RASPBERRY PI For Beginners  

 By Johnson Augustine

You can make stuff that will have other people looking on jealously, and that will make you feel wonderfully smug all after noon.”

Eben Upton - Co-Creator of Raspberry PI Embedded Board.


Today world, small things make big changes to the entire world and change an era.  Now a day’s most of the new inventions are came from teen age peoples and youth. They are always thinking for a change especially in Information technology and Electronics. Things are changing from big to small and small to very small and to invisible but we can feel the presence, technologies are expanded in this ways. No need to sit in a place everything can be controlled when we are moving. I saw a software called KTS Info mate, and in that we can control more than 100 display screens [Digital notice Board ] and set different contents while we are moving .This is a great technology and may be a new invention for the world .

                If we talking about embedded boards and tiny computer devices, there are lot of experiments are going on .and lot of new boards and tiny computer systems are available now in market with great operational facilities and functions. And the great advantages of these are, it has only less cost .

Here I like to introduce a new board called as “RASPBERRY PI “in to your front. And  I am making things with this .

What is Raspberry PI

Raspberry PI is a tiny  embedded board .The processor at the heart of the Raspberry PI is Broadcom BCM2835 system on chip(SoC)  ARM x86 processor. The early stages the name of raspberry PI project was “ABC Micro”  But later the name is finalized in to “RASPBERRY PI” .Why  Raspberry , because there’s long tradition of fruit names in computer companies , And PI is a mangling of Python . The project team thought that on the early development would be the only programming language available on a less powerful platform  than the Raspberry PI they ended with .

Server Support: Apache Server, Mono server for  run C# 2.0 based web apps and it supports jquery and ajax .


What you can do with Raspberry PI ?


You can use Raspberry PI for controlling motors, machines and do robots with the help of GPIO facility provided by its developers . You can also use this as a tiny web hosting server to host your websites developed in php or 2.0 and provides supports for jquery and ajax. You can run applications and stand alone Apps developed in c/c++/C# or python to do your jobs .



Getting started with PI

Now you have a basic understanding of how the PI differ from other computing devices and it’s the time to get started .If you’ve just received your pi , take it out of its protective  anti-static bag and place it on a flat, on-conductive surface.

Connecting Display

Composite video connector RCA phono connector – Yellow silver port at the top of the PI  for connect the display to a TV or CRT Display.

HDMI Video : The port will found on the bottom of the pi , it will give Full HD display [1920*1080 resolution ] .

DSI Video : The port found the top of SD card slot , will able to connect a small ribbon connector protected by a  plastic and this is for a video standard called DSI[ Display serial Interface ].

Connecting audio : There is an audio jack for connect speakers , if you are using HDMI then no need of this because it will transmit both audio and video.

Connecting key board and mouse: You can connect keyboard and mouse to USB port.

Connecting Camera : You can connect any USB camera to Raspberry PI , But don’t forgot to use an external powered  USB Adapter to connect the camera to PI [ Don’t connect directly ]

Downloading Raspberry PI OS : Download latest version of Raspberry PI OS from

Writing the image to Disk.

Flashing from Linux:

Open a terminal from linux

Insert SD card in to your card reader connected to system

Type fdisk –l  will list all storage , Note that the SD card name may be /dev/sdX where X is the letter for identifying your storage , some machines have built in SD card reader and might be displaying different names that I specified here [ eg /dev/mmcblkx ]

Use cd to change the directory which contains the disk image

Type  “sudo dd if=<imagefile.img> of=/dev/sdX bs=2M “ .  This will write your files to the SD card might be take long time to complete the process.

Flashing from OS X

If your system running Apple OS X , It is very simple to do the operation .

Select the utilities from the application menu and click on terminal application .

Insert your blank SD card in to system card reader

Type diskutil to display all storage devices and note the name of your SD card

Unmount the disk if already mounted in to your desktop by typing the command  

“diskutil  unmountdisk  /dev/diskX”

Use cd to change the directory which contains the disk image

Type dd if=<imagefile.img> of=/dev/diskX  bs=2M to write the image to SD card

Flashing from Windows

To flash from windows download  win32 Disk manager or win32 disk writer

Click on the exe and insert the SD card to card reader

Select the image from the directory , select the SD card from droup down list [ Right]

Click write to write the disk image

Backing up your PI SD card as image[ .img ]

To flash from windows download  win32 Disk manager or win32 disk writer

Click on the exe and insert the SD card to card reader

Type any name the path selection  textbox and don’t forgot to give .img extension

Eg : imagebackup.img

Click on read to backup your image


Connecting external Storage

To connect external storage  to USB and mount the device to PI. If you are using LXDE desktop this will be get done automatically else you have to manually mount [Make the device known to the Os] .For this

Connect the USB Disk to a external Powered  USB hub .

Type fdisk –l  to get  all device names and find your external storage [Eg /dev/sda1 ]

Before mounting you have to create a mount point , becaue linux needs a mount point before accessing a usb storage device

Type sudo mkdir /media.externaldisk

Currently the access right is assigned to root only so change the rights to all users of pi

Type this in a single line “sudo chgrp –R users /media/externaldisk && sudo chmod –R  g+w /media/externaldisk “ .

Mount the USB device by typing the command

Sudo mount /dev/sdXN      /media/externaldisk –o=rw


Connecting PI to a network

We can connect the PI by using Built in Ethernet port[RJ45]  or using a USB 802.11n Wireless network [Wifi ] . When you connected it will obtain an IP automatically because a DHCP is enabled in Network of pi . Wifi dongle is only available with Model A ,If your PI is model B then you have to purchase any usb wifi dongle that supports  linux debian .

Connecting two PI through network

To make a connection between two Pi  you have to use a cross over able for that and connect to RJ45 port of both
