An IC which can produce three melodies. Requires only a 3V battery and a small 8Ω speaker (such as 35-0047 – see PA & audio/video section) to make a working project. By making connections to separate input pins each melody may be triggered individually. Additionally, an input pin is provided that will play all melodies in sequence. The tempo of the melody may be adjusted to play faster or slower by varying the value of Rosc resistor.
