Braille cells and backpanels
Braille cells were developed to electronically display the Braille alphabet on any type of electronic device like computers or Braille display. Piezo actuators, which convert electrical energy to pin movements, were used in the structure of the Braille cell used in this study and it is shown in Figure 1. The pins replaced according to the character, sentence or paragraph that are send via the software developed.

If one wants to send more than one characters to the Braille cells, backplanes on which Braille cells in groups of 8 are mounted are used so that each Braille cell can be used actively at the same time. Backpanels may be used like 8, 6, 4 and 2. In this study, as 96 Braille cells are used, 12 backpanels with 8 Braille cells are used. The backpanels used are shown in Figure 2. The Braille cells mounted on the backpanels are shown in Figure 3.
