I have seen many videos on RU-vid of people showing off their arduino music visualizers, but no one seems to want to tell you exactly how to do it. This video will show you how to make the visualizer from scratch.
The sparkfun spectrum shield is the key to this project. It allows you to take an audio input, split it into seven bands, and analyze each band separately.
The strip of individually addressable LEDs allow you to control each LED separately from one another rather than being limited to controlling all at the same time.
The pattern I have chosen for the visual effects is a rainbow wave which expands out from the center.

@EnderGeneral149 3 года назад

@@JustCallMeKoko Funny story, I had just put it up when I noticed an issue and I was hoping you could offer some insight or advice on how I could fix it in an efficient manner. I noticed that when using an even number of LEDs, the first LED doesn't get lit in the double rainbow mode. My setup was using 92 LEDs, so the midway value would evaluate to be 46 and if the lighting is always symmetrical then of course that would mean the rightmost LED would never light. I tried to find a solution myself that without just cutting off an LED, but I would be stuck here for who knows how long, so do you think some insight could be given? I am sure you are busy, so sorry ahead of time if this is a silly request (or if it turns out being a stupid easy solution)

Good work buddy ! I had some issues regarding making taking the audio input from my laptop or phone to the breadboard. I mean, can this be done without using the spectrum board ? Also how do you connect the 3.5 mm headphone jack to the breadboard (silly question, I know !) ?

@JustCallMeKoko 5 лет назад

If you are actually using a spectrum board, then yes the audio would plug directly into it. If you are just using an arduino with no spectrum board, you would need to find a way to connect the 3.5mm jack to the analog input on the arduino. In that case, I would use a 3.5mm audio breakout board.

@DJDevon3 5 лет назад

You increase sensitivity by multiplying the input or output. You could do it when the audio value is ready for output. Something like audio1 = audio1 *2; directly before the analogRead(audio1) line. Keep in mind if you have a weak audio signal there's likely going to be a lot of noise in the signal which will get multiplied as well. Getting rid of static and hum prior to the signal hitting the spectrum shield would be something to look into cleaning up. You can find line conditioners for it.

@robertsyrnicki5638 4 года назад

Cool video. Does anybody know how to connect an Arduino instead of a speaker driver, so it is possible to read the frequency without outputting any sound?

@tattoomafew2316 2 года назад

He is using an Arduino. If you don't want to use the SparkFun Spectrum Shield, you'll need a sound sensor module. You just connect that to A-0 instead of the Spectrum Shield. Any noise the microphone picks up on the sound sensor will return a value to the "audio_input" variable like the Spectrum Shield would, but you might get interference with background noise depending how sensitive the sound sensor module is set.

@ruikka9748 5 лет назад

Hello and thanks - really a great project! I've added "audio1 = audio1 * 2" (where you said to) to increase the reaction to sound (using my phone's output on highest volume, only half of the LEDs are lighting) and this had no effect. "* 4" and "*6" also had no effect. Any ideas? Would really appreciate the help. Cheers! Anton

@ekremruzgar9521 5 лет назад

Because you give so low ampere to ws2812b (Arduino's 5V output give 40 mA). You should use a 5V DC power supply. And you must multiply your leds quantity with 60 mA (Because every led needs to 60 mA). For example I have 120 led. This meaning I need to 7.2 Ampere (120 x 60 = 7200 mA = 7.2 A) So I can buy a 10 A power supply. Your power supply's ampere value can be more than the ampere you need. Then you should make a circuit like this ↓↓ cdn-learn.adafruit.com/assets/assets/000/030/892/original/leds_Wiring-Diagram.png

Is there a maximum amount of LED´s that you can use? I have 300 planned

@JustCallMeKoko 5 лет назад

As long as you have a good power supply, there is no limit other than array size. The arduino UNO does not have a massive amount of memory, but 300 should be fine

@DJDevon3 5 лет назад

@@JustCallMeKoko Yup with an external power supply and an Uno you could realistically do close to 600-1000 depending on your code before you hit the Arduino's memory limit. That's just a guess. At that point you would be ripping out every byte you could and trying to make smaller and faster code to save space for faster cycles. Otherwise the animations would slow down so much it wouldn't be much of an animation at all. At the upper limit you'll likely notice the animations going slower and slower the more LED's you add to the array. I'm sure someone out there has figured it out for the Uno. I tried looking it up and couldn't find a specific clear answer. I am controlling 300 WS2812B LED's from an Uno and Nano. 600 total on 2 devices. I haven't tried more than 300 on one so that's all I can confirm. I'd like to know. Your spectrum sketch is awesome on 300 LED's. :) I think the people doing bigger displays are doing matrix's. A 17X17 matrix is almost 300 LED's. So look for arduino projects that have bigger matrix's than that.
