dougp:
I think, you meant was:

Another approach: Use two switches to generate the count up and count down signals. Use a third switch to progressively cycle through which digit the count switches act upon.

Based on your graphic the switches are virtual. True?

however you wanna read/interpet it.. and i am using an arduino mega with real buttons.. that image was from a game made for the nintendo ds created by a friend and i'm trying to re-create it with the arduino..

UKHeliBob:
Use arrays and a for loop to avoid repeating code

i never said i was a great coder... i'm still new to arduino - i just gave up for awhile and now i wanna try to accomplish some old projects..

evanmars:
Why is your code so super secret?

it's not.. just i code like a beginner

right now i'm just testing a code.. it works, but it could be better and shorter... i just dunno how
