    4x4 Keypad for Arduino with color keys and braille texture (no membrane buttons)

    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:
    Click image for larger version. 

Name:	keyboard.png

    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!

    Making your own keypad is fairly easy and you can buy Braille keypad stickers from Amazon and others. You could consider these: https://www.amazon.co.uk/Tutoy-Multi...15091691&psc=1 or salvaging keycaps from a cheap keyboard, for example:https://cpc.farnell.com/unbranded/bc...yABEgINOfD_BwE
    It probably doesn't matter what is actually printed on the key if you are covering it over anyway.
