Whenever a switch is pressed, a popular tone plays and refresh our mind. When next time when switch will press  a new tone will produced.Using the circuit we have prepared here 12 different tones can be heard in sequence.and then it circuit is 12 tone doorbell alarm circuit.

This is very simple project, it requires very less component and then its make it easy and simple but interesting project. Connects All components as given in circuit diagram . 1.5v to 4.5v DC supply required for operation of this multi tone generator circuit.

This circuit is based on ic UM34815A , Which is a 16 pin musical tone generator ic and this circuit is implemented as 12 tone generator.
