Circuit Description

Graph image for 555 Timer Voltage Controlled Oscillator

Circuit Graph

This circuit shows a basic voltage controlled oscillator based on the famous 555 timer. A voltage divider (10k potentiometer and 1k resistor) provides a user-settable voltage on the CON pin of the 555 timer. This controls the the frequency of the output oscillation.
