry Pi!" << endl;
return 0;
}
It’s a simple C++ code to print a message

14. COMPILING and RUNNING
So, take the above code and paste it into a file called 01_HelloRPi.cpp. Now
open up a command prompt and navigate to the directory that contains the file.
In the command prompt type:
g++ -std=c++0x 01_HelloRPi.cpp –o01_HelloRPi
This will take the code that you have written and create a program that can run.
The name of the program to create is specified with the –o flag, in this case we
called it 01_HelloRPi. The –std=c++0x flag tells the compiler to use the latest
version of the c++ standard. Then to run the program type in:
./01_HelloRPi
And that will write your message to the screen.

15. Handling the RP
-The Raspberry Pi was built to be used, but not abused. Every
Printed Circuit Board (PCB) should be handled with care.
-Handle the RP only by the edges of the board itself.
Avoid touching or holding any of the components on the
board.
-Rough handling can damage solder points and may also lead to
short circuits, but be careful with the GPIO pins as well.

16. Applications
Home Automation System.
Home Security System.
HD surveillance Camera.
Media Center.
Mobile device.

17. RP Mobile
HD surveillance Camera

18. DISADVA
NTAGES Although, we use it as a desktop computer . It’s power is closer to a mobile device
(like a TABLET) than a modern Desktop PC.
 The Graphics capabilities lag behind the today’s market (Modern Computers).
 It can’t add more RAM.
 Can’t support WINDOWS OS.

19. Future
ScopeAdvanced Power Options.
 Increasing Memory.
 Supporting maximum number of Operating systems.
Inbuilt Hard disk facility.
Raspberry pi 2020

20. Raspberry pi 2020
 8 cores, improved GPU, 8 GB Main Memory.
 WiFi, Camera.
 Match box sized case.
 Holographic Laser projector, Virtual Keyboard.
 <$25 cost.
and more…….

21. Conclusion
Raspberry Pi is an innovative product.
Increasing the processing power can surely help the product in the future.
Thus we can expect a HUGE REVOLUTION in the field of Computer Science in the
coming generations…
