wow

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.

Thank you for the clearest explanaton I've seen!

Such a clear explanation.God bless you, sir !

every body know multimeter brand and model?

Sehr gut

This video is so much better than all the videos I saw on you tube until this time 🙏thank you sir

How is this applied, and to what? Can it be applied to sound, and how? Thanks for taking an extra step to explain!.

Nice video, thank you. I just purchased this generator this video is very helpful.

This is awesome

Excellent!

9 years later and it is still helpfull thx doc :)

Is it just me or none of these videos have audio? 🔉

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

My GW multimeter gdm 393 not working scrin fuge open after scrin work

hello sir, is it possible for me to reach out to you for help with a circuit? i have a very complex circuit on paper but i just cannot make an actual circuit out of it

Great explanation. Thanks for posting!

Worked for me, thx 😎

What was the version of the arduinoFFT library you added when you made this video, the latest version seems that it is not working

My old Motor Chief Warrant Officer used the KISS moniker as well. Lol.

Thank you for doing a great video!

This video really helped me out, thank you for the step by step breakdown

how can I get the instantaneous output received from a Arduino mic, as I do not wanna use SD, pre-loaded MP3, WAV or any other stored data. I need live IP to OP.

This literally saved me my god you made it so easy to understand

Your work is not clear.

Have a question? What is the purpose of removing the other end of the resistor to a different hole when checking current?

Thanks sir

stupid man , i want know multimeter brand and model😡

Very nice

Thank you for the informative video, If the equipment errors is larger than the standard deviation? how do we write the uncertainty value for the final results?

6 grade school talk

Want the hand brake light switch not foot brake

Is there a difference between standard uncertainty and uncertainty or are they the same thing

Awesome work man.

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.

Thankyou.It was helpful

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.

THIS IS INSANE CLYDE LETTSOME!!!!!!!! LOVE FROM NORWAY

Why are you doing this

Scopes are really tricky bits of kit. Especially at first. We just started using them in lab a week or so ago and the instructor was just kind of like “figure it out”

Very helpful and easy to understand for beginner's like me. Many thanks.

Why is the music SO LOUD?

Thank u.

Very vague diode testing,should show a bad diode too

Hi Sr. Its all the cards that we need study for eta certificate?
