fco: a musical assistive technology device that allows people with limited movements to beget multiple sound possibilities with one pressure sensor!Besides telling the account of the project I wanted that people who went to this event could go inside it, and understand in an interactive way the fundamental concepts of the science and technology behind this project.
The concepts were:
frequencies
the idea of using a sensor to control something else
what is programming?
And these are the Bits I took with me and how I used them

JPG1200x800 828 KB For explaining frequencies I used an oscillator. As pictured above, or I would start with a bargraph and glide the oscillator knob until the change of frequency was unperceptive to the eyes. Then I would snap the speaker after the bargraph to explain that we could not only see the frequencies,but hear them. One of the most sharp reflections that we got from this circuit was that "sound starts to rupture" (as one guy observed) when our eyes start to differentiate the change of frequencies.
final but not least, I had another surprise, and was that blue plastic thing with INNOVAR branding.

JPG1200x800 920 KB People thought that this was there because it was a prize or something like that,but the truth was that this object was fundamental to beget "magic" with the bargraph. As I establish this blue filter over the bargraph, red and orange lights would disappear, and leaving the green ones intact. All this WOW performance was there to reflect that frequencies even play a role in the colors of light.
For the part of using a sensor to control something else,I suggested trying the pressure sensor alone with a bargraph and then see how this sensor affected the circuit with the oscillator + speaker. I preferred understanding the use of the pressure sensor with the bargraph because I reflect is more natural to perceive the change with it and because of the idea I wanted to present next: "what is programming?"
I would say something like: we can understand the change of pressure on the sensor as a change in the number of lights on, but we can also measure it as a number (and there I would snap the number module). And I remarked that this was important because this was the format in which programming works and can understand the things that happen in our physical world. Also, or I would explain why I decided to use programming in this project,and how writing something in my computer could change the behavior of the instrument.
Of course, my speech was not always the same (neither the order of concepts), and if anyone had a question,I would encourage him/her to try it and see what happened.
Happily, my stand had many beautiful chaotic moments like this one

and also some kids had plenty of time to explore their own circuit combinations and sounds [/images/emoji/apple/smile.png?v=0]
