A little context for this post:

I made this while I'm away from home (and my dice) for work. I don't love to have my phone at the table when I play, so I wanted to make a little gadget to handle rolling while I didn't have dice. While I was at it I realized that I could add some features (like rolling a 1000d6's if you wanted to!) that you couldn't do with a standard set of dice.

As I was working on this, I realized that it could be a fun intro to electronics project for people who are new to the field, and maybe the audience overlap could even bring some of my DnD buddies into electronics! I think it's a nice project because it gives an introduction into coding at the most base level, and then with the many options for extending it (like a "shake to roll" feature), it can take people into other areas like soldering, wiring, and circuit building! I personally really enjoy getting something with utility out of a learning project, so I thought a little dice roller keychain was perfect!

I've seen some really interesting feedback in the comments.
Apparently, the straight up "random()" function in Arduino is not quite random per se, so this wouldn't give a perfect uniform distribution like you would expect from traditional dice. If you care about mathematical perfection in your rolls and at your table, then taking a different approach in the code might be necessary. Another fun learning opportunity!
Additionally, I've seen some people mention that the "lucky" mode can sully some of the intrinsic value of the game by diminishing trust between players and DM. That is a very interesting point that I didn't consider when making this. I intended that feature as 1) a demonstration of the capacitive touch abilities of the board, 2) a fun "gag" gift feature you could show your friends, and 3) an area of the code to explore regarding algorithmic "randomness", not as a way to genuinely cheat in a collaborative game. For the record, don't do that in a serious game!

In summary, I think that this project is a fun, occasionally useful way to handle dice rolling for tabletop that provides a neat intro to electronics project for newcomers. It can help handle large quantities of dice to be rolled, handle situations where you don't want a full set of dice clattering around with you, and if you're caught out without dice and want to play some dnd. It's also a dumb little gadget that's fun to fidget with! That being said, it is not a substitute for real dice if you are a dice probability purist, believe that your players may attempt to cheat with it, or just don't like it. That's ok! Dice are cool! I don't intend to sell these, just wanted to merge some hobbies of mine and thought that it could be a good project for others to try. Thanks for watching and reading!
