Week 4 Assignment

(1) Choose one variable to test (distance, surface area, conductive material, substrate, etc) and make three sensors to test that variable. Make a hypothesis about each test BEFORE you construct the sensor then document your result.
For example, my variable is surface area. I will make three sensors out of papper, copper tape, and velostat, but I will change the surface area of the copper tape in each sensor. I hypothesize that the more surface area for copper tape…. (complete your own thought :))

> Be sure to answer the following questions in your documentation:
> What conductive materials are used? What non-conductive materials are used?
> How much of each material is used?
> What state changes occurred in the LED if any?
> What is the resistance of the conductive material?

(2) Make sure you bring your Arduino Uno and a breadboard to the next class. You can also bring a Lilypad, Flora, Mini, etc in addition to the Arduino Uno.

(3) You are *highly* encouraged to go to Maker Faire.

(4) Watch Masimo Banzi’s TED talk

(5) Learn a New Craft Project DUE NEXT CLASS
