[How to] enable lights and disable lights with redpower2 bundle cable and computercraft

Dear Minecrafters,

Can someone help me plz.
Im stuck i have some idea's for a friend of mine who is the owner of WolfOS and i help him to make new stuff with it.
But the problem is i wanne use the redpower2 bundle cables and computercraft to give a choice menu and i know how that works,
but i don't know how to use the command.
example: to enable output color red and disable output color red and that yellow stays on

Plz help me all the help is welcome.

You need to use the colors api in conjunction with the rednet api. Here's an example

c = colors.combine ( c, colors.red )
rs.setBundledOutput("right", c ) -- turns red on

c = colors.combine ( c, colors.yellow )
rs.setBundledOutput("right", c ) -- turns on yellow leaving red on

c = colors.subtract( c, colors.red )
rs.setBundledOutput("right", c ) -- turns off red leaving yellow on

Type help redpower from the terminal for more information.

PS: here is the code

function Farm()
loop = true
tChoices = {}
tChoices[0] = "Turn Lights On"
tChoices[1] = "Turn Lights Off"
tChoices[2] = "Return"

tActions = {}

tActions[0] = function(TurnLightsOn)
term.clear()
term.setCursorPos(1,1)
print("Turning Lights On")
c = colors.combine ( c, colors.red )
rs.setBundledOutput("back", c ) – turns red on
sleep(2)
term.clear()
term.setCursorPos(1,1)
print("Lights are turned On")
sleep(1)
menuNum = 4
loop = false
end

tActions[1] = function(TurnLightsOff)
term.clear()
term.setCursorPos(1,1)
print("Turning Lights Off")
c = colors.subtract ( c, colors.red )
rs.setBundledOutput("back", c ) – turns off red leaving other colors on
sleep(2)
term.clear()
term.setCursorPos(1,1)
print("Lights are turned Off")
sleep(1)
menuNum = 4
loop = false
end

tActions[2] = function(Return)
menuNum = 2
loop = false
end

local nSelection = 0

while loop == true do
term.clear()
term.setCursorPos(1,1)
print(" Lixor " .. version)
print("")
print("Select an option:")
print("")

for nLine = 0, #tChoices do – Iterate through the possible potions, and print them, marking the chosen one
local sLine = "-"
if nSelection == nLine then
sLine = ">"
end
local sLineNum = tostring(nLine)
if #sLineNum < 2 then
sLineNum = "0" .. sLineNum – Prepend a 0 if it's too short
end
sLine = sLine .. tChoices[nLine] – Construct the string we're printing
print(sLine) – Print it
end

local sEvent, nKey = os.pullEvent("key")

if nKey == 200 then
if tChoices[nSelection - 1] then
nSelection = nSelection - 1
end
elseif nKey == 208 then
if tChoices[nSelection + 1] then
nSelection = nSelection + 1
end
elseif nKey == 28 then
if tActions[nSelection] then
tActions[nSelection]()
end
end
end
return

Try adding this to the top. There is another way to do it but I cant remember it off the top of my head

c = colors.combine ( c )

colors.combine() returns 0 if you don't give it any arguments, and when you do c = colors.combine( c), c is nil (isn't defined yet), so you give no params to the function.
Also, try to use local variables, globals can mess programs. If some program creates a variable named c with some color values, then you are setting that value to your variable also, getting unexpected results.
Example:
Program 1:

c = 0 -- set c to 0
-- some code
c = colors.combine(c, colors.red) -- add color red to c
-- exit the program

Your program:

c = colors.combine(c) -- set c to c (wich is red because of the other program)
-- some code
rs.setBundledOutput("side", c) -- red is on, if you don't wanted this to happen, there might be a problem
