I don't really know how to code Lua, but I've been trying to make a program that sets off an alarm when the Arc Furnace runs out of electrodes.
I had several variations, but this was the closest I got .

arc = peripheral.wrap("left")
while
arc.hasElectrodes(false) do
redstone.setOutput("top",true)
end
if arc.hasElectrodes(true) then
redstone.setOutput("top", false)
end

I could get it to run, but it output a redstone signal even if there were electrodes in the furnace. If some of could help me that would be awesome.

You are on the right track. The error is the function hasElectrodes returns a bool. (true / false) Try it like this :

arc = peripheral.wrap( "left" )
redstone.setOutput( "top", false )
while arc.hasElectrodes( ) do
	sleep( 1 )
end
redstone.setOutput( "top", true )

I don't really know the api for arc furnaces so if you linked a page with the documentation i can help you better but if i had to take a guess the code should look like this.

arc = peripheral.wrap("left")
while true  do   --# will loop forever. Hold ctrl+ t to stop it
if arc.hasElectrodes() == false then
  redstone.setOutput("top",true)
end
if arc.hasElectrodes()== true then
   redstone.setOutput("top", false)
end
end

I have tested it and the function hasElectrodes only returns true when it has all three electrodes. Any less and it will return false.

snip of sourcecode from IE

case 6://hasElectrodes
   return new Object[]{te.electrodes[0] && te.electrodes[1] && te.electrodes[2]};

I think you need to use getElectrode.

A problem I found is that the alarm doesn't turn off when I put electrodes in

Something like this, you can modify, put it into a eternal loop, etc as you wish.

redstone.setOutput( "top", false )

furnace = peripheral.find( "IE:arcFurnace" )
repeat
  sleep( 1 ) --# dont overload the system
  nElectrodes = 3
  for nIndex = 1, 3 do
	if furnace.getElectrode( nIndex ).damage == nil then
	  nElectrodes = nElectrodes - 1
	end
  end
until nElectrodes == 0

redstone.setOutput( "top", true )

Because the code i posted ends at that point. You can do a eternal loop as Unknowntissue posted.

How would I implement that into your code?

[moTechPlz]

redstoneOutput = "top"
furnace = peripheral.find( "IE:arcFurnace" )
while true do
  nElectrodes = 3
  for nIndex = 1, 3 do
	if furnace.getElectrode( nIndex ).damage == nil then
	  nElectrodes = nElectrodes - 1
	end
  end
  if nElectrodes == 0 then redstone.setOutput( redstoneOutput, true )
  else redstone.setOutput( redstoneOutput, false ) end
  sleep( 1 )
end
