2. I put this into my scratch so that when the green flag was clicked to start the game, and wait an amount of seconds before the QR changes.

3. I have put this onto my first sprite one so then when you start the scratch game (by clicking on the green flag) my first sprite will say ‘Hello I’m going to show you some QR readers’ for five seconds then move onto the next bit in the order, which in this case is wait for two seconds before saying the next bit in the order and shows for you to scan the QR code with a IPhone, IPad etc.
