Logic Gates

Hello! This is tHeRePeater. Today I will talk about custom switches, probably better known as logic gates. Logic gates are in the case of a piston door that need an open and a close button/lever/pressure plate on both sides. Continue reading to truly understand! (A=1st lever, B=2nd)

NOT Gate/Inverter.



This gate basically turns an ON signal to an OFF signal. It's used for things like the following:  You place a redstone torch under a piston, and the piston activates. You then attach the current to the lever. You want the button, when hit, to make the piston turn on, not off. So you add a NOT Gate, and all if fixed! That was a bad example, but you get the point. So, in the end, a lever flipped ON will power your whatever OFF with an inverter, and vice versa.

OR Gate

The simplest of all, this gate makes something, a steel door for example, be able to be actived by two different standard switches. Say you want to open your door with a button. Bam, there, you hit it and you walk in. Door closes behind you. When you leave, you can hit a button from the inside and get out. Mind blown, right? Anyway, thats the purpose of that! So, in the end, lever 1 flipped OFF and lever 2 flipped OFF will power your whatever OFF. If either are ON, then the whatever is ON. If both are on, then the whatever is ON.

AND Gate.

This gate is less common then the two previous ones, and it's basically the opposite of the OR. The AND, as the name suggests, mean lever 1 and lever 2 both have to be ON in order for you whatever to be ON. A good use for this is on a order-insensitive (you don't have to flip the levers in any order) combination lack, where you need lever 2 and lever 4 (out of 4 levers, or whatever you want) in order to open your whatever. To sum up, if only lever 1 is ON, then the whatever is OFF. If lever 1 and 2 are ON, the whatever is ON. If both are OFF, then the whatever is OFF.

NOR Gate

This is the opposite of the OR. I know, I know, I said that with the AND. But really, once you've read this, you'll understand. Really. Anway, the NOR Gate is also like an inverter plus an OR. When either lever is ON, the whatever is OFF. If both levers are ON, then the whatever is OFF. If both levers are OFF, then the input is ON. Does that make sense?
