would like to build a push button timer. push the button the timer is set for 17 min then alarm goes off. also the timer must be able to add 1-2 minutes and subtract 1-2 minutes if desired.
push button again to turn off alarm. (nothing more than the simplist alarm clock that turns on when pushed and off when pushed ) please help
