  14. 14. Four  score  and  seven  years  ago  our  fathers  brought     forth  on  this  conHnent,  a  new  naHon,  conceived  in     Liberty,  and  dedicated  to  the  proposiHon     that  all  men  are  created  equal.  (200  leMers)  
  15. 15. With  the  above  QR   codes  printed  on   pieces  of  paper,  can   use  the  Scanner  app   on  iPhone  and  display   the  words  on  the  big   projector  screen,   using  this  adapter:   “this  is  how  the   computer  can  read  the   codes  from  a  piece  of   paper,  now  let’s  try  it   as  an  experiment   yourselves..”
