Need help with my program

[Turboclonerider 0]

I am trying to make a program that will output a redstone signal to a light grey cable (from project red) so i can get enhanced portals 3 to activate a portal, but i can't get the redstone to work and i prefer using the computer. (uploading screenshots wouldn't work)

 

error:

 

/home/initialization:4: attempt to index field 'redstone' (a nil value):

stack traceback:

            /home/initialization:4: in main chunk

            [C]: in function 'xpcall'

            machine:751: in function 'xpcall'

             /lib/process.lua:78: in function </lib/process.lua:71>

stack traceback:

             [C]: in function 'error'

             /lib/process.lua:92: in function </libprocess.lua:71>

 

 

 

the code:

 

local component = require ("component")

local component = require ("sides")

 

component.redstone.setOutput(sides.back, colors.lightGrey, 16)

print("Event Initialized")

well you assigned the component to the correct thing to start then you reassigned it to the sides api.  

 

Try this instead, also put the code into the code quotes. there is a button  for  it that looks like this <> it makes code stand out like code.

local component = require "component"
local sides = require "sides"
local color = require "color"

--for fun lets use a variable for the Redstone card too

local redstone = component.redstone

--oh and you need to use setBundledOutput from the tier 2 card

redstone.setBundledOutput(sides.back, color.lightGrey, 16)

print("Event Initialized")

Bear in mind, I didn't test any of this so it might not work, but it addresses the obvious issues.  Best of luck doing the thing
