Install an OS
 Raspberry Pi is a fully blown computer
 Operating Systems
• Raspbian (Optimized for RPi)
• How to install Raspbian
1. Use NOOBS
2. Use NOOBS Lite
3. Download only Raspbian image file
 NOOBS
• An easy operating system installer which contains Raspbian
 OS & NOOBS download site
• https://www.raspberrypi.org/downloads/

4
Install the OS
 Raspbian will be stored in a Micro SD card
 Connect Micro SD card to SD card reader
• Micro SD card can not be connected to the PC without SD card reader

5
Install the OS
 Using NOOBS vs Downloading Raspbian Image

6
Install the OS - Raspbian
 Download the NOOBS or the Raspbian image file
• https://www.raspberrypi.org/downloads/noobs/
• https://www.raspberrypi.org/downloads/raspbian/

7
Install the OS - Raspbian
 Unzip the file
• It includes Raspbian image file

8
Install the OS – Writing image to Micro SD card
 Need software to write the Raspbian image on to the MicroSD card
 You can download and use Win32 Disk Imager for this.
• https://sourceforge.net/projects/win32diskimager/

9
Install the OS – Writing image to SD card
 Set up Win32 Disk Imager

10
Install the OS - Writing image to SD card
 Write an image file to Micro USB

12
Boot your Raspberry Pi
 Booting into GUI

13
Connect your Raspberry Pi to the Internet
 Connecting via Wi-Fi
• A Raspberry Pi 3
− Built-in Wi-Fi
• An earlier version of the Raspberry Pi
− Need a Wi-Fi Dongle
• Some Wi-Fi dongles are simple plug and play devices
− Others require specific drivers, and may not be compatible
− Read the device manufacturer’s documentation

14
Connect your Raspberry Pi to the Internet
 Connecting via Ethernet
• RPi has an Ethernet port beside the USB ports
• You can connect to a network using an Ethernet cable
− A router, access point, or switch

15
Korean Language setup
 In order to input commands to Raspbian, start LXTerminal application
 Make sure your device is connected to the Internet
 Download & Install Korean (Hangul) Fonts if you wish to use Korean
fonts in addition to English
• Download a package by updating and upgrading the system
• Install Korean (Hangul) fonts
$ sudo apt-get install ibus
$ sudo apt-get install ibus-hangul
$ sudo apt-get install ttf-unfonts-core
$ sudo apt-get update
$ sudo apt-get upgrade

16
 Raspberry Pi Configuration
• [Menu]  [Preference]  [Raspberry Pi Configuration]

17
 Language and country setting
• [Localisation]  [Set Locale]

18
 Timezone setting
• [Localisation]  [Set Timezone]

19
 Keyboard setting
• [Localisation]  [Set Keyboard]

20
 Let’s reboot!
• After finishing all setting up, then reboot the RPi
• Notice that the menu in English has changed to Korean
 Check the keyboard
• Toggle the language [US  Hangul]
• Click the Hangul
• Now you can toggle the language [Shift + Spacebar]

21
Headless setup
 It could be very inconvenient
• If you need to connect monitor every time you use the RPi
• Often, you may not have an extra HDMI cable or keyboard
 It would be very convenient
• If you can access the RPi without its own monitor or keyboard
 Headless Raspberry Pi
• Use VNC (Virtual Network Computing) software for remote (headless) login
• VNC server/client software needed

22
Headless setup – Working PC
 Download VNC (Working PC)
• http://www.realvnc.com/download/

23
 Install VNC
• Select VNC viewer, not VNC server

24
Headless setup – Raspberry Pi
 Check IP address (Ethernet)
$ ifconfig

25
 Accessing the Raspberry Pi remotely
1. Creating a new screen every time
2. Sharing one screen
 When creating a new screen every time for each user
 Run VNC server on the Raspberry Pi
$ sudo apt-get install tightvncserver Install VNC (Raspberry Pi)
$ vncserver :1

26
 Access the Raspberry Pi via VNC viewer

27

28
 Install VNC server
1. Creating a new screen every time
2. Sharing one screen
 When sharing the one screen
 Run VNC server on the Raspberry Pi
$ sudo apt-get install x11vnc Install VNC (Raspberry Pi)
$ x11vnc

29
 Access the Raspberry Pi via VNC viewer

30
Headless setup
 Now you can access the RPi without an extra monitor and keyboard

31
Summary
 Explained the hardware requirements for getting started
 Explained major parts of Raspberry Pi 3 Model B
 Explained two methods for installing Raspbian operating system on the
Raspberry Pi
 Explain the concept of “headless setup” and how to achieve it using
VNC server and client
