I've seen at least 5 topics about it, so i want to say - it's intended to start with only NAND, cuz it's the most basic gate that can be used to create all the others (nand is turing complete)

You don't know how? Ok, i will explain:

NOT - AnandA (fork IN into both nand inputs)

AND - not(AnandB) (double negation)

If you used v1 it's all you need, but for newbies:

OR - notA nand notB (google De Morgan's law)

XOR - A or B but(and) not A and B

NOR/XNOR add NOT

And i hope that's all you need to know, if no, ask here
