• Description
• The SparkFun Sound Detector is a small and very easy-to-*** audio sensing board with three different outputs. The Sound Detector not only provides an audio output, but also a binary indication of the presence of sound and an analog representation of its amplitude. The three outputs are simultaneous and indep***ent, so you can *** as many or as few as you want at once.
• The envelope output allows you to easily read amplitude of sound by simply measuring the analog voltage. Gain can be adjusted with a through-hole resistor to change the threshold of the binary(gate)output pin as well. Check the hookup guide below for more information about setting gain.
• Each of the three output signals is present on the pre-soldered 0.1" header at the edge of the board. They are active simultaneously. If you aren't using one in your particular application, simply leave that pin disconnected.
