Melody begins ic um66 the first note if power is reseted. It can also be easily interfaced with a normal Piezo electric speaker even buzzer or to a ic um66 ohm speaker through a NPN transistor as shown below. This will maintain output voltage nearer to 3. Thus an NPN transistor is used for amplification.
