VCO's are mainly found in synths they act as a core where all other waveforms can be derived from. The VCO output waveform is mainly controlled by the input voltage the project aims to create a saw tooth VCO and derive a sine wave from it 

The aim of this project is to design a driver circuit for an piezoelectric disk to atomize water into a mist as well as controls to adjust the output to a desired humidity. wireless nodes are used to take measurements which are then transmitted and averaged and fed back to the system
