Use the ADC in continuous sampling mode at a fixed frequency > 2x as fast as the fastest frequency I'd like to detect, per the Nyquist Frequency Theorem. We want continuous samples with zero missed ...
For the competition RoboSub, an Arduino-Due needs to be able to sample and compute a Fast Fourier transform on an incoming ping. Since there are mutiple pingers in the pool, the submersible needs to ...
