Description (From Recipaedia)
Logic AND gate. Has two inputs on the sides and one output. The output is 1 when both inputs are 1, otherwise it is 0. Can be placed on any surface and rotated to desired orientation.
Crafting
Requires 4 germaium crystals and 3 copper ingots. You get 4 AND gates.
Hooking It Up
Connections
The output is on the side of the block that has the 'rounded' part of the symbol. The inputs are the 2 sides next to that side. The opposite side has no connections.
Graphical Symbol
AND Gate has 2 inputs [ Labeled A and B in Red ] and 1 output [ In Blue ]
Truth Table
Truth Table shows all input combinations and how the output responds.
| Inputs | Output | |
|---|---|---|
| A B | Y | |
| 0 | 0 | 0 |
| 0 | 1 | 0 |
| 1 | 0 | 0 |
| 1 | 1 | 1 |
To demonstrate this, I am going to represent 0 with Blue and 1 with Red.

Notes
- AND gates are primarily digital devices but will operate on analog signals. It performs a bitwise AND. This allows for more compact and interesting circuit designs. See Using Analog Signals.
- AND Gate finds the Minimum between 2 binary digits, unlike the Logic OR Gate, which finds the Maximum.
