Minecraft Logic Gates! Slide2

Logic Gates

Learn what a logic gate is and what they are for.

Be able to identify common logic gates.

Understand how truth tables work.Slide3

What is a logic gate?

Logic gates are part of the circuits inside your computer. They can take several INPUTS.

Depending on the type of logic gate used these inputs are then compared against each other, and a single OUTPUT provided.

Four types:

AND

OR

XOR

NOTSlide4

How does it work?

As we already know, our computers can only understand electrical signals that are ON and OFF (or 1 and 0!)

A logic gate looks to see which inputs are on and then based on what type of logic gate it is, produces and either on or off output.

What is it called when we use a two number system?

What is it called when we use a ten number system?Slide5

AND

An

AND

gate requires both the inputs to be on (1)

OR

An

OR

gate requires at least ONE input to be on (1).

It also works if both inputs are on!

XOR

An

XOR

gate is an EXCLUSIVE OR gate - it requires ONE input to be on (1) exclusively so

it will NOT work if BOTH inputs are on!

gate has just ONE input and the output is always the opposite of this input

What inputs does an AND gate require to produce an output that is ON?

______________________________________________Slide11

What inputs does an OR gate require to produce an output that is ON?

What inputs does an XOR gate require to produce an output that is ON?

What inputs does a NOT gate require to produce an output that is ON?

You mentioned Minecraft?

So in Minecraft we can use something called redstone to create electrical circuits as the redstone dust conducts energy just like an electrical wire!

This means we can use redstone to build logic gates to build different mechanisms! Slide15

Log in to the “Logic Gate Learning Center” world on Minecraft: Education Edition.

Take a look at the simple gates in the spawn area.

Go and play with the ready built examples - read the signs!

Find yourself one of the build areas (beginner Minecrafters work in pairs!) - if you ask your teacher nicely they may even put your name on the sign.

Build anything you want - but it must have at least ONE logic gate to make it work!

Ideas are:

A working shower

A lighting system

A working kitchen sink

A railroad and cart

A roller coaster (it will have to be tall rather than wide!!)

Challenge:Slide20

Quick Quiz:

Name three different types of logic gate:

__________ b.

__________

c.

_________

An OR gate requires BOTH inputs to be on to produce an OFF output.

TRUE / FALSE

An AND gate inverts the input signal. TRUE / FALSE

A NOT gate is always on?

TRUE / FALSE

An XOR gate requires only ONE input to be ON to produce an ON output. TRUE / FALSE

These online games can help you remember your logic gates!
