Sethi Abstract - This paper presents an innovative microcontroller-based system designed to convert text files into Braille script, making Braille content more accessible for visually impaired users. The system leverages an ARM-based microcontroller and servo motors to enable real-time, mechanical translation of text into tactile Braille characters. To facilitate ease of use and to allow offline operation, an SD card is used as the primary storage medium for text files, enabling users to load and convert documents without requiring an internet connection or additional devices. This design emphasizes affordability, scalability, and usability, with the primary aim of making Braille conversion technology more accessible to educational institutions, libraries, and individuals, particularly in resource-limited settings. By reducing dependency on costly, proprietary Braille technology, this system can improve access to information and literacy among visually impaired communities, especially in developing countries where Braille materials are often scarce or prohibitively expensive. The paper thoroughly explores the system’s hardware and software components, detailing the architecture and function of each element within the overall design. A focus on energy efficiency is highlighted to extend the device’s operational time, and efforts to minimize manufacturing costs ensure this solution remains within a low-cost budget. These design choices make this Braille converter a sustainable option for broad deployment and adoption. Further development aims to expand the device's functionality by integrating wireless connectivity for text input, allowing users to access a greater range of content through online sources. Additionally, future iterations could support a larger tactile display, accommodating more Braille cells simultaneously, which would improve the reading experience for users and enhance the system’s application in educational environments.
