## Versatile LED matrix dice machine

Rolling dice is a common way of generating random numbers for many board games. I think it is always more fun to roll real physical dice to get number for next turn. It is practically true random number as physical world always brings some entropy. Anyway there are other ways of getting random numbers. Walter has focused on building LED matrix dice – an Arduino based random generator. Having Arduino on board, he didn’t limit himself with just couple of dices. He also added a row of other randomness. He simulated such things as coin flip, various dice modes for different games like dungeons and dragons. Also his machine randomly shuffles cards where player can draw a card. Also it gives ability to generate HEX and bin numbers and lastly it can help generate passwords. After he put electronics in a portable box, it really became helpful gadget in many situations. Continue reading
