Build the circuit. Connect a music device (not
included) to the color organ (U22) as shown, and
start music on it. For best effects, place one of the
LED attachments over the light on the color
organ. Set the volume control on your music
device for best sound quality and light effects. The
color organ light will “dance” in synch with the
music. Compare fast and slow songs, and
different loudness levels.
