1) Created a QR code linking to a text message using QR Stuff.
2) Printed the code and determined the scale – how many Lego units did we need?
3) Built the QR code such that the code was a 21-by-21 square in Lego units
4) Crossed our fingers
5) Scanned the code using Qrafter… and it worked!
6) Went to the Lego store to buy a LOT more 1-by-1 Legos for future projects!
We have QR fever! 😉
