Lights! Speed! Action! Fundamentals of Physical Computing for Programmers

The definition of “computer graphics” as used by artists in new media and kinetic areas of the arts is much more expansive than simply rendering to a screen. A visit to the SIGGRAPH 2013 Art Gallery, for example, reveals a wide variety of uses of physical computing, embedded control, sensors, and actuators in the service of art. This course is for programmers, educators, artists, and others who would like to learn the basic skills necessary to include physical components in their computing systems.

The course is targeted at programmers with little or no electronics background. It begins with basic electronics concepts as they are used with physical computing components, then reviews a variety of sensors that provide information about the physical environment (light, motion, distance from objects, flex, temperature, etc.), programmer-controlled lights (LEDs), and programmer-controlled motion (servos, motors). The use of these components is described in the context of the Arduino microcontroller, but the topics are general and will transfer to a variety of other computing platforms. Although the course includes a few simple formulas, the strong focus will be on practical usage and common-sense applications in real circuits.
