Hey, I want to use my Teensy 4.0 to read bioelectric signals from a mushroom or plant.
For this I want to use two subdermal electrodes (which penetrate the mushroom/plant) to measure difference in electric potential (voltage). Extremely low voltage is expected (around 0.03 to 2.1 mV [source: https://royalsocietypublishing.org/doi/10.1098/rsos.211926]) and I was wondering how I could go about reading this? Do I need anything else besides the Teensy board with its built in ADC? For starters I would plug both electrodes into analog pins 0 and 1, use the analogRead function and then substract both values?
