I leave a new App Note that describes how to implement a presence simulator controlled from the Cloud (using an Arduino Ethernet and the NearBus connector). The system consists in a combination of different internet free services as Twitter and IFTTT (www.ifttt.com
An Arduino Ethernet board is used to control a power switch to turn on and turn off a light. This design is intended to show you how the NearBus Connector simplifies the way in which these kind of Internet-based projects can be implemented.
As showed in the picture the system consists of an Internet configurable clock (from IFTTT) that sends ON / OFF messages through Twitter to the NearBus connector. The NearBus connector forwards these messages to the Arduino Ethernet board (through Internet) who Turns On and Turns Off a power switch allowing in this way to control the light sequence form any place with a simple browser.
I leave the link to the project (step by step) if anyone is interested in implementing it.http://www.nearbus.net/presence_sim.html
