valueReturns a QR code.
Renders a QR code from the input string: plain text when output="string" (default) or a data URI when output="dataurl". options.scale (1-20, default 4) and options.margin (0-10, default 4) are honored; out-of-range values silently keep the defaults. Empty input or a generation error outputs "" rather than failing.
A typical wiring for qr code: the value out pin feeds convert to uppercase.
