Redstone is Minecraft's wiring. A redstone signal travels through a circuit and switches things on and off — lamps, doors, pistons, dispensers. Everything you build in Redstone Studio comes down to moving that signal from one place to another and reshaping it along the way.
Signal strength runs 0 to 15
A redstone signal isn't simply on or off — it carries a strength from 0 to 15. A power source like a lever or a redstone block outputs the full 15. That number is the currency of every circuit: components read it, change it, and pass it along.
Dust weakens the signal
As a signal travels along redstone dust it gets weaker. Every block of dust it crosses drops the strength by 1. Start at 15, and after fifteen blocks the signal has decayed to 0 — off. That is the farthest a bare dust line can carry before the signal dies out.
- A lever, button, or redstone block outputs strength
15. - Each dust block the signal crosses costs
1strength. - At strength
0the wire is off and nothing downstream reacts. - A repeater resets the signal back to
15, so you can keep going.
Powered blocks: strong vs. weak
When a signal reaches a solid block it can make that block powered, and a powered block passes the signal on — but how it does so matters. A weakly powered block lights adjacent dust, yet on its own it won't trigger a repeater or another component pointed into it. Strong power — from a redstone torch beneath a block, or a repeater aimed into it — drives both dust and components. When a circuit looks right but the last component refuses to fire, this is usually why.
Everything runs on ticks
Redstone has its own clock. One redstone tick is 0.1 seconds (two game ticks). Most components react instantly, but a repeater adds 1 to 4 ticks of delay and a torch takes 1 tick to flip. Timing circuits — clocks, pulse shapers, sequencers — are built entirely from these small, predictable delays.
