There's a bunch of doorbell circuits here: The nice thing about the 4026 in the circuit is that it is a counter and 7 segment display in 1 chip. You could use a 4017 and 10 LEDs where each LED represents a number from 0 through 9. Ed

)of a doorbell with a counter. But it uses a HT 2811 chip for producing the door bell sound-unfortunately couldn't find it- does anyone know of any easily available alternative?

Also, does anyone know of anyone of any other counter other than 4026??
