Need an oscillator whose output frequency is adjustable with a voltage? Then look no further as this kit will let you build a voltage controlled oscillator!
The Voltage Controlled Oscillator is a very practical circuit for generating square and sine waves. While these waves can be produced using the Simple Function Generator Kit, the VCO allows for controlling the output frequency with the use of a voltage signal instead of using a potentiometer. This means that the output frequency of the VCO can easily be controlled by microcontrollers and other analogue circuits which can create some pretty interesting results. This kit is ideal for those learning about oscillator circuits, common applications include synthesizers, function generators, matched square/triangle waveforms, switch-mode power supplies, and PWM generators.
