Hi there - first time poster and please excuse me if I couldn't find something on my own.
I would like to build a cable tester for 24 pin cables (although the number of pins doesn't really matter for my question I suppose.) My first instinct was just to source a 24 position rotary switch and swtich power to light up leds, but they're expensive and even if though two 12 postion switches would work I'm starting to daydream about something a little more slick. I'm hoping to just plug both ends of the cable into receptacles and instantly have 24 LEDs either light up or not. Of course if I just plugged in power, crossed wires would still light up an led and I wouldn't know I had a problem, so I'm thinking of something more like AND gates that would cycle through and latch an LED on if the pair of wires was good, and not if there was a problem. I'm just hoping for some sort of insight as to what components I would need, or if I should just procure an Arduino or something. I'm looking for an elegant and simple solution. Hoping to just go the way of old school ICs but also hoping to learn a thing or two.
Thanks in advance!
