The document discusses using Arduino boards with Android devices through the Android Open Accessory Development Kit (ADK). It describes typical applications that combine the capabilities of Android phones and Arduino boards, such as lighting control, wireless sensors, and car monitoring. It provides an overview of how the ADK software libraries allow Android and Arduino boards to communicate over USB or wireless connections. Examples of specific projects are presented, including an orb display, soil probe, and car/bike monitors. Code examples and references are listed for exploring Android and Arduino development further.

1. OSHCamp 2012

2. Why ADK?
Google want peripheral manufacturers to create
interesting stuff
Android hardware can't do everything
Arduino can do a lot that a phone can't
Together they're a powerful combination
And mostly Open Source!

3. Typical Apps
● Wall Clock ● Lighting Control
● Car/ Bike Monitor ● Wireless Orb
● Body Monitor ● Door Monitor
● Multimeter ● Terminal
● Logic Analyser ● AV Controller
● 'Scope ● Door Key
List of sensors and actuators

4. How it works
● Android
● Cable/ USB
● Arduino w. USB host
(multiple options)
● Software libraries
(from google code)

5. How it works (2)
Android Arduino
● Open UDP socket ● Open UDP socket
● Listen for messages ● Listen for messages
● Send messages ● Send messages
● Dialogue w. server ● Handle sensors
● Handle sensors ● Handle actuators
Concurrent execution of multiple threads

6. ADK 2011 vs. 2012
2011 2012
● Mega 2560 AVR ● ARM processor
● Standard shield(s) ● Clock shield combo

7. Software
Android Arduino
● Program in Java w. ● Program in C++ w.
Eclipse Arduino IDE
● Examples available ● Examples available
● Processing a ● There's an Arduino-
restricted option style IDE for the 2012
(ARM) as well

8. Alternatives
IOIO Amarino
● Cheaper w. limitations ● Cheaper w. limitations
Anyone want to explore these?

9. Apps Experience
As an output device As an input device

10. Orb(s)
●
1st version was MBED
hack
nd
●
2 a Nanode version
(memory issues)
●
3rd version using ADK
(at OTA2011)
● Cosm as intermediary

11. Soil Probe
● Mapping moisture
patterns: sensors in
contact + geolocation
● Built this at OTA2012
● Air + soil
● Temp. + humidity
● Linked to “JatRobot”
project - “Let's disrupt
the farming business”

12. Car Monitor
● Started to make this
using OBDII
● Large number of
measurements from
most cars
● Shame mine not
included :-(
● Alternative of
CANBUS

13. Bike Monitor
● Commercial products
out there.
● Potential for adding
sensors etc
● London cyclists want
this with cheap and
accurate pollution
measurement !?

14. Code
● ADK 2011 package download (zip)
● Also check board suppliers sites for examples
● e.g. Seeed Studio wiki
● IOIO from the main man
● Amarino docs/ code

15. Sunday Session
● Anyone want to hack this stuff?
● ADK 2011 (1)
● Sorry no 2012 (yet)
● IOIO (1)
● Amarino (1)
