Electronic Circuits - Voltage Controlled Oscillator Using 555 Timer

This electronics video tutorial explains how to create a voltage controlled oscillator using the 555 Timer IC. The control voltage pin or pin 5 is used to control the frequency of the output rectangular wave. As the voltage at pin 5 increases, the output frequency decreases. You can use a voltage divider network or a potentiometer to adjust the voltage at pin 5.
