NOT GATE (INVERTER)
The simplest logic gate. Inverts the input signal, when input is ON, output is OFF, and vice versa. Built with a single redstone torch. The foundation for all other gates.
Truth Table
| Input | Output |
|---|---|
| 0 (OFF) | 1 (ON) |
| 1 (ON) | 0 (OFF) |
How to Build
- 1Place a solid block (e.g., cobblestone).
- 2Place a redstone torch on the output side of the block.
- 3Run redstone dust into the input side of the block.
- 4When the input is powered, the block becomes powered, turning the torch OFF.
- 5When the input is unpowered, the torch stays ON and outputs signal 15.
Build Variants
- ▸Torch on block (classic, 1 torch, 1 block)
- ▸Torch on wall (attached to side of block)
- ▸Comparator-based inverter (subtract mode with side input of 15)
