 -- This is a comment. It's for humans only. All
 -- the green text is not run by the program
 
 mouseWidth = 0
 mouseHeight = 0
 -- this creates two variables called mouseWidth
 -- and mouseHeight and sets them to 0. We will
 -- use them later
 
 monitor = peripheral.wrap("left")
 -- you need this line! It tells the computer
 -- the monitor is on top. Change it if you want
 -- the monitor on a different side of the computer
 
 monitor.clear()
 -- this clears the monitor screen
 
 monitor.setCursorPos(1,1)
 -- this sets the cursor position to the top left
 -- corner of the monitor
 
 w,h=monitor.getSize()
 -- gets the width and the height of the monitor
 -- and stores the numbers as w and h.
 -- w and h are variables
 
 print(w)
 print(h)
 -- prints the w and h to the computer screen.
 -- You can see the monitor width is 7, height is 5
 -- It starts in the top left corner like a book.
 
 
 -- Now to draw the two buttons
 -- Im english so I write colour but you can change
 -- it to color. It works the same.
 
 
-monitor.setBackgroundColour((colours.green))
+monitor.setBackgroundColour((colours.red))
 -- this changes the background colour of the text
 -- to lime green.
 
-monitor.setCursorPos(2,4)
+monitor.setCursorPos(1.5,2)
 -- this sets the start position for writing the 1st
 -- button on the monitor. It puts it 2 in from the
 -- left and 2 down from the top.
 
 monitor.setTextColor(colors.black)
 monitor.write(" OPEN  ")
 -- this writes the word ON on the monitor. See the
 -- blank spaces before and after. These will be
 -- green. Our button is 5 letters long
-monitor.setCursorPos(2,5)
+monitor.setTextColor(colors.black)
 
 monitor.setCursorPos(1.5,4)
 -- this sets the next writing postition to 2 from
 -- the left and 4 down from the top. Just under
 -- the 1st button
 
 monitor.write(" CLOSE ")
 -- this writes OFF but again its 5 long in total
 -- with the spaces
 
 monitor.setBackgroundColour((colours.black))
 -- now we have drawn our buttons we should set
 -- the text background colour back to black
 monitor.setTextColor(colors.black)
 
 -- Now we need to check if the button is clicked
 
 -- First we are going to create a function called
 -- checkClickPosition(). A function will not run
 -- until you ask for it.
 
 -- We know the first button starts at 2 from the
 -- top and 2 from the left. We also know it is 5
 -- spaces long. This means the button ends
 -- at width 7
 
 -- We will be told which width and
 -- height the click happened at.
 -- If the width position is greater than 1 AND
 -- less than 8 we have clicked somewhere between
 -- 2 and 7.
 
 -- If this is true we can then check the height
 -- position. Button one is at height 2 and button
 -- two is at height 4.
 
 -- This means that if the width is greater than 1
 -- AND the width is less than 8 AND the height
 -- equals 2 we have clicked button 1
 
 -- If the the width is greater than 1 AND the width
 -- is less than 8 AND the height equals 4 we have
 -- clicked button 2
 
 -- now to write this as a function
 -- Functions are written like this
 
 --     function exampleFunction()
 --       print("Hello")
 --       sleep(10)
 --       print("Goodbye")
 --     end
 
 -- Now when you write exampleFunction() the program
 -- will print hello, sleep for 10 ticks and then
 -- print Goodbye.
 -- This is useful for making your programs easier
 -- to understand
 
 function checkClickPosition()
   if mouseWidth > 1 and mouseWidth < 8 and mouseHeight == 2 then
     -- button one clicked
     rs.setOutput("right",true)
 	sleep(3)
 	rs.setOutput("right",false)
     -- turns redstone connected to the right on
   elseif mouseWidth > 1 and mouseWidth < 8 and mouseHeight == 4 then
     -- button two clicked
     rs.setOutput("right",false)
     -- turns redstone connected to the left off
   end -- ends the if loop
 end -- ends the function
 
 -- this function does nothing until you write
 -- checkClickPostion(). We will be doing this below
 -- 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" 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
