A prototype for a refreshable Braille display using Raspberry Pi.
● The aim of this project is to convert text to Braille Display.
● It also speaks out characters as it displays.
● Can be used for educational purposes.
● I have implemented the prototype using LEDs, but Vibration motors can be used in their place.
➢ Raspberry Pi 2.0 B+
➢ Headphones
➢ Bread Board
➢ LED’s (6)
➢ Resistors (330 Ohm)
➢ LAN, USB
