Hello.

How can I design a keypad matrix 4x4 for Arduino with the capability to custom the color and icon/letters keys and braille texture?

Example:

At the moment, I only have the idea to buy a keyboard with standard buttons and in the other hand buy the buttons with different colors and a plastic protector for each key. After it, print a sticker for the keys and in the plastic protector put the texture of the letters in braille.

Thanks!
