PC JOYSTICK

.BTN1	Button A
.BTN2	Button B		
.BTN3	Button Trigger
.R2	100k 	X-axis variable resistor. Used for pitch.
.R6	100k	Y-axis variable resistor. Used for lowpass.

Integrated Circuits (ICs)

.IC1	40106	Hex Inverter IC. Jameco #1231601.
.U1	7805	5V Voltage Regulator. Jameco #876125.

Resistors & Capacitors

.R1	10k	These three resistors change the pitch.
.R3	180k	Smaller value => higher pitch.
.R4	5.6k	Higher value => lower pitch.

.R5	1k	Used for lowpass filter.

.C1	0.01uf	Used for lowpass filter.
.C2	0.1uf 	Determines pitch (smaller value => higher pitch).
.C3	1uf	Used as power smoother.	

OTHER

.J1	Audio Output (for example, 1/4 female audio jack)
