Erin RobotGrrl discusses using apps to interact with Arduino projects. Apps for Arduino provides a simple framework that allows Arduino hardware to work with computers and iOS devices through software. The apps are open source and action-based rather than pin-based. RobotGrrl also describes her educational robotic pet project called RoboBrrd, which uses lasercut parts, an Arduino brain board, and interactive software to teach programming and electrical concepts to students ages 10-16.
