Is the use of optoisolators to isolate and clean a signal before an OR gate input good practice? If not what is better?
If you’re creating an alarm system for an industrial customer, you should look into a concept called Fully Supervised Loop. FSL systems use switch and end-of-line terminators to detect whether a loop ...

I can see several possible problems.
Pin 1 (A1) is connected to the lower positive bus, but I don't see any other connection to that bus, unless you've connected it at the end that we can't see in the ...

I am trying to implement a function using only NAND gates
The reason NAND gates are often considered the "most basic" building blocks are that:
They (and NOR) are the least costly in silicon. Four transistors form the core.
The output is more ...
