To start off, yes this is actual code that you can run a CC computer, the script is set to talk with the gate reader that you put next to it, and that gate reader can give you all the options the regular pipe gates can.
To copy a code into a turtle, you have to use a printer, or wireless, sadly copy pasting doesn't work to great, not for me at least.
The gate reader is supposed to read data gates normally would do, like gates on a tank valve, it detects fluid level.
Now if i were to put a gate reader there and a computer next to it, I could tell it to do something when e.g Full Power, No Power, Space in inventory, Is working, etc, is triggering something further in my code, like turn off green wire and blink x times on red wire. Which again maybe is connected to the lights, turning of the green wire made a blackout, but the pulsing on the red wire started your backup generator.
This scenario could be used if you put a gate reader next to an MFSU, and the computer hooked to that could get those data rapidly, and if lets say the MFSU must NEVER run out, that means meltdown in your reactor! uh oh! So what you do then, if you want to make an alarm system out of it using computers, you could write a program that read the Is Full flag, and when that turns false, you know the MFSU is draining, and in your system that means failure! So, luckily you have set up you gate reader next to your MFSU and hooked a computer to that. Now your running program detects a change in one of the values, and turns of the green wire, it also starts blinking on the red wire.
Now what can I with those wires now that I have my bulky, yet cool and flexible alarm system... Lets set red wire to some well placed red lights, dimmer than your regular lights, the green wire turns of the lights, and disables your biggest machines, as well as setting off a howler alarm!
Now you have a "dead" factory, its dark, and there is red light everywhere, the alarms chimes and there is absolute havok.
Luckily your nuclear technician is online, so inside all this chaos, he brave goes down into the reactor chamber and inerts the fuel.
He walks up like a hero, but everyone was hiding in the end, being eaten by the ender dragon!
So if you could follow that then you agree that Gate Readers ate your friends,
