Start from ArduinoBlinkLED here:
GitHub - Lauszus/ArduinoBlinkLED: Source code to use with: https://github.com/felis/USB_Host_Shield_2.0/blob/master/examples/adk/ArduinoBlinkLED/ArduinoBlinkLED.ino What hardware for communication you are intent to integrate?

i can help you with some basic things for home automation.

Arduino BLUETOOTH Communication with PC :- Embedded Systems: bluetooth

arduino relay interfacing (to connect fan or bulb):- Embedded Systems: relay

If you are plannig to use an Arduino Ethernet (either the official or cheap ENC28J60 shield) you can try this app

that works with this code on the Arduino
http://code.google.com/p/souliss/

Is a library, just load the first example on your Arduino (you should have some care for the configuration file) and all things will work automatically.

Regards,
Dario.
