Hi, I have just tried this and several other projects that use FFTand always get this error, I am using the latest "arduinoFFT" library 2.0.2 by Enrique Condes : error: Compilation error: 'arduinoFFT' does not name a type; did you mean 'ArduinoFFT'?

@CALettsomePhDPE - is there any way to extend this for analyzing and detecting a specific sound in the array of sounds? and what needs to be done to make it 360-degree capable? add 2 more mics and place them in a circle for every 90 degrees? am I thinking correctly? Awesome video

Re-establishing fundamentals for the Power PE after a few years of industry work and I found a video uploaded by an alumnus of Georgia Tech with a mind-blowing background. I am so glad that I found your ece videos because your videos truly shine in a sea of low-quality and/or unreliable educational materials.

Is it just me or none of these videos have audio? 🔉
@ChronoGXay3 ай бұрын
My OFFSETSAMPLES are all always zero (I'm really not sure why- maybe this is why my frequency results seem almost random). I'm using the same analog audio module, I've calibrated the potentiometer very well to where the sensor LED only comes on at all with so little as a finger tapping on the table, I have double-checked that my wiring is the same as in the video, and have copy-pasted the program from the website. Do I need to use an external pulldown resistor since this is an analog input? If so, what value approximately?

can you demonstrate this via a spectrum analyzer? I was hoping to see all the frequency components of a given signal

Thank you for a very informative video. I especially liked that you showed that some of the insulation was also wrapped around the bottom of the pin as this adds strength to the wire so it has less of a chance to break due to vibration or other movement.

If both separate channels are connected in series, won't the zero center be drawn to the terminals CH1+ and CH2-? The connection will certainly occur, but it may not be output to the output terminals and this will only double the voltage of the sum of both channels. But if the center of the connection of both channels is brought out to the output terminal (mostly channel CH1-), it is much easier and no jumpers are needed.

In order to make the program display how close the played note was to the closest match in the storedNoteFreq array, I added the following in the section you titled "Find the closest note": noteLocation = i; cents = 1200 * log(storedNoteFreq[i]/signalFrequencyGuess)/log(2); if (cents < 0) { flatSharp = "flat"; cents = -cents; } else if (cents > 0) { flatSharp = "sharp"; } else if (cents = 0) { flatSharp = ""; } I then had this display in the printed output as... Serial.println(octaveRange); if (cents == 0) { Serial.println("You nailed it!") } else if (cents <> 0) { Serial.print("You were "); Serial.print(cents); Serial.print(" cents "); Serial.print(flatSharp); Serial.println("."); } What do you think? (NOTE: Don't forget to add "int cents = 0;" and String flatSharp = "";" to the variables at the very beginning.)

I think it would be very helpful to make the program take a sound sample during the countdown to determine the ambient noise level, set a volume threshold based on this, and then when cued have it iterate repeatedly through the available sampling memory for even half of a second, sensing for when a sample’s amplitude exceeds the threshold.
