Project 389 Light Dance Audio Override
Project 390 Light Dance Light Override
Build the circuit, which is similar to project 35 (Dance
to the Music). 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.
For the next part, you need the color organ light to be
changing slowly. Set your music device to play a song
with a slow beat, and set the volume control on it so
the sound is not too loud or too soft.
Now blow on the microphone (X1) or talk loud directly
into it. The dancing light pattern should be interrupted
by your blowing/talking. If you don’t notice any
difference then lower the volume control on your music
device. Songs with a slower beat work best for this.

Cover the phototransistor (Q4) with your hand
and 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.
Uncover the phototransistor and shine a bright
light on it. The color organ light will stop changing
until you re-cover the phototransistor. The music
will not be affected.
