The code used to run the capacitance sensor on the Arduino was not of our own design, as capacitance sensing is a common task for Arduinos. We used starter code from the Arduino website, which we edited slightly to meet our needs. The first major edit was using pulse width modulation to visualize the capacitance with a single green LED. This was original to give an idea of when the capacitor was being overloaded and proved to be a fairly useful tool for testing. The circuit with the LED is included in Fig. 3. The code was lost as we moved past using the LED in our circuit.
