Why Won't My LED Light Up? Troubleshooting a Combination Light Circuit

    Combination Light
Click For Summary
The user is troubleshooting an LED that won't light up in a breadboard project requiring a specific combination of 8 dip switches. They have verified their logic through simulations and believe the issue lies in either wiring or a faulty IC chip. Frustration has led to accidental deletion of part of their post, and they plan to take a break from the project to clear their mind. They may share a diagram or picture of the circuit later if they continue to struggle. The discussion reflects the challenges of debugging electronic circuits and the emotional toll it can take.

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.

I'm quite frustrated right now. I almost finished making my diagram, all to get an error and have the diagram deleted. So I really just don't care right now. I'm sure I'm just making some stupid mistake that I just need to calm down and think logically about for a day, so I will not be posting any more on this thread.

If I get too annoyed with my circuit in a couple days I may just post a picture of it.

My apologies for the waste of a thread.
 

Thread 'Electric power distribution from powerplant to homes'

I am trying to understand how transferring electric from the powerplant to my house is more effective using high voltage. The suggested explanation that the current is equal to the power supply divided by the voltage, and hence higher voltage leads to lower current and as a result to a lower power loss on the conductives is very confusing me. I know that the current is determined by the voltage and the resistance, and not by a power capability - which defines a limit to the allowable...
