Adding just a few conditions in a small program, and using Arduino integrated with sensors, we get to add intelligence to a BlackBerry Playbook application.

The Arduino board uses an IR range sensor to find targets. The IR sensor is placed on a servo to scan the area of interest (e.g. kitchen). The data is sent to the BlackBerry PlayBook tablet, on which we’ve built an application to present a sonar map and look for movement. If movement is detected, the application will sound an alarm and take a picture.
