I started to work with the idea of controling sound by sensors, so I build a circuit with Arduino using a potentiometer. The code in Arduino makes posible to change the frecuency when the resistor (the potentiometer) changes his value.

With the same code I can change the sensor by a photocell, and now the sound is modificated by the variation of light. Using a flashlight I produce a better demonstration of this variation.

The next step that I wanted was to be able to take these differences and printed on the screen using Processing. In order that, I modifyed a homework that I presented in the ICM class and I edited the code by one hand, making the value of the sensor be translated as the value of the size of the ellipses that the code draws. By other hand, making the sensor’s value can change the amplitude of movement of each “bug”.

Conclutions:

I made some mistakes when I got the sensor’s value and I added it to Processing code, so the transitions in the graphic are not continuous. This could be, because I took this number as an “int” and not as a “float” value. In this way I lost data accuracy so the graphic change drastically.

I think I could develop more this prototype in order to integrate better the visualization with the sound and the user interactivity.
