| - | * Modified the algorithm and successfully implemented wave-counting using hardware interrupts and voltage thresholding, for one microphone only. The experiment involved playing a sound wave with a known frequency and then having the Teensy measure how long it takes to "see" 1000 periods of that wave. From that measurement and the number of periods, we can derive the frequency and compare it to the frequency of our emitted wave. The experiment was successful as we were able to derive the emitted frequencies. | + | |
