A talk about Arduino given at Macquarie University on May 22nd, 2009

1. Arduino & Physical Computing Steve Cassidy James Howarth Matt Cabanag

3. Arduino

4. Programming

5. Sensors

6. Show and Tell

7. Physical Computing Physical Computing is an approach to learning how humans communicate through computers that starts by considering how humans express themselves physically. In this course, we take the human body as a given, and attempt to design computing applications within the limits of its expression. http://itp.nyu.edu/physcomp/ (ITP is a two-year graduate program located in the Tisch School of the Arts)
