My Weekend Project: Audio Frequency Detector Using An Arduino
This Arduino project displays the approximate frequency of the loudest sound detected by a sound detection module. For this project, the analog output from the sound module detector sends the analog audio signal detected to A0 of the Arduino Uno. The analog signal is sampled and quantized (digitized). A Fast Fourier Transform (FFT) is then ...
