Project #3: Voltage Controlled Oscillator (VCO)

1. Adjust the potentiometer. What happens to the sound frequency as R3 is adjusted?

It changes according to the position of the potentiometer.
2. Measure the voltage applied to pin 5. Adjust the pot to give the highest possible voltage.   4.7 volts
3. Now adjust the pot for the minimum voltage to pin 5. The voltage is 3.2 volts
4. The output frequency is highest when the control voltage at pin 5 is lowest.
