Spiller sangene: Jingle Bells, Rudolph the Red-nosed reindeer og Joy to the World.
In the circuit basically usability base IC UM66T use sound of music sweet-sounding origin and be usable easily. It use just integrated one circuit and a loudspeaker , piezo buzzer , the small-sized , and have power supply 3V only. The detail is other of integrated number this circuit.
The UM66T series are CMOS LSI designed for using in door bell, telephone and toy
application. It is an on-chip ROM programmed for musical performance. Produced by CMOS
technology, the device results in very low power consumption. Since the UTC UM66TXXL Melody generator IC series include oscillation circuits a compact melody module can be constructed with only a few additional components.
Part number Song name
UM66T-01L Jingle Bells + Santa Claus Is Coming To Town + We Wish You A Merry
UM66T-05L Home Sweet Home
UM66T-09L Wedding March (Mendelssohn)
UM66T-19L For Alice
UM66T-32L Coo Coo Waltz
UM66T-68L It Is A Small World
Most circuits, we find that the IC number UM66T common because the smaller ICI power consumption of culture is not very easy. Choose music that has many songs together.
Operation of the circuit when the power supply circuit are currents flowing through LED1 LED1 light and the electricity flowing into pin 2 of IC1 IC1 make music production work.
