Week 7 Homework: #

Switch && Feedback #

Switch #

Watch the videos on your Arduino kit, Electricity and Circuits, setting up the Arduino, and making a basic switch read these notes from Sparkfun on how electricity works, then:

Build a circuit with a switch you make on your own that can be operated without using your hands. Think about what you have that is conductive. Aluminum foil, copper tape, and/or jumper wires work well. Be careful you do not cause a short! Always unplug your Arduino before changing anything in your circuit, and check to make sure there are no loose wires.

Feedback #

With the switch you built (or a different one if you want to experiment) use the Arduino to provide some meaningful feedback on what the action you engage in means. For example — if you are trying to notify someone that their posture is good or bad, could you make a switch that was based on how they stood, and notify them if they are not straight? What about getting someone to smile for a camera? Using the digital input and output provide feedback to your user that is meaningful in context. Labeling LEDs with text, or using different colored lights to indicate things is helpful, try diffusing the light with paper or a ping pong ball, how does that change the quality of the light?

Reading #

• Read/Watch the tutorials on setting up the Arduino IDE, what all those pins on your board do, and digital input / digital output
• Read this article from Don Norman, Attractive Things Work Better.
• Optional: Physical Computing by Dan O'Sullivan and Tom Igoe
