I am relatively new to electrical work, mostly stay on the software side of things. I recently soldered header pins onto a few led matrixes I have. They are 3 wire leds (power, data, ground). I'm trying to figure out if I shorted the connections when I soldered them before I plug them in (I see tiny gaps, but first time soldering a breadboard and easy to use too much!)
I have continuity through everything I should have continuity through - data to data, hot to hot, ground to ground, but I also have continuity from hot to ground.
Part of me things that makes sense since it should be a circuit, part of me thinks that it means I have hot and ground touching in the soldering somewhere.
