In this project, I will capture the electrical conductivity of the bacteria and other organisms for conveying the massage that there are many microorganisms everywhere around us. Then, I will send that input to Max/msp to generate a 3D/2D graphic of their electrical conductivity and project that graphic onto the wall, therefore the audiences can be participated.
This project is related to my DIY Bio project here.

The graphic style is inspired from an image of bacteria and other organisms under the microscope, mostly is dots and particles.
Arduino sketch : File:sensor_reading.ino
Max/msp patch: File:maxproject sirin 2019012901.maxpat
I followed the tutorial to create my prospective visual, but instead, my input is the electrical potentials from organisms.
This patch is using jit.gen and jit.matrix to generate a particle effect. The jit.gen is used for calculating force and mass to drive the particles, also the movement of them. In the tutorial, the equation that he used is F = m*a and the particles will move in a vector quantity, in this case, to the center.
As a result, the particles are moving to the center when there is a change from electricity potentials, when the input doesn't change, the particles will arrange in circle. The visual is inspired from the image of the organism that I cultivated inside the petri dish.
After testing on the organism's electric potentials, I noticed a tiny difference in the result in every organism. I will use that input to shift the visual which are, in this case, color and shape to represent their appearances in a experimental way, so I set the three conditions to differentiate them. However, the particles' movement will remain the same in every input.
This implementation allows many participants to be engaged in the installation at the same time. There are many possible ways to interact with it, for instance in this sample scenario, one person is changing the input while another is playing with the visuals and guessing which organism is it.
In conclusion, there are many possibilities of this project, for instance, to cultivate more various organisms which also have different electric potentials to generate other visual styles.
