Project 34 Dance to the Music
Project 35 Super Dance to the Music
Build the circuit. Connect a
music device (not
included) to the color
organ (U22) as shown,
and start music on it.
Place one of the LED
attachments over the light
on the color organ. Set the
lever on the adjustable
resistor (RV), and 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.

This circuit is similar to the preceding one,
but louder and more sensitive. Build the
circuit as shown. Connect a music device
(not included) to the color organ (U22) as
shown, and start music on it, set the
volume to mid-range. Place one of the LED
attachments over the light on the color
organ. Turn on the switch (S1) and
SLOWLY ADJUST the lever on the
adjustable resistor (RV) for best sound;
there will only be a narrow range where the
sound is clear. Adjust the volume on your
music device for best sound quality.

Dance
to the
Music (II)
Use the preceding circuit,
but remove the 100
µ F
capacitor (C4). The sound
will not be as loud, but will
be less distorted. Adjust
RV and the volume on your
music deice for best
sound.

This circuit amplifies the
music so it can be heard
on the speaker. This is a
simple circuit, so sound
quality may not be as good
as your other music
players.
