DIY LED Music Visualizer | Real-Time Animations (Arduino)

[@DevonCrawford]

Based on the amount of requests I have decided that over the next few months I will be working on perfecting the LED Music Visualizer and adding a ton of features to make it a "real thing". I need to know how many of you actually want one. Fill out this form if you would actually buy one for roughly $50-$100 (16ft LED strip + controller): goo.gl/forms/LG7264d0h5dTnG5w2

[@patrickwilson9111]

Devon Crawford i would definitely cop, I just had one suggestion that I think would make it insanely cool.. if you could hook up multiple led strips with the same output it would be fantastic

[@capricorn3d828]

does it ship to europe?

[@DevonCrawford]

Patrick Wilson for sure will implement this 👍

[@DevonCrawford]

Capricorn3D we are trying to ship worldwide. Once we get there we will see if we have any issues

[@christiannunez1438]

Devon Crawford curious bro. Just wondering. How is this LED strip different from the "dancing line" lights feature sold on amazon? I was looking at that a while ago, but I didn't order it because it didn't work with other sound outputs, like if you wanted to listen to your music discretely using ear buds but still wanting to see the light display. Also, if you do end up shipping these, can you make an app for Android that can remotely control the LED strip like turning it off and on and customizing the lights?

So, you actually inspired me to make this project for myself for fun, but while i was working on the Hz to V converter, a class mate asked me about what I was doing and after I explained it, we decided to add it to the project list for my schools robotics club, and we've been having a TON of fun building it so far. Thanks for the idea!!

[@CAPTINBARNEY]

This is so cool, I have an idea, have 3 strips and have the bottom strip only respond to bassy low frequencies, the middle strip can be the mids and the top strip the treble, I think that'd look sick

No.

they will look all different then... visually if you can think ... need to sync the rhythm...but that's your idea and I will look forward if you do some good with it.

[@catto5600]

A simpler approach to this is using a Bluetooth shield to get real-time pitch data and update the LED's based on that. Nice video, and it's nice to see you take the complicated route!

[@F1mus]

This is really cool... I think the formula you were looking for is Hue, Saturation, Value. Hue is the color, saturation is how gray it is, and value is the brightness. Hue is measured in degrees from 0 to 360 (0 is red, then 360 is red again after going through all of the colors of the rainbow). You can map whatever you were doing with your if statements to a hue, and then convert the HSV values to RGB to set the color of the light.

[@mikeverschuur2713]

Well, that is just amazing.... Do you have a list of all the components you used to make it? And is there any tutorial how to put it together? :D

I'm trying to recreate this, I'm wondering how the arduino is worked into the circuit. Is there a picture I can use for reference?

[@RobertBarton86]

I'm totally late to this party, but you could use gradient palettes in FastLED to map the values to RGB. You setup colors at several values between 0 and 255, and anything in between those colors will blend. I use these with my 600 LED setup to get cool effects like flame animations using rainbow colors. Anyway, awesome video! I may be attempting to duplicate this on my setup soon.

[@Mar_INT]

what if, crazy idea though, you had the pitch control the animation and the volumen the brightness of the LEDs... just my random thought dumped in your comment section though.

Couldn’t you just map the frequency range (~200hz-16khz since the rest is mostly inaudible) across the color range (#000000-FFFFFF) instead of using that series of if statements?

[@AndreasInGreer]

Not with this setup. This is based on total volume. There is no analysis of the frequency band, however, THAT would indeed be awesome to map the frequency to groups of LEDs and then change their brightness based on the amplitude of the frequency sections.

[@PaulFerzoco]

Nice design. Has a lot of potential. I built one of those back in the 80's using some 74xxx IC's that fed into some MOSFET circuits to provide the needed amplification. Worked great, I think it was 16-channel (I could be wrong - I'm gettin old). Anyways, in those days we did everything more simply. No computers. Wish I had the circuit diagrams - I'd send them to you. The channel outputs were programmed with just resister/capacitor combinations. I used to sit in my basement building shit just like you do on the same breadboards. Good luck!

[@dannyvanderheide6098]

probably because a microphone has a tiny voltage and then it would react on any sound that happens, imagine watching a movie and those lights constantly go bazark

[@arunavdey]

@@dannyvanderheide6098 You could change the sensitivity of the input using a potentiometer though, it's a cool idea.

[@MegaMino31]

Great work and great effort keep the good work going. I actually figured out why the Frequency to voltage converter chip was not working. If you directly supplying the signal from phone your phone to the frequency to voltage converter circuit, this is probably why it was not functioning as it should be. This chip even the second circuit you ended up going with expects a frequency modulated signal, look up FM modulation if you are not familiar with the term. Basically, you need to supply any freq to volt converter with an FM modulated signal (Fixed amplitude and varying frequency). If you want to improve the current design I suggest adding an extra stage before the FtoV converter which handles the FM modulation. this should allow you to scale 20 to 20khz (human hearable frequency) to any voltage range you want 0 to 3.3 or 0 to 5 depended on the MCU you are using.
