OR GATE
Outputs ON when ANY input is ON. The simplest multi-input gate, just merge two redstone dust lines into one. No torches needed for basic OR functionality.
Truth Table
| Input A | Input B | Output |
|---|---|---|
| 0 (OFF) | 0 (OFF) | 0 (OFF) |
| 0 (OFF) | 1 (ON) | 1 (ON) |
| 1 (ON) | 0 (OFF) | 1 (ON) |
| 1 (ON) | 1 (ON) | 1 (ON) |
How to Build
- 1Run input A as redstone dust toward the output point.
- 2Run input B as redstone dust toward the same output point.
- 3Where the two dust lines meet, they naturally combine into an OR gate.
- 4If either input has signal, the output will be powered.
- 5For isolation, use repeaters on each input before merging.
Build Variants
- ▸Direct dust merge (simplest, just join two lines)
- ▸Repeater-isolated OR (prevents signal backflow)
- ▸Multi-input OR (just add more lines to the merge point)
