Project:Bloodbowl Scoreboard

An arduino-controlled scoreboard for the board game Blood Bowl.

Proposed Features

• Scoring for each team.
  • Single digit should suffice for each team - either a small array of LEDs or (better still) a revolving scorewheel?
  • Audible touchdown celebration?

• Turn timer (each turn is 4-minutes long)
  • Perhaps a long row of LEDs that fills up from left to right for one player, right to left for the other?
  • Audible warning as time runs short?
  • Pause button?

• Turn counter
  • Needs to be able to be adjusted for pitch invasion kick-off table result.

• Re-roll counter for each team?

Chassis

• Should contain the reserves/K.O./dead & injured boxes for each team down the front.

• 24/48 LEDs in a long row above this for the turn timer.

• Above the LEDs, a score counter on each side and a speaker or central display in the middle.
  • Central display could act as turn counter? Got an 8x8 R/G LED array that might work...

• Big, very sturdy button on top to be thwacked at the change of turn.

Progress

• I have a working 24-LED turn counter on a test board, interruptable by a button, but it uses a pin for each LED - this needs to be reduced greatly, probably using shift registers (and/or conceivably charlieplexing)

Pin Count / Components

• Input
  • 1 - big red button
  • 2 - turn up & turn down buttons
  • 2 - P1 & P2 score button
  • 2 - P1 & P2 reroll buttons

• Output (lower pin reqs with shift registers)
  • P1 & P2 score - 2 x 7-segment display?
  • 48-LED turn counter - 3 x 16-channel LED driver?
  • P1 & P2 reroll counters: 16 x LED or 2 x 7-segment display?
  • Turn counter - 8x8 LED array?

Total available digital pins on a Uno: 14 (note: can use analog pins for digital output also!)

• 1 x Analog for speaker.
