Project #PC20
Space War Flicker PC
OBJECTIVE: To continuously show the patterns created by the
space war IC.
Click on the On-Line button to activate, and turn on the switch
(snap part S1). Set Winscope to the settings shown below. The
signal from the alarm IC (snap part U2) causes the space war IC
(part U3) to step through the 8 different patterns it can create. A
sample waveform is shown here.
Settings Wait mode On-Line button
You can also activate Wait mode and press the On-Line button
several times to view one scan of the signal at a time, instead of
seeing continuous scans.
Turn on FFT mode to look at the frequency spectrum, try the
settings shown here. You can see the spectrums for the different
patterns produced by the space war IC, a sample is shown here.
Settings
Build the circuit shown. If continuing from the previous experiment
then close the Winscope program and run it again, to reset the
settings.
