Project 225 Your Music with Echo and Light
MP3 player
This circuit is similar to the preceding one, except
it adds light and has lower sound volume. Build the
circuit, and turn on the slide switch (S1). Connect
a music device (not included) to the audio jack (JA)
as shown, and start music on it. Set the knob on
the 500kW adjustable resistor (RV3) all the way to
the left (for loudest sound).
Set the volume control on your music device for a
comfortable sound level, and adjust the amount of
echo using the lever on the adjustable resistor
(RV). Try this at different RV settings. The color
LED (D8) will light when the sound is loud enough.
Try with different music, or with the touch-tones on
your cell phone.

Set the volume control on your music device for a
comfortable sound level, and adjust the amount of echo
using the lever on the adjustable resistor (RV); move the
lever up for more echo or down for less echo. Try this at
different RV settings, because the effects are very
interesting with both high and low echo amounts.
