Simple Logic Gates –Minecraft Computer (Part 3)

12 Jul

Welcome to step 3 of “How to Build a Computer in Minecraft” Our last post explained Binary Code and how this code can be created using Redstone. In this post we will display simple constructs built in Minecraft called Logic Gates. These gates are made of Redstone circuits and combined with any of the following:

Simple Logic

Here is a key for the following diagrams. In our next post we will get deeper into other types of Logic Gates and advanced uses, but for today, let’s stick to these simple logic gates. Once you can build all seven of these gates you are well on your way to understanding how to build and operate a Minecraft Computer.

Not Gate

Also known as an inverter, the NOT Gate is used when you want the opposite output from the input you give.

AND Gate

An AND Gate is used with two or more switches or inputs. The output is “ON” only when both inputs are “ON”

NAND Gate

A NAND Gate is the opposite of an AND Gate and also has two inputs. The output is toggled to “OFF” only when both inputs are toggled to “ON”.

OR Gate

An OR Gate uses two or more inputs. Whenever the switch is toggled to “ON” the output is toggled to “ON”. The only time the output is “OFF” is when both inputs are “OFF”.

NOR Gate

A NOR Gate is the opposite of an OR Gate. Whenever at least one switch is toggled to “ON”, the output is toggled to “OFF”.

XOR Gate

An XOR Gate uses two inputs. In this gate, the output is toggled to “ON” when one switch is “ON” and one switch is “OFF”. If both switches are “ON” or “OFF” then the output is toggled to “OFF”.

XNOR Gate

An XNOR Gate is the opposite of an XOR Gate. It uses two inputs. When both inputs are either “ON” or “OFF” the output is toggled to “ON”. Otherwise, the output is toggled to “OFF”.

Here is a video version of the logic gates shown above. It is a straightforward look at Logic Gates with some very cool music! Thanks to the YouTube User Chaaozz for this simple video.

In our next post, we will continue to explore the many uses of Logic Gates in Minecraft, how to incorporate them into a computer, and share some of the cool stuff we have built. Stay tuned and make sure to check out Clipboard+ on Kickstarter! Only 5 Days left to Change the Way You Work.
