Hi , I'm looking for a simple method of checking for a resistance at the end of a cable run based on the comparison to a given similar resistance. I need the comparison to have a tolerance of e.g. 5-10% to allow for cable length and the initial tolerance variability of the component..
Im guessing this somewhat ressembles a wheatstone bridge however I'm looking for an LED to be illuminated either in no match or in match whichever is easier.
Does anyone have any ideas.
