How Do You Use Morse Code in Minecraft?

Build a redstone telegraph: wire a lever to a redstone lamp or a note block, then switch it on briefly for a dot and about three times longer for a dash. Morse has no built-in use in the game, so it's a player-made system, but it works well for sending messages between bases.

Build a basic telegraph

The Minecraft Wiki's telegraph tutorial uses a lever as the sender and lists the other parts:

Part	What to use
Sender	A lever, since you control how long it stays on
Wire	Redstone dust, with a repeater about every 15 blocks
Light receiver	A redstone lamp
Sound receiver	A note block

Skip buttons for sending. A button stays on for a fixed time, about a second, so every signal comes out the same length.

Sending a message

Flick the lever on and straight off for a dot. For a dash, leave it on for a count of three. Pause between letters and pause longer between words.

Your partner watches the lamp or listens to the note block and writes down what they get. Keep the alphabet open while you learn, or check the message in the translator. Experienced builders go further, with circuits that measure pulse length and light up letters automatically.

The hidden BEHIND message

One of the game's cave ambience sounds hides real Morse. Slowed down or viewed as a spectrogram, cave sound 21 spells -... . .... .. -. -.., which the Minecraft Wiki's easter egg list decodes as BEHIND. When players asked Mojang's audio director about it, his only reply was "Creepy," so it's never been officially explained.
