GMU:DIY Bio: doing things with biology/Sirin Unmanee/16.01.2019 : Electric Potentials

I attempted to capture the electric potentials from the organism that I'm cultivating, using the Arduino. My aim is to differentiate the number from each organism and find a possibility to use that number to create different visuals.
(reference : Martin Howse, Radio Mycelium [1] )

At the beginning, I captured the electric potentials from my hands to settle down a control parameter, the number is around 830-860, but mostly is around 840.

Then, I tried with three different organism which are bacteria, bread's mold and Kombucha's mold.

1. Bacteria

2. Bread's mold

3. Kombucha's mold
