3) R2 is the resistor with the color code: Brown, Black, Red. This comes in a package of ten, but

you will only need one. Keep the rest for future use.

4) Each potentiometer is marked with the values "5k" for R4, or "1M" for R1 and R3. Although

these potentiometers have their own spots on the board, you will be mounting them on the

enclosure, so solder a piece of hookup wire from the pad to the potentiometer, making sure

there is enough length wire between the board and your mounting area.

5) The toggle switch S1 has 2 pins which should be inserted into the board through the center

pad and the square pad. Do not place the switch through the pad without a trace.

6) The battery snap has two leads, each colored red or black. Solder the red lead to the positive

pad, and the black lead to the negative pad.

7) Solder the IC socket with the correct orientation onto the board. Keep note of the notch on

one end, (Figure 2). Insert the IC into the IC socket staying consistent with the notch.

8) You now have all your components sorted out, and it's time to find your ideal mounting

locations on the enclosure. Be sure to leave enough wire to comfortably reach each mounting

location. Make holes for the toggle switch S1, three potentiometers R1, R3, and R4, as well

as the PCB and the speaker, if desired. Refer to their respective datasheets for mounting hole

sizes.

9) Use the mounting hardware kit to mount the PCB and speaker. The potentiometers and

toggle switch already have nuts and washers attached.

10) After tightening all the screws and nuts, place the rubber feet on the bottom of the enclosure

on each corner. This will keep the enclosure from moving around and wobbling.

Testing the Circuit

Before making finishing touches and placing the lid on the enclosure, turn on the switch and make

sure the circuit works. R1 and R3 control the frequency and duration of the pulses, where R4 acts as

volume control. When the speaker is emitting a tone, you're ready to experiment.
