HK66T-08 Melody Chip plays ‘Happy Birthday’ continuously after connecting it to a 3-4.5V supply voltage.
After connecting to the supply voltage, it always starts with the 1st note.
The HK66T series melody chips can drive a piezo speaker directly, or a dynamic speaker using a transistor. Please see the datasheet for the connections.
Typical applications are door bells, alarm clocks or greeting cards.
We offer the HK66T with 4 different melodies:
HK66T-08 “Happy Birthday”
HK66T-11 “Love Me Tender”
HK66T-19 “Für Elise”
HK66T-OA “Jingle Bells”
You can check the sound samples before you buy to make sure you like the melody.
