Project 2: Build a Better Button

Learning Goals for the Project

  • Learn about Circuit design
  • Learn how to communicate between an Arduino and your phone
  • Apply your knowledge of physical design (3D printing/laser cutting) to support your goals
  • Build a simple circuit that is enhanced by its connection to your phone

Basic Requirements for Project

Your project should demonstrate your ability to take input from at least one button (or other sensor), capture that information by phone, and do something with it. For example, you could build a door opening sensor (using a button or proximity sensor) that causes your phone to announce the door was opened, or a single switch control for scrolling or tabbing through a web page, or a capacitive sensor that captures a log of how often a cane is used.

You should make a case for why this is an assistive technology of some sort.

Resources that might be helpful

There is some great software that con be connected to the arduino including 1Shield, AppInventor, and Blynk. Some work only for Android, others for both Android and iPhone.

There are lots of really great examples online of arduino based projects, arduino projects that involve smartphones, and arduino projects that involve 3D printing or laser cutting. Many of them are too complex for the expectations of this project, though they might help to inspire final projects, or give you ideas for something simple you can do in a week. Here is a sample:

Hand In

Create a Thingiverse page for your project with a brief description of the project, a video, any 3D printed files, and a schematic for your circuit. Turn the URL in by email with the subject: Project 2.
