Minecraft: Logic gates - Redstone Circuits Minecraft guide, tips
Logic gates: NOT, AND, OR, NOR, NAND, XOR, XNOR, Pulse circuit, Rapid pulse circuit, Repeater - how to build? How they work?
Last update: 12 July 2020
Logic gates in Minecraft are devices that perform certain logic functions. Thanks to them, you will be able to construct systems based on conditions, which can be defined with logic statements, of a definite structure. You build these using the leveler, red dust and red torches. Below, you can find available constructions of logic gates.
NOT
The negating "NOT gate". Its function is to negate the signal. For example: after the button is pressed, instead of turning on the lights, it will turn them off. The basic for such a negation is to place a red torch on a brick's side, through which the signal runs. Just like in the above screenshot - although the leveler is in its OFF position, the lamp is on.
AND
The functioning of the AND gate, i.e. conjunction, is that the output signal is positive only if both of the switches are in the ON position. Switching only one of the switches on is not enough to initiate the signal.
OR
The OR gate, i.e. alternative, is simply a combination of two, or more, signals. Whenever any one, or several (or even all) switches are active, the lamp turns on. Does not require red torches.
NOR
NOR is a negation of an alternative, the so called double negation. It looks like a typical construction of the OR gate, you only need to put a red torch at the output, on the side that serves as a negation. Its functioning is that if, any of the levelers is active, the lamp remains OFF - both of them need to be activated.
NAND
The NAND gate (disjunction) realizes the condition that the lamp is ON, apart from an occasion on which both switches are ON.
XOR
The XOR gate (excluding alternative) corresponds to the "only or" statement. It functions in the same way as OR, with ignoring the positive signal on the output, when both of the switches are active.
XNOR
The XNOR gate, also known as the equality gate, works as follows: the output signal is positive only if both switches are ON or OFF. It does not emit the output signal if only either of the switches is on.
Pulse circuit
A pulse circuit is a circuit, which results in variable emission of signal. Using such a circuit results in turning the receiver on and off. You can use it, e.g. to obtain the effect of a blinking lamp.
Rapid pulse circuit
Rapid pulse circuit is a circuit similar to the pulse circuit, but acting with much higher speed (with a traditional lamp, even the individual blinks are indiscernible).
Repeater
Repeater is constructed like the double negation and it cane supplant the ready-made element of the same name It is used for transmitting the signal over a distance larger than allowed by a single switch/torch (more than 15 redstone bricks).
