In an effort to produce a led random selection project (I am trying to make a selection device that will randomly select the starting weight class for high school wrestling matches) I have found a possible solution by modifying a basic roulette wheel type game. The question I have is; can I modify the roulette wheel to select only 14 or 18 weights (leds) as apposed to the 36 leds that the project typically is designed with? Any other suggested routes for this project would be appreciated.
