3. WHAT IS THE RASPBERRY PI
• “the $35 dollar computer”
• Well, here is what you also need:
• $7 Power supply
• $12 SD card
• $10 Wifi dongle
• And might also opt for:
• $15 USB SD card reader
• $15 USB Ethernet adapter
• Consider buying 2 of everything!
4. WHY THE NAME RASPBERRY PI?
• From the UK aimed at generating
excitement in computing with kids
• Raspberry comes from a tradition of fruit
named companies:
• Tangerine Computing Systems, Apricot
Computers, Acorn, BlackBerry, Cherry
Corp, Papaya Studios, Apple
Computer,…
• PI was originally planned to have a built-in
interpreter for python language
• Acronym for Python Interpreter

5. RASPBERRY PI HISTORY
Feb: Pi2 A7 processor, 1 GB RAM
Apr: Windows 10 for Raspberry Pi
Nov: Pi Zero, lower power, cheap
2012201320142015
Jul: Model B+, more GPIO, USB, micro SD
Nov: Model A+ more GPIO, micro SD
Feb: Model A, no Ethernet, cheaper
Oct: Model B with 512 MB RAM
7. RASPBERRY PI AND SENSORS
• Unlike Arduino and other microcontrollers, Pi runs
at 3.3v
• Sensors are generally categorized as either
analog or digital
• Pi only supports digital sensors, but analog to
digital (”A to C”, or ADC) hardware is available
• Two values for a pin:
• High == 3.3v (>2v)
• Low == 0v
8. RASPBERRY PI – THINGS TO CONSIDER
• Lots of prior work with Pi, Arduino, Spark/Particle
Core/Photon, BeagleBone, Edison, PICAXE, …
• Consider voltage level of board
• Consider if sensors are reading analog or
digital data
• We are just getting started with Windows 10 on
the Pi
• Be patient and be willing to reflash SD
• Give back to the community, publish your
findings
• There are some GPIO pin differences…
11. WINDOWS 10 IOT CORE
• Version of Windows 10 that is optimized for
smaller devices
• With or without a display
• Runs on the Raspberry Pi 2, Arrow DragonBoard
410c & MinnowBoard MAX
• Utilizes Universal Windows Platform (UWP) API
for building solutions
15. Breaking down IoT…
That data
needs a place
to live…
We connect it to the cloud
and manage the data.
16. Breaking down IoT…
so you (or a machine)
can make smarter
decisions.
We uncover actionable
insights
17. COMMON IOT SCENARIOS
Connect and learn
about things
Monitor things that
are connected
Search for things
Manage things
Play with things
