What are the possible uses of logic gates?

[Moist Potato]

So being able to open and close doors with 2 switches is obvious but what else? Maybe an elevator? (Although I cant think of how that would work, im very new to this game).

I don't consider my self an expert in logic but I have found the best way to learn about it is to just play with it.

Logic gates are contingency manipulators.
If this happens then this trigger will or will not be active-
but just explaining it here can be very confusing, when you play with it, you will understand it better.

Make a logic gate your friend call him Logie and see what happens when you connect him to different things and set things at different settings and route things in different ways.

You can also set your Logic gate to behave a few different ways explore those options as well while you're playing with your logic gate.

I was a beginner with logic systems not too long ago when I made up my mind that I wanted to build a cargo pod that would launch and deliver from one corner of the map to the other precisely all at the flip of one switch.

By not giving up and constant experimentation I built a type of "timer sequencer" that allowed me to tweak traditional timers until I got this.

Good luck on your logic adventures
