For a halloween game i would like to build a flash light with countdown timer. It only lights and counts down when the button is pressed. The idea is that the user thinks about when the flash light is being used because when the time runs out they have to continue in the dark.
i have found code for a countdown timer that does this, but how can i make the led light up at the same time and, most importantly: how can i prevent the led from lighting up when the timer hits zero?
Any help is much appreciated!
