Sorry if this is the wrong forum, I'm really bad at judging that. I've just started to get into electronics and am already confused. How do comparators work (in layman terms)? Doesn't it just compare whether pin 2 or 3 (I have LM393) is getting more electricity, and then turn on pin 1 is pin 2 is more? Thats how I understood it, but when I tried connecting two different ohm resistors (which should create differences, right?) nothing interesting happened to the LED I had in the circuit. If it was already on (which happens if the negative end is the side connected, which I also don't understand why thats the only way it works) it stays on, and if it was off (positive side) it stays off. The ONLY way I can get the comparator seem to be able to have any affect is if I connect a wire from pin 2 to negative power, which turns the LED off, which I also don't understand. Can someone please help me understand what I'm doing wrong? I've tried every wire combo I can think of.
