When I am trying to verify the code, it is saying that QRCode is not declared in the scope. Please help me : (

Dear Mario, how many textcharacters can be 'hidden' in the message that creates the QR-code?

[@marios_ideas]

I have not tested it from that perspective. But if add more characters at some point the code becomes bigger then 29x29. But this is for representing short texts like serial numbers, urls
