What would I need to program this so that the LEDs will go up to 3/2 then back down to 0?
Well, it's actually more complicated that that, the balls and strikes would have to reset each other, and possibly increment the outs as well. If you did that, you would need fewer channels of remote.
With the 8-channel (7 used) you would simply turn each light on / off with a separate button, no logic need except in the brain of the operator.
To fully implement the logic of balls / strikes / outs a microcontroller would be best. Then you would need only 3 buttons:
1. A ball button would up the balls, and if 4 would reset balls and strikes to zero.
2. A strike button would up the strikes and if 3 would reset the balls and strikes and up the outs.
3. An out button (for any out other than strikeout) would up the outs, reset the balls and strikes and reset the outs if it reached 3. You could also do something cool like flash the ball / strike / out indicators a couple of times when there was a walk / strikeout / side retired. All of this is simple with a microcontroller, not so simple with discrete logic.
