There are more logic gates out there. This guide is made for those who want to understand and create more complex Logic Gates and Flip-Flops

Contents:

  • Nor
  • Nand
  • Xnor
  • SR Latch
  • T Flip-Flop
  • D Flip-Flip
  • JK Flip-Flop

Let us start.

1) Nor

  • This gives a signal as long as not one of the signals is on
  • This works in exact opposite of how an Or Gate works
  • It gives a signal when this signal is not on nor is the other one

On when Both signals are off

Off when one is On

And still Off when both are On

OK got it?

2) Nand

  • It gives a signal as long as both the inputs are not on
  • Works in the opposite way than a And gate
  • It gives a signal as long as this signal AND that signal is NOT on.

On when both are off

Still on when one is on

but off when both are on

3) Xnor

  • It will give a signal when both signal are at the same state
  • Works in the other way than on how a Xor works
  • Think of this as a Xand Gate. It will give a signal as long as both are on or both are off

On when both are off

Off when one is on

And on when both are On

Let us go to the Latches and Flip-Flops

1)SR Latch

You may think. We already have an SR latch.
Yes but they don't work exactly the same as this one.
This SR Latch has two outputs.
These one output for the set and another for the reset

Here are some diagrams from wikipedia.
I am not lazy to make one myself but I feel that you guys need to see the whole thing in entirety

The SR Nor Latch

The SR Nand Latch

And the Gated SR Latch

I will explain the Gated SR latch though.
I like this one because it followed the old SR Latch pattern.
Where all you need is a signal in order to allow a signal to go through.

All of these function just like a regular SR Latch except that they provide an extra output

2) T Flip-Flop

  • Every time a signal is made, it will switch outputs

Here is my T flip-Flop

And when I press the button again, the output is switched

And remember, the top-left and the bottom right should be connected as well as the top-right and the bottom left. Kinda bit like a crisscross. As shown here

I will probably update this topic once I understand the other flip-flops well enough.
But for now, these gates and flip-flops will do.

Thank you. Theoretically, You can make a Lights Out puzzle with that.
I tried to make one but too many design revisions and technical problems caused me to delete the world and create one called Stress Relief to release my anger. :P
Although there are many uses for the T-flipflop. I have not tested my ideas for it yet though.

Is there any chance that you will upload your world(s) so we can interact with them? (For the people who are either to lazy(me) or people who don't understand how to build them)

Sure. Just wait a while cause I deleted the world where I build all my machinery due to technical problems with my device.

OK that is. An SR Latch. Honestly, I cannot say that it is an SR Nor or SR Nand since it is made from SR latches.
Let just call it An SR latch. Yes that is a SR Latch. That works too. 
Looks like we Found some SR Latchception.

Little tip. Do your gates on walls, and your wiring in Wire Through blocks. This way, you can have wires nearby without connecting. If you try to use just plain wires, you will have to space them out all over to prevent them from connecting. So when just trying to transport some signals to different gate workspaces, use wire through blocks.

JK Flip-Flop added, just look at our wiki!! Link here - http://survivalcraftgame.wikia.com/wiki/Full_logic_gates_guide (there are listed all logic gates, JK flip-flop is at the bottom)
