[Lua][Question] A good Loop and Monitor

local sSide = "left" -- the side the monitor is on

-- check if monitor is present
if peripheral.isPresent(sSide) and peripheral.getType(sSide) == "monitor" then
  -- redirect terminal output to the monitor
  term.redirect(peripheral.wrap(sSide))
else
  -- no monitor, exit
  print("No monitor found")
  return
end

-- loop
while true do
  -- print here
  -- if you want to exit the program, use break to stop the loop
  -- wait for redstone change
  os.pullEvent("redstone")
end

-- restore terminal output
term.restore()

local monitorSide = "left" -- the side the monitor is on
local cableSide = "back" -- the side the bundled cable is on

-- check if monitor is present
if peripheral.isPresent(monitorSide) and peripheral.getType(monitorSide) == "monitor" then
  -- redirect terminal output to the monitor
  term.redirect(peripheral.wrap(monitorSide))
else
  -- no monitor, exit
  print("No monitor found")
  return
end

local function clear()
  term.clear()
  term.setCursorPos(1, 1)
end

-- loop
while true do
  -- clear screen
  clear()
  -- test each input
  write("MFSU#1: ")
  if rs.testBundledInput(cableSide, colors.red) then
	print("Empty")
  else
	print("Not Empty")
  end
  write("MFSU#2: ")
  if rs.testBundledInput(cableSide, colors.green) then
	print("Full")
  else
	print("Not Full")
  end
  -- wait for redstone change
  os.pullEvent("redstone")
end

-- restore terminal output
term.restore()
