Looking to make a simple LED scoreboard?
Looking to make a simple LED scoreboard for scoring "Bags" games (Cornhole). All i Need is 2 rows of 21 LEDS on each side of a vertical board with the bottom denoting scoring "1" and the top as "21". And I'd like to have some sort of momentary button to press that would move the circuit from 1 to 21 one increment at a time (moving up, turning on the next as the last one turns off). I could just put switches on each led but I am trying to avoid that. Any advise would be helpful. Thanks
PS , if all the lights stay on until i get to the top and then able to reset it, that would be fine too, Just trying to eleviate the use of multiple toggle switches.
