Tutorial 2: More basics



Welcome back to the second part of the basic Redstone tutorials. In the last part you learned about some of the components in Redstone circuits, aswell as the block range of a current, and how to build a simple NOT gate (Aka an Invertor).

In this tutorial, I'll cover the range of inputs you can use, aswell as a second logic gate, the double NOT gate, also known as the Extender.

So to start it off, there's a few ways you can input a signal:

Redstone Torches

As has already been mentioned, these give out power whenever they are unpowered themselves. A Redstone Torch receiving power stops giving it out.




Levers

These have two states, OFF and ON. When flicked, they remain in that state until flicked to the opposite state.



Buttons


These also have two states, OFF and ON, but their default signal is OFF. When pushed, they give out an ON signal for a brief amount of time, before switching off again.




Pressure Pads

Like the two before, these can be either ON or OFF. Their default signal is the same as the button, OFF, and this changes to on when either;

They are stood on by the player or a mob or;

A block or item is dropped onto them.

When they no longer have any weight on them, they return to the default OFF setting.






So there's your inputs, meaning it's time to show you the second basic logic gate, the double NOT gate, aka the Extender.



The Extender is essentially two NOT gates in sequence, but condensed down to save space. This first reverses the incoming signal, then reverses it again, leaving the output the same as the input. Doing this allows you another 15 blocks of current, meaning it's useful when creating long Redstone trails.

In the 3rd basics tutorial I'll cover the variety of outputs you can have in your circuits. Thanks for reading!

  1. Thanks. I remember being confused with redstone when I first discovered it. Though I am a redstone genius now, this looks like an extremely easy, and short tutorial to follow, keep up the good work.

  3. I liked this. It really helped me understand how to extend redstone power. I just recently tried opening a door 60 or so blocks from a lever, (made a mistake and forgot the dust on the actual extender itself), then managed to get a working long range door lol

  5. dude thats not nice this guy made this tutorial so people like me can learn to use redstone. So if you already no how to then don't diss this tutorial!

  6. Wow. Can't believe you forgot that you can't drop items on a stone pressure plate to make it work! That's only on the wooden ones!
