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)

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..”
