|Arduino Uno Compatible Dual Channel MSGEQ7 Spectrum Analyzer Shield Board
Boards - Electronics
The Arduino Uno Compatible Dual Channel MSGEQ7 Spectrum Analyzer Shield divides the audio spectrum into seven bands, 63Hz, 160Hz, 400Hz, 1kHz, 2.5kHz, 6.25kHz, and 16kHz. Seven frequencies per channel are peak detected and multiplexed to two 0 to 5vdc outputs that provide analog signals of the amplitude of each band. Its form allows for stacking as a shield on the Arduino Uno microprocessor. The board is supplied with regulated DC (5.5VDC). The multiplexor is controlled by a reset and a strobe, permitting multiplexor readout with only two pins.
