Braille printer for blind people

Description of Invention

The printer designed by us works on the principles as follows:
Inputs of the printer are texts or images. The software uses open source code OCR (Optical Character Recognition) technology to convert image files into texts. After that、 the software will convert characters into digits 0 1 corresponding to the Braille position of that character in the alphabet for blind people and transfer command to printer. Arduino Mega circuit will receive command from the software to control drive system and heat system of the printer to print Braille.
