Assignment 6: Networked Wearable

« Previous: Assignment 5: Nonwoven Next: Assignment 7: Final Project Proposal »


For this assignment you will work in teams, in collaboration with the 21W.789 Communicating with Mobile Technology class, to build a textile that talks to a mobile phone. With your team you should create a webpage that documents your project. Your page should include pictures and a discussion of your experience. Also create a short video of your project in action; post the video online (Vimeo, YouTube, or your own site) and include a link to your video in your documentation page.

Make a Textile Arduino

Drawing of a circular piece of fabric with an ATMega168 microcontroller IC in the center. Many leads connect to labeled conductive regions on the fabric, and several regions include other electronic components.

An example textile Arduino circuit.

Here's a diagram that shows how the ATMega168 pins are mapped to Arduino pins:
