Redstone Dust, Torches, Repeaters, and Blocks Explained | Minecraft Redstone Engineering Tutorial

What’s up guys today we’re going to go over all the properties of redstone dust redstone torches redstone repeaters and redstone blocks to hopefully help you build your own redstone circuits all right so starting with redstone dust redstone dust carries redstone signals the signal strength of the redstone dust

Is a maximum at 15 and then it goes down by one every block that it goes away from the source so we have 15 14 13 12 all the way down to zero which is completely off redstone dust powers any opaque block that it’s on top of so in this case the

Gold locks are being powered uh and then in turn the gold blocks power the redstone lamps here the dust also powers any block that’s facing into so in this case this lamp right here the dust is powering because it’s facing into it whereas these two blocks are not getting

Powered because the dust isn’t facing into it this also goes for any components that force the dust to go into it such as repeaters and comparators um so this rule still applies it’s just these guys force the dust go into it which is why we can do it on the side rather than

Doing it at the end like that redstone dust can travel up and down one block at a time so it can go up the staircase and down the staircase it can’t do any more blocks than that so it can’t go up two so this isn’t connected

And it can’t go down to this isn’t connected either it also can’t go up one block if there’s an opaque block cutting off the corner right there like this so this is not connected to this guy because it’s getting blocked off by this opaque block however with transparent

Blocks it can actually go through the corners but it can only go up so this goes all the way up whereas if we break that and do this it won’t go down for some reason and this goes for any transparent blocks so we can also do it with glowstone

Because for some reason glowstone is transparent and it again has the same property so you can’t go down but you can go up all right so moving on to redstone torches torches provide a power source of 15 and will power any block that it’s adjacent to except for the block that

It’s on top of so this lamp is not on because this block is not powered this also goes for if it’s on the side so if we do this this block is not powered however it will still power all the blocks that it’s around torches also have the unique property of

Inverting the signal that goes into the block that the torch is on top of so right now that is the gold block um the signal on the gold block is off which means the torch will be on if we turn it on then this torch will be off it

Doesn’t matter how we power the gold block so we could just easily go add a repeater into it and it will still do the same thing however be careful of doing something like this because you can actually short out your torch by turning it off and on

Too fast and what’s happening here is that this torch powers this block which then powers the redstone which then inverts this block which then inverts this which inverts this and then it just goes on and on until it turns off completely redstone torches also take one redstone

Tick in order to do this inversion all right so now on to the redstone repeater the repeater will output a signal of off if the input’s off and it’ll output on if the input is on however it’ll output a signal strength of 15 if the input is any signal

Strength that isn’t zero which allows us to essentially distance extend like this where redstone dust alone can’t make it all the way to the end here because it’s longer than 15 blocks whereas if we put a repeater in the middle we can make it all the way to the end because this

Isn’t the signal strength of 15 but this is a signal strength of 15 which then essentially resets the distance that we can travel repeaters will strong power any block that they’re facing into like this which means that they’ve powered not only that block but any block around it including redstone dust

However unlike redstone dust repeaters do not power the block that they are immediately on top of like this whereas if this is redstone dust this is powered repeaters also allow you to adjust the delay that it takes for the inputs to go to the outputs so there’s a minimum of

One redstone tick which is the default and then every time you right click it increases by one redstone tick up into four redstone ticks so we can see here that these lamps turn on at different times with their respective delays however they also turns the pulse length

To a minimum of whatever the delay is so if the pulse length on the input is shorter than the delay then the new pulse length will be whatever the delay is so we can see that by doing a really fast delay here the left one is on for longer even

Though they start at the same time because these all have a pulse length of one whereas this has a pulse length of four you can also lock repeaters into a certain state by putting another repeater sideways into the repeater that’s gonna get locked so if we turn

This repeater on we can see that just acts normally however if we turn on the repeater on the side it will lock it into the state that it’s on so we can now turn this off and it’s locked into the state and it will remain locked

Until the side repeater turns off now on to redstone blocks redstone blocks are a movable block that is always powered so we can move it into the middle of all these lamps and then all the lamps turn on however unlike a lot of other power sources the redstone block doesn’t power

Adjacent blocks so you have to have your redstone components immediately next to the redstone block in order for them to be powered alright guys that’ll be it for this video i hope you found something of value here i wish you a wonderful rest of your day and i’ll see you next time
