Rolf-David's Basic Logic Gate Tutorial 9, The T Flip-Flop. (Minecraft)

[marioornot]

for all the people who dont know where this could be used for. think bout binary counters, when you use this 2 items will count as 1 so you half the size of your circuit =) ( and binary counters can be used in factories befor you ask ;) )

[TheEmmanuelle1]

Couldnt you just use an RS NOR latch?

[sirdavva]

@TheEmmanuelle1 It all depends on what you want the circuit to do =)

[SepGamers]

In Beta 1.7, when Pistons are added, there is a OMGly compact T Flip-Flop!

[platinum9654]

I've always wondered what this is called, now I can put it in real circuits outside of minecraft. Thanks a lot!

[ruleram1]

thanks so much for this

[TheIronLaptop]

um no offence but this is piontless why dont u just use a lever

[sirdavva]

@TheIronLaptop This isn't pointless, you just don't know how to use it ;-)

[TheDrGuard]

@sirdavva I use the T flip flop when I have two inputs for something that needs to stay on or stay off, such as a secret piston door.. you flip the lever on to go in, but to turn it off from the inside you can't use a lever.you use a Tflipflop and buttons and your problem is solved. You can use the buttons and it doesn't get messed up because they are not in an off/on position and th 2 button inputs go to 1 tflipflop output. if that makes sense

[Flandyns]

@TheIronLaptop When you have a lever you can not use 2 or more levers on the same door, bridge or gate so on. But with a T Flip-Flop you can.

[Kompaaz]

@TheIronLaptop eehm what if u have a door opend by a leaver, you go in and then how do u close close it well heres your awnser use 2 button both conected to the same t-flip flop aaand taadaa

[Kompaaz]

@TheIronLaptop oooh you can conect a couple of of these (or the more compact piston ones wich rolf has made a tutorial of (a good one) ) if u connect a couple of these you get a  binary counter sooooo 2 awesome thing you can do (theres a shit ton more too)

[stratigist2]

what happens if you put a lever in in place of a button (would it pulse?)

[MLMeh3]

Just plain awesome... You pwn bro :)

[MrTechnoman31]

Im so clueless with the wiki's diagrams. thank god theres videos..

[CameraMan9258]

What you can do is hook up more than 1 button to the input so that you can, say, open & close a door from both sides using buttons.

[chandaman551]

This is no tutorial, you did not explain anything but what it does.

[MrBlackshotNoob]

I have no idea wat this can be used for

[sirdavva]

@MrBlackshotNoob An easy thing this could be used for is to open/close a door with one button. But there are alot more advanced things to use it for aswell =)

[MrBlackshotNoob]

@sirdavva thank you.But I think its a little too complicated. Thanks for replying :)

[PianoMan347]

@MrBlackshotNoob You can use this to make a ton of buttons act like one lever. So instead of needing to go back to just 1 lever you just wire up a button.

[lewissetter]

@MrBlackshotNoob Maybe something controlled by multiple buttons. Using multiple levers gets very complex very quickly. 

[hXc232]

@MrBlackshotNoob this is basically a 1bit memory unit, theoretically, with enough of them (and a shit load of other redstone wiring) you could build a rudimentary computer

[KillingForMoneyReal]

Hello evry 1 this is rolf david

[XMaster929]

Theres a really compact one, 3x2x2

[MinecraftPuzzleMaps]

So this is like an RS NOR latch but with only one input?

[ZC0W]

@MinecraftPuzzleMaps sort-of but i would suggest using a piston-based t flip-flop or the rs nor latch insted of this one due to space a time delay

[ummmkewler]

Thank you. This was all i needed to make a capture point map on minecraft.

[oOliveeeex]

Your a proper tramp mate.

[sirdavva]

@oOliveeeex I am a little slutty... but how did you know that! =o

[3991gamer]

Lol tripple RS NOR latch

[Sasbanonker]

I like your redstone tutorials, but I think you should revise this one, and explain in depth, what you're doing,while you're building it, and tell us what really happens with the button, and how the redstone works, to make it so it acts like a lever...

[Mastersofus1]

Norsk?

[vidmaker7]

Nevermind :D

[vidmaker7]

It doesnt work >_<

[tijnos44]

YOURE NOT EVEN EXPLAINING WHAT YOURE DOING IDIOT

[sirdavva]

@tijnos44 Glad you like it! =)

[ZC0W]

@sirdavva successful counter troll is successful

[SomeRandomZeke]

@sirdavva Can't you just make an RS NOR latch, get rid of one of the outputs and link the inputs together?

[MrSommar25]

en fråga är "t flip flop" samma sak som jk vippa? eller är det en annan sak X)

[xcosmicvoyagerx]

I am looking for a video that explains how the T Flip-Flop circuit works.

[humanityexists]

and then I rebuild it exactly as you have it... checking it about 5 times... and its not working...

[humanityexists]

RAHHHHH I HATE CREEPERS. I was making one of these using this tutorial (I can never remember how to make this T flip flop, and I not a big fan of the piston T flip flop unless I really need to save space), and then "sssSSSSS" BOOOOM destroyed the whole thing! FUCK YOU CREEPERS!!!!

[sirdavva]

@humanityexists Haha that sucks! ^^

[humanityexists]

@sirdavva yaa... it was funny later though haha, also i figured out what I was doing wrong, missed one little peice of sneaky redstone.

[sirdavva]

@humanityexists Always something ;-)

[DigitalMasacrer]

@humanityexists when building something time-consuming, why don't you go on peaceful?

[humanityexists]

@DigitalMasacrer pshhhhh whats the fun in that?

[DigitalMasacrer]

@humanityexists ok, next time try building with TNT ^^

[TheAllimania]

as i rebuildet it, i saw it is an rs latch. but weirdly setup..;)

[sirdavva]

@TheAllimania a RS NOR latch and a AND gate =)

[TheAllimania]

@sirdavva i always call them rs latch...hehe..its total clear, what i mean, because there is nothing like a rs "bla bla" latch

u know...so its anyways clear i mean the nor latch..or am i again mistaken?

[Gigahawk515]

For anyone who is wondering why you would use this instead of a lever, this can be used to put a " lever " in two places (ie. between a piston door) so that it can be used from both sides.

[TheAllimania]

@Gigahawk515 u could also make a xor gate i think

[Gigahawk515]

@TheAllimania not really because if you used buttons for inputs on a xor gate, they wouldnt keep the current in one state and would revert after the button decompresses. A lever can be used, but they look ugly.

[TheAllimania]

i think this is pretty useless. you could also hang the button up a rs nor latch, to have the same effect. and it would be smaller.

or am i mistaken?

[sirdavva]

@TheAllimania Yes you are mistaken. A T Flip-Flop is not the same as a RS NOR latch, if it was it would probably not be called something else... So no it's not useless either... A T Flip-Flop uses 1 input while the RS NOR latch needs 2.

[xMoreTx]

THIS IS GENIUS.

I love this, I just made my own and I researched it (after copying it from you) and it's so awesome - I would have never thought of a way to do it.

[kjetilott]

are u norwegian???

[mopmopmopmopmop]

The advantage this really has over a lever is using more than one input button. Normally using multiple levers to try to affect the same thing just doesn't work. With this both buttons would have the ability to open and close the door/piston. The issue is, I generally get trouble from inverters online so Id still rather use piston flow gates, even if it requires me to make twice as many circuits and have less neat buttons. No-glitch more effort > sometimes glitchy easier for me

[burnsieeee]

or you could just use a lever ?

[sirdavva]

@burnsieeee Boooooooooooooring

[Dearhunter43]

@sirdavva you and your 3X3X3 dirt house

[burnsieeee]

@sirdavva yeh im boring i dont take 5 minutes to set a fucking door to open

[mrpuffmyduff]

@sirdavva top comment in ur own videos....

like a boss!

[MrEkshin]

@burnsieeee The most important use for a t flip-flop is in counter circuits. Levers aren't useful for that. But thanks for you wry comment.

[burnsieeee]

@MrEkshin smd

[S4Player100]

cant understand anything ... sorry .. i think you explain like a math teacher :P

[sirdavva]

@S4Player100 My math teacher have always been exelent so I have to assume I were aswell? ;-)

no but seriously, redstone aint that hard, you just need to start from the beginning =)

[S4Player100]

@sirdavva i did start from the beginnin' ... but ... could you do a tutorial explainning and how to make all the gates and stuff ? because the wiki just explaines how to make and not what it does :(

Thanks for all !

PS : Subbed !!

[Sshark0]

@S4Player100 Just Place The Redstone As He Does -.-

[kkeejjgg]

this.. is sooooh confusing lol..;p

[MetalChocoboWielder]

Can someone do a schematic image file (like on the Minecraftwiki)

It'd make it easier xD

[Radical393]

thank you!

[themarathonseason]

Hi, loved the tutorial! I had a question~ If I wanted to use two buttons how would I make [Button A] open [Door A] AND close [Door B]. and the opposite: [Button B] open [Door B] AND close [Door A]? I want to toggle between them with this button idea. Any idea how? Thanks (:

[sirdavva]

@themarathonseason You could use a RS NOR latch and invert one of the outputs. And ofc the buttons will be connected to the inputs of the latch. Hope this helps! =)

[N2Cranes100]

what logic gate would i need to make a door open and close from two sets of buttons? Like one outside the door and one inside

[KiwiHardy]

@N2Cranes100 search rs nor latch

[DaMapleFilmMaker]

Why not just use a lever than this.. And i dont get the use of this. just use an rs nor latch. Please answer

[DisguisedNinjas]

@DaMapleFilmMaker It's one input and one output instead of two inputs and two outputs.

[DisguisedNinjas]

@DaMapleFilmMaker Also, levers have to be manual. This type of gate can be activated from other redstone circuits. It's like the advantage of transistors over switches in making computers.

[KiwiHardy]

@DaMapleFilmMaker with a lever you cant use multiple lever to open/close

but with flip flop you can use like as many as you want to open/close

[sirdavva]

@DaMapleFilmMaker As kiwi said, with a flip-flop you can hook up as many buttons as you'd like, and what ever button you press will change the state of the output. And as for the diference between a flip-flop and a rs nor latch... well the rs nor latch has two buttons that needs to be pressed to change the state, while with a t flip-flop you only have one button. A T Flip-flop is basicly a RS NOR latch and a AND gate together.

[MetalChocoboWielder]

@sirdavva ALSO, with Pistons in the vanilla, you can make traps that go on/off for your survival maps and such. Pressure plates work with this to!!

[lupusarcanus]

Rolf, your explanations are wonderful. Thanks so much for your time.

[sirdavva]

@lupusarcanus My pleasure! most of my videos I do to try and "teach" peaple =)

[aewilson95]

So basically this is just an RS NOR latch with only one input and output?

[sirdavva]

@aewilson95 Well I guess you kinda could say that. But they are very useful in different situations =)

[XxBulletproofxX1]

forgive me for the lack of wisdom of whats the point of logic gates?

[JakeMinecraft155]

I made a T flip flop but when i switch it it blinks a like a clock and turns off ??? HELP ME! :P THANKS!

[sirdavva]

@JakeMinecraft155 It's hard to help you with stuff like that since I can't see YOUR circuit =P

[coolguyflex]

Lol, before I saw this tutorial I had no idea that there was a thing called t flip flop gate. So I made something with the same effect using pistons. It worked but it was slow and made A LOT of noise

[dudestroier]

ok i did this with one RS NOR and one and gate witth two diodes

it takes a lot less spaca

[ProfessorPenquin]

Does this work with pressure pads as well as buttons?

[Popsical246]

Isn't this just a super complicated lever?

[parrottmedia]

Awesome. I never thought I'd use something like this, and what do you know, I end up using it. Many thanks. It works like a charm.

[eleongo]

i will use this to create an elevator using button as switch

[Fidchelle999]

I'm using this with the better then wolves mod so I can toggle the elevator to the bottom of the abyss I'm transforming on and off. I heard of ways to make a rail T Flip-Flop. I'm Investigating it ATM. Thanks for the tutorial.

[sirdavva]

@Fidchelle999 Haha the wiki can get a little overwhelming ^^

[ultra695]

your tutorials are so helpful

[RSSDFTW]

please do a jk flip flop tut

[SPTproduktion]

@jakeycool8899

a lever is in some situations more effictive, but if you are on a pvp server and want an alarmsystem you actuly need a flipflop for this.

for example you had an iron door and infront of it a pressure plate. The enemy will walk on the plate, to come through the door, but the you also know he is comming.

[sirdavva]

Bla bla bla ofc you can use a lever instead of a T Flip-Flop but there are more things you can do with a T Flip-Flop as well, this is a just a simple example! You have to use your imaginations! (Directed to everyone posting comments like "omg why do it like this when you can just use a lever")

[jimmybrite]

@sirdavva T flip flop & Pistons and lava activated by a pressure plate makes for a nice trap. I've been looking for a tutorial on how to "transform a pressure plate into a lever" but I didn't know how to word it. This is great!

I looked at the wiki, but I just dose off whenever I'm reading that section.

[erocker0546]

@sirdavva I have found this so useful in the 1.7 patch. I have a bridge that relies on switches, but the only way I had figured out to close the bridge once across was to physically block the power with a block. It worked, but is impractical for multiplayer. All i have to do now is figure out a good way to hide this in a building, and I'm going to have a sweet home base. Thanks a ton!

[jakeycool8899]

... I find a lever to be more effective.

[IHavePockets]

Can you explain how and why it does what it does?

[sirdavva]

I will be doing a new video of a Compact T Flip-Flop in the enar future. It's only 3x3x2 if I remember correctly!

[RokuNoRaiden]

Damn your accent is awesome especially when you say A,B or C!!

[MIN3CRAFTGAM3R]

Watch my compact T-Flip Flop Vid :) its a WAY more compact than the normal T-Flip Flop

[ThePysen96]

why not just use a lever?..

[hugh705]

why can't you use two buttons with a rs nor and an inverter on the door

[sirdavva]

@hugh705 Cous then I'd need 2 buttons =)

[thesmellanator]

@THEnicknackGAMER yes its called a monostable circuit

[aristos1231]

we can place cobblestone above a stick i believe and we dont need to use that space

[sirdavva]

@aristos1231 Acually, you place the cobblestone UNDER a stick.

[deoneothe1]

and then you put this there and this there and this there and this there and this there. :)

[coolglen201]

it helps to explane what the hell u are doing "ok put this here this block here redstone here" and you do it to fast to follow

[PURPLERIDDER4]

you are my redstone hero :)

[Maximinators]

You can also do this with a RS NOR Latch , right?

[sirdavva]

@Maximinators Well it's not really the same, but there are similar in some ways

[gurkmannen37]

Vad skulle sägas om bara en minnescell?

[sirdavva]

@gurkmannen37 Det blir inte samma sak :)

[gurkmannen37]

@sirdavva Oj märkte det xD måste då ha någon slags resetter :D Btw dina videor är jätte gosiga :)

[xHouseyx]

Great video. You have a very nice voice to listen to.

[masterman673]

HOW THE FUCK IS THIS BASIC!!

[Samocoptor]

@masterman673

It's probably called that because it is literally the most basic version, either that or it's just the series title.

[masterman673]

@Samocoptor fair point

[Sadotu]

Can this be simplifies by repeaters from the newer version?

[LickyDisco]

Would you be able to connect double doors (Two doows right beside each other) to this and have them both open and close at the same time?

[sirdavva]

@LickyDisco Yes indeed! search for "Rolf-David's double doors with buttons and power switch (Minecraft)"

[Glo0ze]

why would u make such a complicated T-FLip-Flop if u could just use a lever? =)

[Seriath1]

@Glo0ze i was thinking the same but i guess its good for those who dont like levers and love buttons :))

[ixcaliber]

@Glo0ze for opening a door its... well... pointless. But the output could be used for something else, like a counter, which then can be turned into a binary calculator, which then can be turned into a digital calculator.

[crushgear64]

@Glo0ze

it allows you to do further things to the signal, a lever can be limiting.

[Nobody5230]

So its a RS NOR latch, except more complicated?

[sirdavva]

@Nobody5230 Not really. This flip-flop has ONE input and the output changes when I push the singel button. A RS-NOR latch has TWO inputs and you have to toggle between them to change the output.

[Maximinators]

@Nobody5230 Yea ,actually it is and RS nor needs 2 buttons 1 to change and memory and another to reset. with inverters you then can create than when the output is 1 it has to use the reset next time (THE RS its the circuit in the middle)

[linerage]

... What IS this? O_O

[Fliping8]

Will you make any more of these?

[ericfam01]

its official, everything/person from sweden is amazing

[sirdavva]

@ericfam01 Frank Zappa said: Fuck The Swedes! Cous they're beautiful.

[ronikinglll]

@sirdavva hey um do you have real knowledge of logic gates like is part of your job??

[sirdavva]

@ronikinglll not really. I did read a basic cours in electrical engineering. Though we did not play around much with logic gates.

[ronikinglll]

@sirdavva ah kk its just nice knowing that people know stuff that my teachers talk about all the time (im in school in the electronics engineering)

[sqrtMinus1LuvU]

in fact this is not just for aesthetic values: if you place a redstone "wire" under a block with a lever on it, it won't be affected, but if you place a piece of redstone under a block with a pressure plate (works as well as a button) on it, it _will_ be affected. Hence this can be used for traps or something as it 1) does not require special input (just step on it, intruder may activate it unintentedly if placed cleverly) and 2) does not make anybody see the wires (ok that's aesthetic ^^)

[Sinaler]

What is wrong with an RS NOR? Can't you just hook a button to both inputs?

[illznik2]

@Sinaler I tried to do this too. Even if one of the signals from the button is inverted, as soon as the button "turns off" the opposite signal is sent, switching the RS-NOR back to it's original state. The RS-NOR latch's function is to only accept a positive input when its state is negative, and vice versa. Since a button always switches back and forth, both the positive and negative inputs would be applied each time. Hence the need for two seperate buttons, or a flip flop.

[probscus]

@Sinaler i kno right it would save a lot of space all you need is 2 buttons aye

[joshtemplin3]

1 person hates minecraft.

[APinkBaloon]

why a t flip flop and not a lever or a rs nor?

[MusicGaming1]

are you from sweden?

just asking :)

[sirdavva]

@MusicGaming1 Yes I am

[MusicGaming1]

@sirdavva :D

[Buck90wl]

Finally my 32 Button Lock can continue!

[sirdavva]

@Buck90wl Heh, 32 buttons... sounds big! make a video of it when it's done.

[TheBenny126]

er du norsk eller? rolf david.

der høres son ut

[NorwayHack]

@TheBenny126 Han er svensk ^^

[indago9]

Isn't the T-Flip Flop just two RS-Nor latches stuck together?

[iD0ct0r]

@Grglr1

If you click on "More Videos", at the description, and qcroll down a bit, you'll see a "Subscribe to "X" " button.

[BDtetra]

I wish somebody actually does a video that really explains how the T flipflop works. I know its difficult, thats why I don't understand why exactly it works, but I really would like to see one.

[middaystars]

Very good!

[Grglr1]

Hey man your vids are seriously a blessing! I can't understand any of the explanations on the wiki, so these really help! I watch on my iPhone mostly, so I wasn't able to sub earlier, but you got a new sub now! XD

[sirdavva]

@Grglr1 I am glad you have found them useful!

[SpAz9937]

Great work, Looks amazing

[bitaprey]

Awesome!!!!

[Subj3ctToChang3]

Thanks, could you give some more examples of where this might be useful?

[zelodec]

@Subj3ctToChang3 u can use 4 T flip flops (each t flip flop connected to each other) to build an binary counter =P it will count from 0 to 9 and then from 0 again........
