[CC] Name assignment via redstone strength

local function sendID(ID) -- ID is a number which is tracked outside of this function, it should always be between 1 and 15
  redstone.setAnalogOutput("front", ID) -- turn on redstone
  repeat
    print("waiting for confirmation")
    os.pullEvent("redstone")
  until redstone.getInput("front") -- this works directly against the turtle but not if there is redstone
  redstone.setAnalogOutput("front", 0) -- turn off redstone
end

local function reciveID()
  while redstone.getAnalogInput("back") == 0 do -- if no signal then wait for one
    os.pullEvent("redstone")
  end
  os.setComputerLabel("T"..tostring(redstone.getAnalogInput("back"))) -- signal strength is our number
  redstone.setOutput("back", true) -- send confirmation signal
  while redstone.getAnalogInput("back") ~= 0 do -- if the ID signal is still there then they haven't seen our confirmation yet
    os.pullEvent("redstone")  -- when the ID signal is gone then they have seen our confirmation
  end
  redstone.setOutput("back", false) -- turn off confirmation signal
end
