Gangsir's mob farm controller
This program uses TankNut's interface program. Download at
https://github.com/OpenPrograms/MiscPrograms/blob/master/TankNut/interface.lua
If an internet card is present, the program will auto-fetch it.
To set up, connect a bundled redstone cable that OC supports to the computer,
and set colours on other ends to be as follows:
Red:Mob spawner
White:Lights
Orange:Door
Black:Killing Method
I recommend using some type of wireless redstone to avoid having to place cables everywhere.
