A timer-controlled doorbell device has been developed using two 555 timer ICs in monostable mode, combined with a relay ...

The 555 timer is one of the most versatile integrated circuits available. It can generate PWM signals, tones, and single-shot pulses. You can even put one in a bi-stable mode similar to a flip flop.
