Well, it has correctly read the “giant” barcode printed on paper (A5 format), while
- gives back the wrong number reading a shoes box barcode
- doesn’t read at all the barcode printed on the cover of Learning Processing
I tried changing the light conditions especially for the book that has a shiny cover which probably makes it hard to be read; also tried to putting the objects closer of farther from the camera with no success.
I used my FaceTime camera - discovering that doesn’t autofocus the image; to overcome this issue, I tried to export the sketch to Android to test it with another camera, but the export failed - anyway, this is the chapter for another book
