chip and continues with a series of delays
and flashes. The “CALL” feature is a great
way of performing the same function over
and over. You simply call the procedure
you want; at the end of the procedure,
you place a return and it will go back to
the command after the CALL.”

Use either a small 16 ohm speaker or
(better yet) plug your stereo into the jack.
Set all the DIP switches to open. Put in
the batteries. Place R12 across the PIR
pins 1 and 3; short S2. The LEDs should
flash downward and then the voice chip
will activate. The LEDs will flash again. If
you leave S2 shorted, it will flash every
30 seconds. You can change the DIP
switches to increase the time. If you short
and release, it will flash each time you
short after the sound finishes at the time
level the DIP switches have been set to.
R12 prevents false triggering when using
A, it will change its outputs which you don’t want it to do.
So, you place port A into a TEMP register and AND the
TEMP registers instead.
Recording
Remove the PIR module. Connect a microphone or
tie the headers into the earphone
outlet of your computer and connect
it to the headers titled “MIC.” Put
one DIP switch in the closed position
and the other two in the open
position. When ready, short S2, open
S2, and short again to record. The
LED will light indicating that the chip
is recording. Wait until the light
turns off.
There are many thunder sounds
available on the Internet. Just perform
a search for “thunder sounds.” Use a
1/8” plug with about 6” of wire-wrap; put the plug into the ear
phone jack of your computer and
wrap the wire around the “Mic” pins.
Push both the play button on your
computer and short S2 at the same
time to record. The chip will record
10 seconds of sound. If you goof,
try again.
Happy spooking!! NV
