# AND
**Category:** Gate
**Tier:** Basic
## Purpose
The AND gate outputs a positive pulse only when ALL connected input sensors are active simultaneously.
## Visual Reference
```{raw} html
```
## Runtime Behavior
**Inputs**
- **Input 1** (Boolean): First input signal
- **Input 2** (Boolean): Second input signal
- **Input 3** (Boolean): Third input signal (optional)
- **Input 4** (Boolean): Fourth input signal (optional)
**Outputs**
- **Output** (Boolean): True only when all inputs are true
**Properties**
- **gate_type** (option, "AND"): Logic gate type (can switch between AND/OR/XOR/NAND/NOR without reconnecting)
**Execution Behavior**
**Tick Behavior**
- Evaluate all connected inputs
- Output is true only if ALL inputs are true
- Generate positive pulse on rising edge (false->true)
- Generate negative pulse on falling edge (true->false)
- For invert behavior, use NAND gate instead
**State Changes**
- State becomes ACTIVE when all inputs are true
- State becomes INACTIVE when any input is false
- State transitions trigger appropriate pulses
**Edge Detection**
- Positive pulse: When output transitions from false to true
- Negative pulse: When output transitions from true to false
**Examples**
**Basic Usage**
Connect two sensors (e.g., Keyboard + Mouse) to AND gate inputs. Output activates only when both sensors are active.
**Advanced Usage**
Use with 4 inputs for complex multi-condition logic. Enable Invert for NAND behavior.
