During Fall term 2023, Marc and Jacob have noticed possible issues with the flow meter. It seems that noise on the 3.3V lines can cause voltage drops and spikes that cause the Feather to count additional flow ticks that will result in inaccurate flow readings.

We don't have time right now to diagnose and troubleshoot these issues, but in the future some noise-reduction should be employed to reduce issues with the analog sensors.
