I'm trying to create a little electronic box that I can sit next to me when I'm playing to calculate probabilities. Say I have a Heavy Crossbow and a Longbow plus 1. Which one has a better chance of beating an Ogre? I can do the math for the average in my head (sometimes, except when I'm tired, or there's red wine involved, etc.) but the calculator would be nice to have (OK, I admit, it's a fun side project with little actual value). My son also gets a kick out of seeing the exact percentages. Anyways, if I were a computer science guy I'd write an android app, but I'm not. I have figured out how to make the code work with the serial i/o of a consumer micro-controller (Arduino Uno, if you care).
What I need to know is this: by the end of RotR, what is the max number of dice and max plusses on any given check? I'm on the beginning of deck 3 now. I can purchase a numeric keypad and separate LCD screen, or I can get an integrated module with LCD and 5 buttons. If there are never more than 5 dice, or more than +5 to a check, 5 buttons will suffice. If there's more (which I suspect, as I already have +4 to a couple checks) I may need to be able to input integers. Hmm. I guess I could do a ranging option on the plusses. I'd like to minimize button presses, though if this is going to be quick enough to actually use.
Thanks.
