my ups beeps every 10 seconds when its runnin from battery. which is very annoyin. it then beeps every second once the battery starts to go low and its about to shut down. what i need is some sort of circuit that will sound a buzzer when it beeps every second, and for it to do nothing when it beeps every 10 seconds. any have a schematic or any idea how i can do this?
