Project #308
Project #309

Playing Music

OBJECTIVE: To play the three built-in
songs on the recording IC.
Use the circuit in project 308. Turn on the
switch (S1), then press the switch (S2) to start
the first song. When the music stops, press
the switch (S2) again to hear the second
song. When the second song stops, press the
switch (S2) again, the third song plays.
-9-
OBJECTIVE: To demonstrate the capabilities of the
recording integrated circuit.
Build the circuit shown. Turn on the switch (S1), you hear a beep
signaling that you may begin recording. Talk into the microphone (X1)
up to 8 seconds, and then turn off the switch (S1) (it also beeps after
the 8 seconds expires).
Press the switch S2 for playback. It plays the recording you made
followed by one of three songs. If you press the switch (S2) before the
song is over, music will stop. You may press the switch (S2) several
times to play all three songs.
Project #310
Light-
Controlled
Music
OBJECTIVE: To build circuit that uses light
to control the recording IC.
Use the circuit in project 308. Replace the
switch (S2) with the photo resistor (RP), then
turn on the switch (S1). Turn the music on and
off by waving your hand over photo resistor.

Project #311
Touch-
Controlled
OBJECTIVE: To build circuit that lets you
control the recording IC with your fingers.
Use the circuit in project 308. Replace the
switch (S2) with the PNP transistor (Q1) and
then turn on the switch (S1). Turn the music
on and off by touching the base and collector
at the same time. You may need to wet your
fingers.
