The circuit as shown in Figure below presents a 555 as an extremely simple, voltage-controlled oscillator (VCO). The VCO’s output frequency (U1) differs contrariwise with the input voltage. Using a 1 V input, the oscillator’s output frequency is around 1500 Hz. If you supply a 5-V input, the oscillator’s output frequency dips to about 300 Hz.

A voltage controlled oscillator is a rather simple device in theory—it’s simply an oscillator whose frequency is related to a control voltage. In other “words”: vco( ) vco C dθ t ω fv dt == Thus, if control voltage v C is a constant with respect to time, the oscillator frequency will likewise be a constant—the oscillator will produce a “pure” tone of the form: v
