Abstract: The estimated number of people visually impaired in the world is 285 million, 39 million blind and 246 million having low vision. These people face many issues in accessing the text which is not in Braille script. Here we are proposing a prototype to help those blind people which convert text in the image to braille code. A camera is used to capture the image, the captured image will be processed by image processing techniques and the same will be converted to text using Matlab. The detected text will be transferred to Arduino through serial communication. The Arduino will be programmed in such a way that, it recognizes each and every character and converts it to braille code using the servo motor. The motors will be placed in 3 x 2 array of the matrix representing braille code. The servo arms will protrude out for its corresponding letter by rotating it in 90 degrees which depicts the particular alphabet. Hence it provides the tactile sensation of braille dot and visually impaired people will be able to read
