These changes are used by the team's Co. Es via software to detect: if there is metal being detected or not & the size of the metal being detected. Small, medium, or large.

This portion of the circuit is the Colpitts Oscillator. As metal moves through the magnetic field of the inductor, the amplitude and frequency of the output of the oscillator changes.

This is the voltage regulator I designed for the Collpitts Oscillator. The oscillator requires ~2.5 V to operate. This circuit takes the available 3.3 V from the Basys Board and drops it to 2.7V. This is an acceptable value.

These voltmeters are for simulation purposes only. Thus, I added a property to exclude them from them (and Ground) from the PCB.
