The Experimental Method

First of all, let’s download the application, point our smartphone, iPad, or cell phone at the flickering LED, and get the temperature reading. Give it a try, Little Rumi!

Gee, this is tricky. Wait, I’ve got it! Yay!

It takes a little practice to get the camera to recognize the signal. If the LED is too bright, the signal appears whitish, and the camera has difficulty recognizing it.

The signal is easier to read if you cover the LED with an acrylic smoked sheet; a transparent gray would be perfect. Ladies’ black stockings work especially well and are usually easy to find. Cut the stocking to cover the LED. Using a transparent battery cover keeps the stocking in place during the experiment.

OK. Let’s put our imagination to work to decide specifically what concept we want to focus on—what we actually want to make once we know we can get the temperature.

As a matter of fact, I was at the National Yunlin University of Science and Technology in Taiwan from June 13 to 15. I led an international workshop on making thermometers using Visible Light Communication. It was the world’s first workshop using this IT kit.
The workshop gained the interest of people from many countries and produced lots of interesting ideas. Each group was comprised of three people, and we all chattered away and had a great time. Art and design education focusing on light works beautifully in groups, as it sparks communication and leaves everyone excited, delighted, and exclaiming over the shared results. Let me show you some pictures demonstrating how the workshop unfolded.
