Setting Up Raspberry Pi 3

Introduction: Setting Up Raspberry Pi 3

The Raspberry Pi is a low cost, credit-card sized computer that plugs into a computer monitor or TV, and uses a standard keyboard and mouse. It is a capable little device that enables people of all ages to explore computing, and to learn how to program in languages like Scratch and Python. It’s capable of doing everything you’d expect a desktop computer to do, from browsing the internet and playing high-definition video, to making spreadsheets, word-processing, and playing games.

What’s more, the Raspberry Pi has the ability to interact with the outside world, and has been used in a wide array of digital maker projects, from music machines and parent detectors to weather stations and tweeting birdhouses with infra-red cameras. We want to see the Raspberry Pi being used by kids all over the world to learn to program and understand how computers work.

Step 1: Components Needed

1. Raspberry Pi 3 .

2. 5V , 2A adapter with mini usb cable .

3. HDMI cable .

4. USB keyboard and mouse .

5. SD card minimum 8GB class 10.

6. Ethernet cable (optional) .

Connect the keyboard and mouse to your Pi USB ports . Connect the Pi to an HDMI supported TV using the HDMI

cable. If you want to use wireless keyboard and mouse then connect its wireless dongle to the USB port of Pi . Dont

power up your Pi now !! cz Before powering up we have got a job to do ;)

Step 2: Installing Operating System

The first step to start with Raspberry Pi is to install an operating system . Just like our PC needs an operating

system , our Pi also needs an operating system to work . Our SD card acts as the hard disk of Pi , where we install

the OS . There are wide variety of OS available for PI . But we start with the OS called Raspbian. For beginners I

recommend NOOBS to install OS in our Pi . NOOBS is a software that guides you to install various OS available in

the market .

install NOOBS from this link :

Step 3: Setting Up the Full Hardware

Now you have a keyboard , mouse , HDMI display connected. You installed Raspbian . Now what's left !?

An internet connection ofcourse ! Raspberry Pi 3 comes with inbuilt WiFi so you can connect it to any wireless

network just like your mobile and laptop . Or you can use ethernet cable to connect to internet using any modem.

It also has inbuilt bluetooth .You can easily send and receive files using bluetooth. Pendrives can be connected just

like in PC and files can be accessed and transferred . Find your USB drive inside /media folder .

Step 4: Some Useful Commands - Pi 3 Terminal

Terminal can be opened using control + alt + F1/F2/F3 anytime .

open the terminal and enter the following commands

sudo raspi-config

to configure Pi like changing password for the user etc .

sudo startx

to see the desktop of Pi .

sudo apt-get update

to check for updates and install them in Pi


to list the files in the current directory

cd /

to go to root directory


to go to previous directory

cd <name>

to go to a particular directory

Step 5: Setting Up Display for Pi 3

You see you always need a display to work with Pi . But you cant take an HDMI display like TV with you all the time

!! So you need a solution for this . The best solution is getting your Raspberry Pi display onto your laptop. But you

cant do it using HDMI port of the laptop because it is an output port . So dont try it ! There are 2 solutions to access Pi remotely :

1) Putty

2) VNC server software

Putty is used to remote access Raspberry Pi . Just power on your Pi . Be sure that your laptop/PC is connected to

the same WiFi network as the Pi . First you have to find the IP address of your Pi using this terminal command :

sudo hostname-I

Install Putty in the laptop from - .

Open it , you will see a putty configuration window , go to session , set the IP address as your Raspberry Pi's IP

address and the port as 22. Save the session and press okay ! Now login with the password of your Pi . Now you

can access your Pi using the Putty's terminal ! It just acts as the Pi's terminal .

But still we don't have access to Pi's desktop in our laptop . Lets see how to bring Pi's desktop to our laptop screen.

For that we have to install something called VNC server in both Pi and Laptop .

For complete steps go to link -

Another method to bring Pi's desktop to laptop screen is by using Putty + Xming server . It is faster , but the

desktop is a customized one different from original Pi and not graphically attractive .

Step 6: Thats All Folks !!

So thats all ! thats how simple is to setup a raspberry pi 3 . You learnt how to install operating system , setting up

internet and mirroring Pi desktop to laptop screen . More tutorials are available in internet which guides you how to

install new applications in Pi , program Pi , set up media center etc. Now you own a pocket pc on your palm . Be

proud to be a Raspbian ;)

    i am using R pi 3 and it is booting serially via usb to ttl using putty software .it is running successfully.

    But when i connect to my monitor via vga to HDMI converter my monitor screen blinks 1 0r 2 times and nothing show on screen.

    i know i have to edit config.txt can you tell me what i have to change in config.txt file.

    Hm I am sorry I haven't used VGA HDMi converter with Pi. So I don't know about it . Instead of that I found it very simple to use the VNC server to "screen mirror" the display to laptop / PC connected to same WiFi as that of Pi :-)
