i am workin on a clock drived by many servos, i will need 9 for the hours, 14 for the minuts ( 5 for the decimal digits and 9 for the others ) , and they will be 2 marks on every servo ( one at the 0 degree and one on the 45 degree ), so lets say the time is
"6:45" then 6 of the 9 servos ( for the hours ) will be on 45 Dg, while the others on 0 , and 4 of the 5 will be active ( for decimals ) and then 5 out of 9.

1 ) - i have problems setting time with buttons ... i cant figure out how to do it ?
2 ) - As you can see the case method will be quite long, is there another way to do it ? i was reading about arrays, but can anyone show me an example, because i am not sure how to do it neither.
