Use the circuit from the Drawing Resistors project #516, but

connect the PC-interface cable across the speaker. Use a pencil to

draw the shapes shown in projects #516-518, as per the directions

given in those projects. Use Winscope to see how the waveforms

and frequency spectrums vary as you move the jumper wires

across the shapes to change the sounds. A sample is shown here.

Next, place the loose ends of the jumper wires into a cup of water, as

per project #519. The waveforms and frequency spectrum you see

will be similar to the resistors you drew, just as the sounds are similar.

Project #PC66

Drawing Resistors PC

OBJECTIVE: To draw your own resistors.

Settings

Build the circuit and try the settings shown. Flip on the slide switch

and press the press switch a few times while moving the

adjustable resistor control around. View the waveform and

frequency spectrum.

Project #PC67

Electronic Noisemaker PC

OBJECTIVE: To view the output of an oscillator circuit.
