Project #175
Project #174
Build the circuit shown and press the press switch (S2). It plays a
recording followed by one of three songs. Move the slider on the
adjustable resistor (RV) around to change the volume and for some
sound effects. You may press the press switch several times to play three
songs. The lamp is used to limit the current and will not light.
You can change the recorded message. Turn on the slide switch (S1),
you hear a beep signaling that you may begin recording. Talk into the
microphone (X1) up to 5 seconds, and then turn off the slide switch (it
also beeps after the 5 seconds expires).
Sliding Music
Turn on the slide switch (S1) and slowly move the lever on the adjustable
resistor (RV) until both the lamp (L4) and LED (D1) are flashing. They will
only flash together over a narrow range of the lever setting.
Replace the red LED (D1) with the whistle chip (WC) and readjust the
adjustable resistor until the whistle chip clicks and the lamp lights.
