-- this function does nothing until you write

-- It then checks the click position and turns the
-- lamp on if button one is clicked or turns the
-- lamp off if button two is clicked

-- OK. Now we need to check if a click happens
-- we will use a repeat-until loop.
-- In the loop we we use a os.pullEvent().
-- an os.pullEvent() gives you different info
-- depending on the event type. We will mainly
-- check the "monitor_touch" event.

-- In the second line you will see
-- event,p1,p2,p3 = os.pullEvent()
-- if the event is a click on the monitor it
-- will give us 4 bits of info:
--    event will be "monitor_touch"
--    p1 will be the side the monitor is on (top)
--    p2 is the width postion of the click
--    p3 is the height postition of the click



repeat
-- repeat runs a loop of code.

  event,p1,p2,p3 = os.pullEvent()
  -- this line tells the computer to wait until
  -- an event happens. We are waiting for a
  -- touchscreen event

   if event=="monitor_touch" and then
   -- this checks to see if the event was a
   -- touchscreen event

     mouseWidth = p2 -- sets mouseWidth
     mouseHeight = p3 -- and mouseHeight
     checkClickPosition() -- this runs our function
   end
   -- the end of the "if loop".


until event=="char" and p1==("x")
-- this is the end of the "repeat loop". This will
-- stop the repeat loop if a "char" event happens
-- A char event means you press a character on
-- the keyboard. This line is looking for the x key
