I've been working on a breadboard project in which 8 dip switches must be in the right combination in order to light an LED. But it simply refuses to work. I don't exactly know what is happening, so I can't explain the results. I have triple checked my logic in both my head and on simulation software, and I am confident my logic is correct. So the errors must either lie in my wiring or a faulty IC chip. *EDIT#1* Sorry, I'm really tired right now and accidentally just delete half my post while trying to edit it, so I will just try to diagram it.
