Project #340
OBJECTIVE: See and hear the output of the music IC.
Set the meter (M2) to the LOW (or 10mA) setting. In this circuit, the
output of the music IC (U1) is applied to the less windings side of the
transformer (T1), which lights the LED (D1) and deflects the meter.
Place the adjustable resistor (RV) to the bottom position and turn on
the switch (S1). Adjust the adjustable resistor upwards. This
increases the voltage across the LED and meter. The LED brightens
and the meter deflects more towards 10. Place the speaker (SP)
across points A & B and use a jumper wire to complete the connection.
Now you can hear and see the output of the music IC.
