Abstract

The aim of this project is to create a refreshable electronic braille display using Raspberry Pi 2 and Arduino Mega2560 board. This aims at creating a refreshable braille display that is capable of converting Normal text file as well as printed image files to braille. To achieve the functionality of converting image files to text we have used tesseract-ocr engine of Google which the best available OCR engine available right now and is highly accurate. The Raspberry pi does the image processing and the Arduino drives the display. The display is made of 6 servo motors, which can be controlled by the PWM. The servo motor acts as an actuator in this project..

Keywords: Braille, OCR, servo motor, PWM, Arduino, Raspberry Pi
