Computer Logic Gates in Minecraft (Only Redstone and Torches)

Hello so I’m going to be doing some computer science within minecraft so if you don’t know what logic gates are then this is the perfect video for you so I’m gonna be showing this as if it was a normal computer now in a computer you have an input you have something to

Carry the signal just an object is to set it on so it could be the PCB or something you have this here which is a not gate in itself and then you have the output so how about we get started straight up the input goes into the wire

And happens to the output and that’s how it works a lot of people know that now let’s say we want to invert it input goes into your not gate which is this redstone torch here going into this output so this here is inverts the signal just with these two sections here

You could do absolutely everything there is in computers that’s how computers works just a line that turns on and off off being zero on being one so from this let’s move on to the next section so an or gate all it does is connect two signals together

Bringing in to the output that’s so that’s called the or gate so if this one or this one is on then the outputs on and that goes for both of them as well if we’re going to make a nor gate which is an OP gate mixed with an or gate he’s

Gonna do an or gate connecting this up to it not gate to the output so now if one of these are on or both then the output will turn off now then we will move on to a NAND gate or an and gate sorry so that’s built like this with in

Minecraft I’m going to build the bigger version after it first I’ll start with a small one then the big one this here is an and gate I forgot to put me in this signal so if this one on nothing happens this one’s on nothing happens it only

Turns on if this one ended this one is on easy way to remember it now the long version of a NAND gate is just simply you have the input going into a not gate another knock aid those are connected with an or gate into another knob gate and that there

Makes your and gate there okay next is an and gate okay so all that NAND gate is is an and gate but inverted and how you can do that he’s just like this here so this one Elaine turns off if both the inputs are off now a long version of

This isn’t is to not gates connected with an or gate into an output that’s a long version okay next we’re moving on to the bit more complex ones and we have an XOR gate so how you build an XOR gate it is a bit more tricky

You need an and gate and gate here you need the not gates connected with or gates and each of these go into another not gate converting the signal once again and that goes into an or connected them two together into the output how this works the output will only turn on if the

Inputs are different so you see it turns on there but if you do the both the same time the output turns off okay so the long version of this is a bit this is still pretty complex with this what these type of ones here so first you

Want to make the an gate as I showed the you before which is down here you connect those with an or gates into another not gate and there you have your and gate you want to run this over here into these inputs like this then these

Here will go into some more another not gate and then these will connect together with an or gate into the output and that there is your X or the long version perfect now in next thing you have is your X nor gate so that’s the X

The X or gate connected with a not gate so I’m just going to build that here okay so that there is the xor gate now you want to connect this into a not gate like this and that makes the X nor gate VX not all they have that there that

There and then both of them this turns on so I mean turns off if both the inputs are only turned on if both the inputs are the same so in if they’re different it turns off just like that okay now we’re getting any even more complicated so the next thing we have is

The T flip-flop now this is a it’s a bit tricky one to do a lot of people I think it’s pretty easy because I’d usually get the piston like this see if I got this right cause if this is directional okay well I didn’t okay so this is the T

Flip-flop for the people you would usually use but this we can’t use Pistons we only have the redstone torches in the redstone so to make this one this one is a bit tricky we need an end gate like this I’m gonna make the compact version first and then

I’ll make the bigger version so this is the end gate now go a few blocks over build another and gate actually for this end gate I’m not going to put the inputs on I have to connect these two together though with the button the point of AET

Fit floppy is to turn a input which turns on them back off into a table level so it’s a toggle switch so chuckle see if I flop is a toggle flip-flop I don’t know something like that so you have the two and gates and these connect

In two and nor gates so you have an or gate is not all so it’s a nor gates over there that’s the e just into a knocking so you have it connected like this now okay now what you want to do is run the input into all the output from here into

The second input of the end game just like this because then what you want to do you have to run you have to run the output from here into this one kind of like crossing over a bit and that can’t be connected and then you have to actually I’m gonna redesign this a

Little bit such a run it’s like this okay now so those are connected to the all here now we have to connect to this since this is not this done okay we’re going to make it into a not all gate so we have the two inputs we can’t connect

To these two together so you have to run it from the output of this one here and then we have to get the output from this one and we have to jump the line a bit just like so run it in to this one here let me just block this off now this

Should give us our T flip-flop so I’m going to so theoretically when I press this button you should go from this one to this one you should have gone a bit of a clock like a bit of a cycle and then eventually it will land on this one

And I can repeat it the other way and make it this one turn on there we go and that’s it there so to expand this a little bit we just going to start with the input going into a not gate here and I’m gonna move this over a little bit

The input going to this and not gate here and this not gate hook up a second not gate like this creating the end gate make an or and then the not gate here just to like so now what you want to do is take the this

And put it into an or gate like this run this input or sorry run this output all the way back to this input here and you just rough want to repeat the same with the next one like this and run it all the way back into this input here just

Like so and they want to take the again I’m going to do this then I want to take the output from here and I want to run it into the input here and then the same with this one here go jump it over and then this one’s

Gonna be a bit tricky I have to run at night over into this one but these lines can’t be connected like that now pretty much this should work the exact same it worked absolutely perfectly so that’s a large version the next thing I’m going to do is a repeater so these before

Repeaters were actually added these this is what they look like you have an not gate throwing into another not gate so that’s a repeater there it works absolutely fun now the reason a repeater it extends or it’s a redstone signal and it also works as a delay

That’s a normal repeaters do so using this we’re going to make a clock how you’ll make a normal clock is you would just get the repeaters here connect those together into any important like that but for this one is going to be a bit tricky you will see so you have the

Repeater here and this is going into another repeater just like this and it connects like that hopefully this works there we go that this repeater and they did they do burnouts because of how redstone torches work okay that’s repeated next is the RS nor latch so not all latch so a lot of

People already know this one you just connect them the two just like this know what’s called an or less maybe it’s because you have the all going in here it isn’t all so you have the all going into like this and then you take the output from here here and here so these

Are meant to be done with button so that’s researcher switches over like that that’s it there so basically this nothing happens until this is reset so worse I think I’m gonna leave off on the RS nor latch this here so using this you can make an entire computer well these

Are held any computers work this just basically turns into all computers or computers are their fancy calculators they’re very good at adding numbers together extremely quickly and work off a basic clock but some calculations take 10 clock cycles some take 50 some takes thousands of few thousand that’s why the

Clock runs in gigahertz that’s a billion ticks per second look I billion Hertz the second I hurt is when is one clock cycle or just an input on then off again that’s a hurt now I challenge somebody to make a computer using nothing but the input the line the block torch and the

Output so I challenge someone to make it can be like this now I shouldn’t be too difficult that’s about it I hope you enjoy it if you enjoyed this just go ahead and hit that like button and maybe even shoot me a subscrib believe you’d like to you have

A good day I’m gonna go now see
