Guys i need a 2 digit or 3 digit(7-segment) down counter circuit.It must start counting when triggered and activate the output(relay,buzzer,LED)as soon the count reach zero.Must have minutes and seconds selector switch.Functions almost like egg timer.Anybody have idea?

 

This sounds like a homework assignment for a class/course. Is it?
