Hey,
I´m trying to combine capacitive sensing on three cupper surfaces while measuring resistance between these.
I´m using trill craft, hooked up to an arduino uno as described in the bela tutorial.
Unfortunatley I´m not an electrician and dont understand how measuring capacitance and resistance interfere with each other in this circuit.
in this screenshot one can see my setup. when i connect foil1 and foil2 the capSense value get stuck at ca. 3500.
why is that?
is there a way to measure the resistance between the two foils which are attached to trill craft?
could it be that what happens is a kind of feedback?
I read that capSens works by transmitting a pulse which is then delayed by the capacitor (i.e the touch sensor). the capacitive sensor value results from calculating the delay between the send and received pulse- is that correct? is this how the trill craft capSense works?
