14. • Home Automation Platform based on Java EE and
do it yourself hardware / gadgets
• Allows you to integrate your house with social
networks like Twitter
• Different usage of Java EE and Glassfish
• Java Enterprise Edition Embedded comes a reality
with Java Enterprise Suite!

15. Things-API.org
Home Automation project evolution with more
abstract approach: Things Automation !?!
Internet of Things API / Things Automation API:
Provides a simple, uniform and easy to use API to read
sensors and control things;
Java SE, Java EE, Java ME, JavaFX = SAME API!
Things-API is the "JDBC" for Internet of Things
Communication Independent: IP, Serial, Bluetooth,
ZigBee, I2C, USB, etc.

18. Robots & Internet of Things
Robot = sensor, actuator and processing
IoT = sensor, actuator, processing + …
communication
integration
interoperation
security
massive update (even changing firmwares and
drivers)

27. Raspberry PI vs Arduino
• Arduino is the baby steps to embedded and limited
microcontroller programming;
• Raspberry PI is the baby step for ARM
microcontroller programming;
• Arduinos (or Atmegas) are very useful as a
dedicated actuator / sensor control / driver;
• Raspberry PI will provide powerful processing,
security, integration, full TCP/IP and so on..
• Prototyping platform + TCP/IP = EXPENSIVE!

28. Raspberry PI + Arduino: how?
Serial RXTX
Easy and simple
Sync issues
Limited speedy
I2C: our next step using Device Access API
SPI: for faster communication

29. Things-API.org
The project Things-API.org
@vsenger
@yarasenger
Globalcode – Open4education

30. Things-API.org
Things-API
Simple abstraction:
Device: the thing
Component: some part of the thing
Component = Input / Output:
Input = Sensor : light, temperature, accelerometer, gyro, etc..;
Output = Actuator : motor, led, relay, buzzer;
Sensors = read
Actuator = write
