I am a web developer recently fell in love with raspberry pi.
I am trying to build a DIY re-freshable display like this: https://www.youtube.com/watch?v=fEX5iGqbS6Q where I want to display braille. However, I am struck. can some point me in the right direction?
Do I need a motor for each pin to move? If yes any link to suitable motors and articles?
Any information on how to do this is helpful. Thanks.
