I bought the sound sensor (YwRobot 537473). I've found many examples that detect volume using the sensor, but nothing that detects tone or pitch. For grins I'd like to see if I can make a simple guitar tuner. Is it possible with this device?

Well a link to the sensor would help google turns up nothing.

However if it is used to measure the volume of a sound then it is likely that it is a peak detector followed by a filter. In that case it will not let the full audio waveform into the arduino in order for you to make these measurements.

Yes just like I said, you can't get sound signals from that board only envelope information.

Do you have any suggestions (link) as to what I should get if I want to make a device that can determine the frequency of a sound?
