Raspberry pi ! A Brief Introduction for beginners

Introduction of Raspberry pi 3:

   Raspberry pi 3 is a Credit card-sized, Linux-based, single board type computer. Its first generation was released in Feb 2012 which was basically created for kids' educational programming and the third generation which is raspberry pi 3 is used as an affordable platform for learning how to code. 

Raspberry pi

Creators of the pi board:

Raspberry pi was created in the United Kingdom by the Raspberry Pi Foundation in association with Broadcom. We created the Raspberry Pi project with the intention of encouraging the coaching of primary pc technology in faculties and deprived countries. The initial model was more popular than expected, selling for uses such as robotics outside of its core market.

                  Following the release of the second board type, the Raspberry Pi Foundation established a new organization called Raspberry Pi Trading, with Eben Upton as CEO with responsibilities of technical development. The Foundation was re-established as a charitable organization dedicated to promoting the teaching of basic computer science in schools and in poor nations. The majority of Pis are produced in a Sony factory in Pencoed, Wales, with the remainder being produced in China and Japan.

Components/ specifications:

        Even though the raspberry pie is a little over 3 inches by 2 inches it has all the components of your typical computer. It has

     Quad-core 64-bit ARM cortex 853 processor running at 1.2 gigahertz which is about 50 percent faster than raspberry pi 2.

     2.5 amp micro USB power input

     Full-size HDMI output.

     Combined 3.5mm audio jack and composite video

     Video core IV 3D graphics core

     1GB LPDDR2-900 SDRAM

     40 GPIO (general purpose input-output) pins

     10/100 Ethernet port

     4 USB 2.0 connectors

     SD slot for the micro SD card

     802.11n Wireless LAN

     Bluetooth 4.1

     1GB LPDDR2-900 SDRAM

     CSI port

     DSI (Display Serial Interface) port

     Built-in chip antenna which connects to the built-in Wi-Fi to the back of the board.

Operating system:

You will need SD card with the operating system downloaded to it in order to start using your pi. There is a number of operating systems you can install i.e.:




     Ubuntu MATE

     Kali Linux

     Windows 10 loT

     Arch Linux ARM

     Android things

     Free BSD

     Net BSD


Recommended OS:

        Raspbian is the most basic version of a desktop that you can have on Raspberry Pi running directly from it. As a matter of fact, Raspbian was built for the Raspberry Pi as a Linux distribution that works light and fast. So what can you do with a Raspbian desktop, well anything that you can do with a regular computer? You can run their own version of an audio player, you can watch videos, you can even play some games that run on python and many other things on the raspbian platform.

         In addition, you can also install a lighter version in your raspberry pi called Ubuntu MATE. Now there are many different types of OS you can use in your raspberry pi 3 but the recommended one is Raspbian.  

Programming language:

    Programming languages you can get on the raspberry pi 3 are python, scratch, c++, pearl, java, HTML5


        The ‘PI’ in the raspberry pi 3 stands for python that is why it is the most recommended one. Particularly great for newbies or general pi users or for those who want to refresh their programming knowledge.

 Key applications of raspberry pi 3:

 Raspberry pi offers a list of applications and can be used in electronics projects and for a number of things, i.e.:

     Home automation and home security

     Weather station

     Retro gaming console

     3D printing

     Smart door locking


     DIY projects


     Media center


How do I get started?

To get started with your raspberry pi 3 you will need:

     A monitor or TV screen

     A mouse

     A keyboard

     Noobs card or an SD card with the latest version of New Out of Box Software (NOOBS)

     2.5-amp power adapter

     Pi case.


Putting the pi in the case:

Before I set up the pi 3 let’s put it in the case to protect it.

     The case has been newly designed and comes in five parts: a lid, the top, two sides, and the bottom.

      The bottom has a cut-out for the micro SD card. When you put the pi into the case, make sure, you give it a little angle so the SD card fits through. That's convenient in case you want to use different SD cards as you use your pi.

     Also, make sure that the four standoffs on the bottom of the board line up to the through holes on the raspberry pi,

     Next, we put it on the top. The top is cut through to accommodate the Ethernet and the four USB ports and it snaps on.

     Next, we will put the sides on. One side is open so that you can have access to the GPIO pins the side snaps on.

     The other side has cutouts for your power, your HDMI out, and your 3.5 mm jack.

     Finally, we will put it on the top, and there you have a very protected pi.


Connect the peripherals:

     The first thing you will do is hook up the mouse keyboard and monitor.

     Connect your wired keyboard mouse and keyboard with the USB connectors and then connect those right into two of the USB ports on the pie and you still got two more ports for other accessories.

     Next, take an HDMI cable and connect it into the HDMI out of the pi and then connect the other end to your HDMI monitor

     Insert your micro SD card which should be pre-loaded with the new out-of-box software ‘noobs’. Noobs help you set up your pi and make it easier for you to install OS. 

     Download your operating system. Recommended one is raspbian, an open-source debian Linux OS. 

     You can access programming languages, office-type applications, accessories, tools, file managers.

     The next thing you will do is configure the pi 3 to your local time country and area.

     You don't need an Ethernet cable to connect the Wi-Fi in the raspberry pi3. Just select the network for the top-right menu bar of the network icon and you are ready to go.

Power consumption of raspberry pi 3:

The max power consumption of the pi 3 under excessive load is (750mA vs 360mA) which is nearly double the pi 2, though it should be comparable to earlier boards for less-demanding workloads.

Can we use it as a PC desktop?

If you have the patience, you can use the Pi as a low-cost desktop computer. However, don't expect the Pi 3 to perform as well as a standard PC; it may lag while loading heavy pages, and having more than a handful of tabs open at once risks overwhelming the Pi's memory, resulting in a prolonged freeze.

Can we use a browser on raspberry pi 3?

The Chromium browser, on which Chrome is based, is included in the current version of the Raspberry Pi's official OS. It runs smoothly as long as you don't open too many script-heavy websites, and there are plugins that enable smooth video playback on YouTube and other websites.

Size of micro SD card:

For official raspbian OS, you will need at least an 8GB micro SD card while for raspbian lite you will need a 4GB micro SD card.


Models after raspberry pi 3:

There are several models which are launched after raspberry pi 3 which are raspberry pi 3 B, B+, raspberry pi 4, raspberry pi zero, raspberry pi Pico.

How do I keep up my raspberry pi 3 updated?

Keeping the Raspberry Pi up to date is extremely simple if you're using the official Raspbian operating system. Simply type ‘Sudo apt-get update in the terminal. When the update is finished, run sudo apt-get dist-upgrade.
