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.

To realize this goal, you’ll learn how a computer converts the changes in energy given off by our bodies (in the form of sound, light, motion, and other forms) into changing electronic signals that it can read and interpret. You’ll learn about the sensors that do this, and about simple computers called microcontrollers that read sensors and convert their output into data. In the other direction you will learn how to actual physical things in the world with devices like speakers, lights and motors. Finally, you’ll learn how microcontrollers communicate with other computers.

To learn this, you’ll watch people and build devices. You will spend a lot of time building circuits, soldering, writing programs, building structures to hold sensors and controls, and figuring out how best to make all of these things relate to a person’s body.
