Once the Arduino was set up with the lab PC, the first step was to create the capacitance sensor circuit in Fig. \ref{739549}, as well as write the code to drive the sensor. The first draft of the Arduino code can be found in section \ref{153766} and is derived from the code found in the documentation for the capacitance sensor library we used. \cite{capacitivesensor} The starting circuit utilized a 1MΩ R1 and a 100nF CGND. In an adjustment from the proposed circuit, we made CGDN  go into the discharge pin, rather than to ground. When the capacitor went to ground, the circuit was not properly sensing the capacitance and often overloaded. With the circuit built, we needed to create an open capacitor plate to properly test the capacitance sensing capabilities. We decided, given the resources present in the first lab period, to construct a capacitor plate from a single penny and short wire. Once soldered together, we placed our plate into the circuit and loaded the Arduino with the code. Once in, we saw a reading of >100 units on each microsecond on the serial monitor. To properly test if the circuit could see a change in capacitance, Tristan lowered his hand closer and closer to the penny, creating a capacitance between the penny and his hand. As he did, we saw no noticeable change in the capacitance, until he got with ~5 mm of the sensor, at which point we saw the numbers increase to ~2000, with the sensor reading as high as 3500 when fully touched. During one of the tests, we collected 500 ms resolution data, shown in Fig. \ref{918932} and Table \ref{609497}
