Joo Youn Paek’s Zipper Orchestra (2006)

This is a musical installation that lets you control video and music using zippers. The zippers are wired to a microcontroller using conductive thread, and the microcontroller communicates serially with a multimedia computer that drives the playback of the zipper movies and sounds as you zip.

The most basic network is a one-to-one connection between two objects. This chapter covers the details of two-way communication, beginning with the characteristics that have to be agreed upon in advance. You’ll learn about some of the logistical elements of network communications: data protocols, flow control, and addressing. You’ll practice all of this by building two examples using one-to-one serial communication between a microcontroller and a personal computer. You’ll also learn about modem communications and how you can replace the cable connecting the two with Bluetooth radios.
