How to use sculk sensors

Tutorial Difficulty: 4/10

When sculk sensors were announced at Minecraft Live 2020, there were three types of response: "Meh, it's not frogs, and I want frogs" from the people who want new mobs, not blocks, "Oh, that's cool" from the casual redstone users,  and "AAAAAAAAAAAAAAAAAH" from the people who really, REALLY love redstone.

You see, the sculk sensor enables one really cool feature: wireless redstone. Sculk sensors can detect vibrations, which mean they can complete a circuit just by sensing movement or change nearby, instead of requiring redstone dust paths to activate them. The types of things they can sense range from something as quiet as a bat flapping its wings, all the way up to the noisiest things in Minecraft: explosions and lightning strikes.

The sensors are part of the deep dark biome, where the Warden — who also moves around by detecting sound — lives. As you can tell by the name, the deep dark is very, very dark, and much like real-world nocturnal creatures like moles, shrews, and bats, everything that lives in the deep dark survives without the use of sight. Moles use smell and bats use echolocation, but sculk sensors use soundwaves. Isn't that cool?

I'm more of a builder than a programmer, so I won't pretend to understand the potential applications of wireless redstone, but luckily for me (and you!), BlenDigi has put together some "simple" sculk sensor builds to get us started.
