Making an Affordable, Refreshable, Modular Braille Display

We made an affordable and modular refreshable braille display for our senior design project (mechanical engineering). Using basic and cheap electromechanics, this project is accessible for the masses compared to the expensive and non modular options on the market. The software used for the design include: Fusion 360, KiCad, Python, Arduino IDE Some of the fusion 360 files to play around with https://www.mediafire.com/folder/e66w.... I used dowel pins from Mcmaster https://www.mcmaster.com/91595A953/
