Abstract
Braille is a tactile system that allows blind and partially sighted people to learn to read and
write. Braille enables the blind and visually impaired to learn spelling, grammar, and
punctuation and to comprehend the formatting of text on a page. Different people learn in
different ways; some might find it easier to hear material aloud, while others would prefer to
read Braille. The advantages of being able to read in Braille, however, exceed audio versions
when it comes to truly engaging with a book, particularly complicated written material, as
reading enhances comprehension and memory retention. Using Braille can help someone
improve their writing and self-expression abilities. This study focuses on a device that will help
users learn Braille in an easier way; in every bump made by the user to the Tilt Sensor, the
microcontroller will read its matching output, and it will be displayed in the LCD and Speaker
for the benefit of the User and Guardian.

A correlation with the survey's results was developed by the output evaluation. Prototypes of
products are extremely useful and effective. In addition, the specified Targeted customer's
opinion of the suggested product prototype is aggressive since most of the weighted average
of every sign indicates a value higher than 3, which on the Likert scale indicates agreement
demonstrates that the intended client's opinion of the product's prototype is belligerent.

After the prototype's testing, the Arduino utilized technologies that were compatible with one
another. The analysis supports the main conclusions evidence that the Braille to Text and
Speech Learning Tool for the Blind. The control system used Arduino Uno as a microcontroller
with the Tilt Sensor, which was effective to use as a learning tool and operational.
