  i dont know why but my code doesnt work as expected...
  when the minutes are for example 15, the led on pin 8 should light up..
  here is my code:
*/

#include <LiquidCrystal.h>

/*

  LCD type below (16*2)



      0A-1A-2A-3A-4A-5A-6A-7A-8A-9A-10A-11A-12A-13A-14A-15A
      0B-1B-2B-3B-4B-5B-6B-7B-8B-9B-10B-11B-12B-13B-14B-15B


  A = row #0
  B = row #1

*/
