is an innovative electronic braille device that interfaced to a PC to allow visually impaired to type text and read braille characters embossed dynamically on the device’s “display”.
The prototype that won several awards, is based on Arduino 2009 and a LED matrix that emulate the mini actuators embossing matrix.
It’s a very good way to know more about braille and how to use arduino’s port registers for real time tasks.
We will upload the blog with future prototypes and events.
The design and the new method for embossing braille characters on a polymer sheet has been patented by Nial Slater, the invetor.
