Education is the key to success in life, normal children learn from teachers in schools seeing and communicating with each other. For Visually challenged students learning to read and write is much more difficult because of visual impairment. The teaching aids required to teach such blind pupil are special and require lot of teacher?s attention. For a first time learning blind student, character set and numbers are taught with a help of marbles and slotted slate. Different arrangement patterns of marbles on slotted slate represent different characters. For each character representation, teacher has to reach each student and change the arrangement of marbles. This is harder and time-consuming exercise. This paper describes a Raspberry Pi based Hardware Implementation of the Braille teaching device, where the above problem can be abridged. This project implements a Braille Script Teaching Aid in which the presence of marbles is detected using IR sensors and this information is given to Raspberry Pi which produces the audio output of the letter. This method provides an easy way of teaching Braille Script. Some self-learning programmes are developed to make students to learn without the help of a teacher. It is well suited for first time learners. We can teach different languages with the same setup by selecting the language based on the requirement
