The Bookreader flips through the pages of a book, taking pictures of each page, and then turns each picture into a text document.
First, the bookreader prepares a page to turn by rotating a Lego motor. Gravity keeps just enough friction on the book page to inch the page forward. Next, a Lego arm beam swings around, forcing the page over.
After a new page is turned, the Raspberry Pi camera takes an image of the new page in JPEG format, and saves it to file. Using open source Optical Character Recognition software on the Raspberry Pi, the BrickPi turns the page image into text.
Finally, the Pi saves the text. Now we’ve digitized the page, and you have the start of your book. Just for fun, in our example we use some free text-to-speech software, and the Raspberry Pi reads the book out loud over some speakers we attached. Once the page is read and stored, the Raspberry Pi, through the BrickPi, turns to the next page of the book.
Each Friday is PiDay here at Adafruit! Be sure to check out our posts, tutorials and new Raspberry Pi related products. Adafruit has the largest and best selection of Raspberry Pi accessories and all the code & tutorials to get you up and running in no time!
8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
