 Inexpensive(ish) ~$35 each
 Capability:
 Programming
 Electronic Projects
 Office
 Play HD Videos

VARIATIONS OF RASPBERRY PI
 Hardware platform
 Raspberry Pi Zero ($5)
 Raspberry Pi
 Raspberry Pi 2
 Raspberry Pi 3 (with
Wifi + Bluetooth)
 Software platform

• Essential:
– Raspberry Pi board
– Prepared Operating
System SD Card 8GB
– USB keyboard
– Display (with HDMI,
DVI, or Composite
input)
– Power Supply
• Highly suggested
extras include:
– USB mouse
– Internet connectivity -
LAN cable
– Powered USB Hub
– Case
Kit Components

PROGRAMMING LANGUAGES
 The Raspberry Pi Foundation recommends
Python
 Any language which will compile for ARMv6 can
be used
 Installed by default on the Raspberry Pi:
 C
 C++
 Java
 Scratch - Scratch is a visual programming language
and online community targeted primarily at children
 Ruby - Ruby is a dynamic, interpreted, reflective,
object-oriented, general-purpose programming
language. It was designed and developed in the mid-
1990s by Yukihiro "Matz" Matsumoto in Japan.

LINUX
 Interesting, powerful
 Variations (Ubuntu, debian, feroda,Mint,
redhat etc )
 Command line
 Raspberry Pi: Raspian (Debian-based)
 Pinet: Ubuntu server + Raspberry Pi
 Linux: robust, secure, easy to use, powerful

Features of Raspberry Pi 3
• CPU: Quad-core 64-bit ARM Cortex
A53 clocked at 1.2 GHz
• GPU: 400MHz Video Core IV
multimedia
• Memory: 1GB LPDDR2-900 SDRAM
(i.e. 900MHz)
• USB ports: 4
• Video outputs: HDMI, composite video
(PAL and NTSC) via 3.5 mm jack
• Network: 10/100Mbps Ethernet and
802.11n Wireless LAN
• Peripherals: 17 GPIO plus specific
functions, and HAT ID bus
• Bluetooth: 4.1
• Power source: 5 V via MicroUSB or
GPIO header
• Size: 85.60mm × 56.5mm
• Weight: 45g

Raspbian Booting Process
➢ Software's Required
• SD card formatter
• Python IDLE
• Raspbian-stretch 4GB file
• Windows Disk Imager
• Steps
• Connect SD card to PC & format SD card using formatter.
• Open Windows Disk Imager S/W & browse the Raspbian-stretch
image file.
• Write or Burn the Raspbian OS file into SD card . It will take few
minutes.
• After installation connect the mouse , Keyboard & monitor to
board.
• Then configure GPIO pins of board & do simple codes in python.

Python Programming
➢ Use Software‘s Python IDLE any version 2.7.8 onwards

Applications of Raspberry pi

POWER
5v micro
USB
connector
(Similar to the one on a lot of mobile
phones!)

3.5mm Audio
Standard
headphone
socketRCA Video
(works with
most older
TVs)
HDMI Audio & Video
(works with modern TVs and DVI
monitors)
A/V (Audio/Video)

GPIO
(Genera
l
Purpose
Input &
Output)
10/100Mb
Ethernet
2 x USB 2.0
ports
CONNECTIVITY

DSI
(display
interface)
SOC (System On a Chip)
Broadcom BCM2835 700Mhz
INTERNALS LAN
Controller
CSI
(camera
interface)

SD Card Slot
(supports SD cards up to 32GB)
Storage

CHALLENGES AND OPPORTUNITIES
 New operating system: linux
 Open-source, all almost tools/software are free
 Rich resources on the web due to its
popularity
 Resources link: www.raspberrypicamp.org
 Pi Educational Document (resources above
link)
 Pinet: Centralised user accounts and file
storage system for a Raspberry Pi classroom.
http://pinet.org.uk/

OPERATING SYSTEM
 Linux on a bootable SD card
 Fedora
 Debian
 ArchLinux

PROGRAMMING
By default, supporting Python as the
educational language.
 Any language which will compile for
ARMv6 can be used with the
Raspberry Pi, though; so you’re not
limited to using Python.
For primary age SCRATCH game
maker is bundled

SCRATCH
scratch is free from MIT .. thanks MIT !

PYTHON CODE

WHAT KIND OF PROJECTS ?
 Video DJ Mixer integrated Media player for
your TV to fight the rampant Lego Robot
Monster who is detected by your Home
monitoring webcam network which reports
also from the Weather Station that uses the
Car Super Bramble Computer to tell the
School Notice-board that the Solar powered
Wireless Rocket Widget should be sent back to
earth ...

TINKERING
GPIO pins if you’re after an
interesting electronics project.
 Gertboard - A GPIO expansion board from the
foundation for electronics projects
 USB Devices / Ethernet / Hubs / AV out
 Can be powered by 4 x AA batteries ...
