i understand what active low means. the pin gets enabled when the logic is low (0) and so the pin works at logic (0). but my doubt is why do we need active low logic to set something to work. I mean if we want that pin to work why cant we just set it in such a way wer the pin works when it is high... wat difference does it actually make... either way we just want the pin to be enabled. why does it matter if we enable it with high or low logic... can someone pls explain...
