3. A Fast Increasing Number of Smart Things…
A very large ecosystem of smart things,
complex application development

4. EVRYTHNG: A Facebook for Things
Think of a Facebook for things − individual things with unique
digital profiles, like we have, to update, share and add to…
Applications

5. Arduino: Fueling IoT Prototypes
• Leading open-source
electronics prototyping
platform
• Features:
• Various sizes, lots of available
shields, low cost (from 20$ to
70$)
• Processing-based Java IDE
• Eclipse + Netbeans plugins
[http://www.robotshop.com/]
• ATmega-based (8-16 Mhz)
• Alternatives:
• Open-picus (Flyport)
• SunSpots, etc.

6. Android Phone Home
• Mobile phones as
bootloaders of the IoT
• Openness at the core of
Android (Android @
home)
• Arduino support through
two projects:
• Android Open Accessory
Development Kit (ADK)
• Android Debug Bridge (ADB),
microbridge project

7. Android Talking Arduino: ADK
• Official accessory
prototyping platform
• ADK support in:
• Android: 2.3.4+ (kernel 2.6.35)
[http://tellart.com/]
• Android tablets: 3.1+
• Arduino: Mega ADK
• + official way
+ turn project into real
accessory
• - cost of ADK compatible
hardware (phone + Arduino)
- complexity

8. Android Talking Arduino: ADB
• « missuse » of the
Android debug system
• Several Arduino shields
• USB Host Shield 2.0
circuits@home
• Microbridge: open-source
Arduino + Java library
• + low cost
+ works with many Arduinos
[http://www.circuitsathome.com]
+ works with Android 1.5+
+ also ADK compatible
• - lack of support
- only for hobby prototypes

• ADB-based project:
• USB Host Shield 2.0
• Arduino Uno
• Sensing:
• LF: Cable + resistor
• HF: LT5534 RF Power
Detector
• Features:
• Real-time monitor, logger
• Educational tool
