SparkFun Spectrum Shield Brand_FlightAware and other structuresThe SparkFun Spectrum Shield enables Arduino projects to react to sound by splitting stereo audio into seven frequency bands per channel, making it ideal for audio visualisers, interactive lighting, and sound reactive projects. The SparkFun Spectrum Shield equips your Arduino device to split a stereo audio input into seven distinct frequency bands per channel. By reading the amplitude of each channel using your Arduino's analogue to digital converter
