Is it possible to use the threshold bit in the reverse sense? Reading about it (I don't have one yet) I understand that the threshold bit triggers when the signal goes above a certain limit. But what if I want to trigger it when the signal goes below a certain limit?
Will inserting an inverter between the signal and the threshold work? Or is the inverter purely digital (ie. only has 0v or 5v value and nothing in between, or does it actually reverse the voltage coming in).
