Pressure Sensor Circuit using Colpitts Oscillator

This circuit we are using to run the pressure sensor with arduino. For controlling pressure sensor with arduino, we need frequency, so in order to obtain frequency from pressure sensor, we need to implement the colpitts oscillator circuit. While connecting to arduino, instead of Voltmeter, we will attach that point to pin 5 of arduino (PWM pin). https://en.wikipedia.org/wiki/Colpitts_oscillator
