In this paper, the authors describe about designing and developing a system for controlling piezoelectric Braille cell by using Programmable Interface Controller (PIC) microcontroller. For this purpose, PIC microcontroller is used as a controller to the system for controlling the piezoelectric Braille cell. Piezoelectric Braille cells are used in many refreshable Braille display applications. The Braille displays using piezoelectric Braille cell are able to refresh the Braille character that are read by the visually impaired by touching the dots at Braille cell.
