Ongoing Project

Hey Fellas Started persistence of vision Using Raspberry

Keep ur finger crosed !!
For viewing Colourful and speeding Output!!!!

Need ur Projects to be done???

Current Project.
Developed a security system which alerts the user by sending SMS when ever human or fire is detected.
The user can view the place from any part of the world where the device is placed.
Video will be recorded for a specified duration when the human or fire is detected,which can be used for investigation purpose...
                  Main moto is to done all these things @ minimum cost price ...
Your Ideas for the next project are welcomed :)

Controlling GPIO pins of Pi online

Here comes the answer for ur queries.

How to control GPIO pins of Pi online?You can use WebIOPi for this
Steps.1
$ tar xvzf WebIOPi-x.y.z.tar.gz

$ cd WebIOPi-x.y.z
$ sudo ./setup.sh

This wil install the WebIOPi

Commands to Start and stop are given below respectively

$ sudo /etc/init.d/webiopi start
$ sudo /etc/init.d/webiopi stop

If u need ur Raspi to run Webiopi @ boot itself the use bellow code
then reboot ur pi

To setup your system to start webiopi at boot :

$ sudo update-rc.d webiopi defaults
Code for rebooting
sudo reboot

To remove webiopi start from boot :

$ sudo update-rc.d webiopi remove

this will be implemented after ur boot

Once u Webiopi is ready to use
You control it from the URL
IP of PI:8000
It will ask for User and Password
user : "webiopi"
password is "raspberry"

By choosing the GPIO Header link on the main page, you will be able to control GPIO using a web UI which looks like the board header.

• Click/Tap the OUT/IN button to change GPIO direction.
• Click/Tap pins to change the GPIO output state.

Using this u can build ur Home Automation system..

Now the pic is captured :) :) :) Smile please :)

Acessing Internet in Pi

Hello Folks!!!!
Its time to browse via Pi.

All u need is...

1.Modem -1

2.LAN Cable -2

Steps for enabling internet

1.Initially ur pi runs on static IP

inorder to connect it with inernet

@Pi Terminal type the following command

code:”sudo nano /etc/network/interfaces”

change the following things

Now save it by pressing ctrl+x

give y and press enter!!

now Reboot ur pi 

code:"sudo reboot"

2.Now connect ur Pi with Modem using LAN cable and Pc to Modem using other LAN

3.Now u can browse in internet...

Now IP address of pi is assigned automatically and it is not constant..

Njoy browsing via pi!!!!!

            In the next post lets see How to capture a picture from Pi using normal Web Cam ......

Remote acess with Linux

Hi viewers!!! in this one lets c how to connect raspberry with Linux

Things to do
1.Connect your PC or Lap with ur Pi directly ie) from on point to lap and other to the kit              
              Once u started Linux in Terminal (The terminal can be obtained by pressing ctrl+alt+del)
2.First install nmap for finding ip of Pi
code "sudo apt-get install nmap"
3.Find the Ip of pi by running the following code in terminal
code "sudo nmap 192.168.1.* "
 or
      "sudo nmap 192.168.0.* "
4.Make sure that ur pi is SSH enabled
  Now run the following code to obtain pi terminal
code"ssh pi@IP of pi"
5.login the pi by providing username and password

FOR OBTAINING SCREEN OF THE PI
 In Pi terminal
1.Install tightvncserver
code"sudo apt-get install tightvncserver"
2.code"vncserver :0 -geometry 1024x768 -depth 24"
 In System Terminal
1.Install xtightvncviewer
code"sudo apt-get install xtightvncviewer"
2.code"xtightvncviewer IP of Pi"
Pi screen will apear...

In the upcoming post...Lets c how to enable internet in Pi

Dont u have HDMI nor TV nor any monitor.?????
              Dont worry Here is the solution for ur prob...
U can use ur Lap r PC as monitor of PI just by using ur LAN cable
To connect ur Pi with PC in Windows Xp and XP+ versions..
Required Thngs 
1. LAN Cable
2.IP Scanner
Download
3.Putty
Download
4.Ximing
Download


STEPS
1. Run the Ip scanner
Scan for IP in the range 192.168.0.0 to 192.168.255.255
from which u can able to view the IP of ur Pi
2.Run Ximing
3.Run ur putty

in the Host name type ur IP address of the pi..before that be sure that SSH is enabled in ur Pi

i )select only on clean exit
ii)click on  X11 under SSH and select checkbox Enable X11
iii)Now open
A screen opens ask for username
give it as follows
 Loginas: pi
 Password:raspberry(when u type the password the characters are not visible) just type it and press enter.
it asks a permision just give Yes

Now terminal of Pi appears  just give the command as lxsession in the terminal now u can view ur pi screen in ximing window :)

In the next post let me tell u how to login remotely in Linux ....
   

Booting ur pi @ 1st

Lets start from the scratch....
           In this we gonna see How to Boot the Pi..
All u need is
