Whistling Recording IC
Build the circuit shown. Turn on
the slide switch (S1), you hear a
beep signaling that you may begin
recording. Talk into the micro-

also beeps after the 5 seconds
expires). Press the press switch

recording you made followed by
one of three songs. If you press
the press switch before the song
is over, music will stop. You may
press the press switch several
times to play all three songs.

Use the preceding circuit, but replace the 3-snap
at base grid locations E6-G6 with the speaker
(SP2) and place the red LED (D1) over the 100W
resistor (R1). It will be across base grid locations
A6-C6 on level 4, with its “+” side on top (at A6).
