I need a timer that will begin counting when a button is pushed (the countdown must be uninteruptable even if the button is pushed again during the countdown), I need it to be programmable or have a switch that will preset the countdown to one of three different times, I need a display that will show the countdown, and when the countdown reaches zero, I need it to light a small light. Once the light is lighted, I need the button to restart the sequence again.
All of this will be battery operated.
Any info would be appreciated.
