Hi, Which solution can someone suggest to detect that a book is open or closed ? For a specific page ? and better to detect the page opened ? just a switch, weight measurement ???? I'm a bit new about arduino and sensor... Sebastien

Opening a book

300 dpi is enough for OCR of printed text that is not too "distorted" (vague isn't it)

at 600 dpi one can discriminate between fonts a bit easier.
