1. OR Circuit
An OR circuit is a circuit in which the output is 1 when either input is 1. An OR circuit is also called a logical OR.
Truth table
The truth table for an OR circuit looks like this. When either input is 1, the output is 1.
Circuit symbol
The circuit symbol for an OR circuit has a pointy end and a rounded left end, like an arrow.
Logic circuits made in Minecraft
The OR circuit created in Minecraft looks like this. The lever corresponds to the input and the lamp corresponds to the output.
2. AND Circuit
An AND circuit is a circuit in which the output is 1 only when the two inputs are both 1. An AND circuit is also called a logical product.
Truth table
The truth table for an AND circuit looks like this.
Circuit symbol
The circuit symbol for an AND circuit is the letter D extended horizontally.

3. NOT Circuit
A NOT circuit is a circuit in which the reverse of the input is output: a 1 is input to produce a 0, and a 0 is input to produce a 1.
Truth table
The truth table for the NOT circuit looks like this.
Circuit symbol
The circuit symbol for a NOT circuit is triangular in shape, with a small circle at the tip. Also, unlike AND and OR circuits, it has only one input.

4. NAND Circuit
The NAND circuit is a circuit that adds a NOT circuit to the AND circuit, and outputs the inverted value of the AND circuit output.
Truth table
The truth table for a NAND circuit looks like this.
Circuit symbol
The circuit symbol for a NAND circuit is also an AND circuit with the circuit symbol for a NOT circuit.
Logic circuits made in Minecraft
The circuit symbol for a NAND circuit is also an AND circuit with the circuit symbol for a NOT circuit.
5. NOR Circuit
The NOR circuit is a circuit that adds a NOT circuit to the OR circuit, and outputs the inverted value of the OR circuit output.
Truth table
The truth table for a NOR circuit looks like this.
Circuit symbol
The circuit symbol for a NOR circuit is the symbol for an OR circuit with the circuit symbol for a NOT circuit.

6. XOR Circuit
In an XOR circuit, if two inputs have the same value, the output will be 0, and if two inputs have different values, the output will be 1. An XOR circuit is also called an exclusive logical OR.
Truth table
The truth table for the XOR circuit looks like this.
Circuit symbol
The XOR circuit symbol is an OR circuit symbol with an arc on the input side.
