I am planning to do a project on braille cells which will have basic functionalities.
For example, instead of number display watch (which already exist actually) why not to do analog display watch. This is just an idea if I can do some basic things I will elaborate later and then do something which will have a social value.
My questions are:
- Is there any project already done with Braille cells and Arduino (or even Ras Pi)?
- Where can I buy Braille cell compatible with Arduino?
Thanks in advance.
