Hey guys, Surfboy20 here today.

We're back for a new video,

which is redstone circuit tips 
for you guys.

So, in case you are not 
quite the redstone master,

here are a few circuits that will help you
get started in redstone.

So over here on the far right,

we have these logic gates,

and I will explain these 
in further detail later.

Over here, we have the pulse modifiers.

And over here, we have 
the redstone clocks.

So, now let's get into
each individual one,

and I'll show you how to build them
and how they work.

So let's get started with the clocks.

This clock is just a simple,
quick repeater clock.

It's nothing fancy, it's been
in the game since repeaters were out,

and here's how you build it:
you place one repeater down right there,

and you place another repeater
down right there,

facing opposite from each other.

Then you place redstone dust here,
here, here, and here,

and a redstone torch
and break it really quickly right here.

So that creates the clock. Simple.

Now what this can be used for

is launching multiple 
items out of dispensers

or stuff like that.

Now over here, this is a comparator clock.

Comparator clocks are really simple

and the fastest clock 
you can build in Minecraft.

So this one's quite self-explanatory,
but I'll show you how to make it.

So right here you have your comparator.

Make sure to set it on subtract mode.

And then you can do that 
by right-clicking.

And then you place redstone 
here, here, and here, and that's it.

You can power it using either 
a redstone block or a torch or a lever,

anything like that, and it'll start
making a quick pulse just like that one,

just a little bit faster.

Now over here, this is a really,
really simple one.

This is a hopper clock.

Now, a hopper clock just uses an item

flowing between two hoppers 
facing into each other

and you take a comparator output of it,

and that will give you 
a really long clock.

So let's go ahead 
and grab one of these hoppers.

Place one down here,
and in order to place a hopper

on another hopper,

hold down shift and right-click,

and it'll place that hopper 
facing into this one.

Go ahead and break this one,

and shift, right-click on that one
so now they're facing into each other.

Then take your comparator and set it 
on the floor right in front of it.

And that will be where
your output comes out.

You can put this on
this side, this side, this side,

this side, this side, or this side.

Any side that has a hopper.

So now you need to take one item
and place it in one of the hoppers

and it'll start your clock.

So those are the redstone clocks
I have prepared for you today.

Now let's take a look 
at some of the pulse modifiers.

Okay, right here, this is 
a pulse modifier number one.

This is a pulse extender.

So what a pulse extender does
is when you hit a button,

it extends the pulse 
past when the button stop's pushed.

So, as you can see,
the pulse just gave out right there,

but the button has been unpressed 
for a long time.

So these can be super useful
for hooking it up to clocks,

making clocks run longer,
and other cool stuff,

like keeping a door open for longer.

And it's really simple,

all these circuits I've made really simple
so it's easy to build.

So right here, 
you can place one comparator,

and the other one 
facing in the other direction,

and redstone, redstone, redstone,

with a block, and then a button.

So, as you can see,

it perfectly extends the signal 
just like this one.

So now let's move on 
to the pulse shortener.

Now this one is really cool because,

as you can see,
watch this redstone dust,

it'll give a really quick pulse,

almost not clearly seen,
but it really does.

So now I'm gonna show you 
how to build this one.

Now this one's a little bit more tricky
because it has a piston,

so you're gonna need iron and slime
'cause it's a sticky piston.

So let's go ahead
and start placing down the blocks.

So you place down 
your block with your button,

and then from that,

you take a repeater output
set on two ticks

with a piston right here,

so go ahead and break that block 
and put a block in front of it,

and then right here is your redstone dust.

And that is it.

See?

Really quick pulse, it's awesome.

So this can used for opening a door

or triggering something really quick,

like if you want a one-pulse
out of a dispenser.

Now let's move on to the logic gates.

Now, these can be a little bit confusing,

but this one's quite self-explanatory.

So this is called the AND gate,
and that is because

both of these levers have to be down 
in order for this to give a signal.

If one of them's not down, it won't.

If this one's not down, it won't.

If they're both up, then it won't.

This and this have to be down
in order for it to get a signal.

So that's where the name
AND gate comes from.

This one is super easy,

it's just three blocks,

redstone torchs right here and here,

redstone dust,

and levers right here and here
with a redstone torch right there.

And there you go.

Here's your AND gate.

So now let's move on to the OR gate.

Now this one is really, really easy.

All you have to do is either 
this one or this one have to be pressed

and the piston will extend, 
giving an output.

So you can do both or either one.

So this one's really easy,

all you have to do:

place three blocks,
redstone on top,

the levers right here,

and your output will be right here.
So you can do that

and the piston will extend
or that one and the piston will extend.

And that's the OR gate.

Now this may very well be 
the most complicated circuit

in all these circuits I have shown you,
even though it's not that hard.

This is the T flip-flop.

This is very, very useful
in many redstone circuits,

you'll see it all over the place.

But this uses a pulse shortener 
from the last section that I showed you

to make this block extend,

and the sticky piston will actually
leave the block out there

because the pulse is so short.

So, as you can see, 
when I press this button,

powers the lamp.

When I press it again,
it unpowers the lamp.

So it's really simple, 
has a redstone torch down there,

which powers this block
and powers that lamp.

So let's go ahead and build it.

So you place the block down right here
with your button on it,

a two-tick repeater coming out of that,

a piston with a block on top,

and over here you wanna place
another repeater with a piston

and here is your block.

Down here, you wanna place 
a redstone torch,

and here is your output, that lamp.

So as you can see, 
when you push the button,

it turns on the lamp,

and when you push it again,
it turns off.

Now, there are many different forms
of each of these circuits,

this is just the one I chose
to show you guys today,

so there could be many forms of clocks,

many forms of pulse modifiers,
and many forms of logic gates.

There are a bunch of logic gates
that I didn't cover in this video,

but I just wanted to pick a few
to show you guys today.

So if you would like 
to see more of this series

of the redstone logic gates,
pulse modifiers, and clocks,

if you wanna know more redstone circuits,
leave a like and I'll definitely be sure

to make another one
if you guys are definitely interested.
