ComputerCraft: MiscPeripherals: 'Feed'

--v1.3 by GraySloth 2013-Feb-23 for the miscPeripheral mod with the Feeding Module it feeds animals between 6am and noon in-game time
--wheat carrot or seeds depending on the animal need to be in the only item in the turtle, and can only use one of those types of food at a time.
--it sends a redstone signal to output(bottom by default) if it can't find food, it can also be forced to feed manually if a redstone signal is sent to input(bottom by default) and can be set to always feed if alwaysOn is true

--variables
local feeder = peripheral.wrap("right")
--available locations: top, bottom, left, right, front or back
local input = "bottom" --receives signal for manual feeding
local output = "bottom" --sends signal when out of food
local alwaysOn = false --true sets to always feed
--functions
function clear()
   term.clear()
   term.setCursorPos(1,1)
end

function food()
   if turtle.getItemCount(1) == 0 then
      clear()
      print("Needs more food")
      print("Searching for food hold ctrl+t to stop")
      while turtle.getItemCount(1) == 0 do
         redstone.setOutput(output, true)

               turtle.select(n)
               turtle.transferTo(1)
        end
