Hello,
I'd like your expert advice on how to have a "negative voltage" trigger something. Example will be: a circuit that will be triggered by -5v but not by +5v.
I'm looking for a simple and cheap way to achieve this without use of a rectifier or a microprocessor.
Is there a simple and cheap logic gate or comparator or anything this newbie is unaware of that will do this?
Thank you for your time for this newbie.
