The system includes the digital control system board, the Braille display cells board and Braille display cells. The digital control system board integrates transmission interface, microcontroller, logic IC and function key. In this study, we use the transmission interface which has Bluetooth and USB to get the Braille signals. Then, the signals are transmitted through the microcontroller and logic ICs to Braille display cells. Besides that the function keys are used to control the display of Braille display cells. The Braille display cells board is the connection between the digital control system board and Braille display cells. It can be redesigned with different Braille display cells. The piezoelectric beams are used to drive the Braille display cells and make the Braille pod be carried easily. At the end, the control system is validated that the Braille signals can be transmitted through the Bluetooth dongle and the test software and display Brailles accurately.
