Numbers of Visually impaired persons are suffering a lot for communicating their thoughts. Braille literacy is not affordable to all since the printers are expensive which costs roughly one Lakhs. This work aims to develop a braille embosser for the affordable price which embosses the A4 size sheet with braille code. Arduino Uno controller is employed to control the angular position of the stepper motor. The input is given as text format to the serial monitor of the arduino IDE. The input texts are converted into Unicode in order to get the corresponding braille code. With the help of stepper motors code is printed on the paper. Keywords: Braille Printer, Arduino UNO, Braille code, Stepper motors, affordable cost.
