Description
Shield for Arduino is equipped with a filter for the graphical display of the audio signal amplitude. It allows you to split the sound from both stereo channels on 7 bands, and read the amplitude of each of them with the built-in Arduino converter A/C.
The module has two connectors stereo Jack (input and output) for headphones and speakers. One of them is the standard audio input is stereo, the second output to connect speakers or headphones to the signal from the input line.
Shield can be used to visualize the frequency of the sound (equalizer) to detect patterns in music or to activate a function based on the detected sound.
