Very nicely done Markus... just starting to play with both LEDs and Arduinos. Your breakdown was clear and concise.

Amazing tutorial Mark! I just ordered my led strips and arduino thanks to you!

Now we are onto the ws2813B - 5050 chips, dual data lines for failsafes in an array and way quicker update speed.

Well there's always the argument that: if you do something yourself, despite the fact that others already have done it for you, you can learn a lot and get a deep understanding of the subject at hand ;)

So great to see a new Markus video!

i prefer using fastled. also prewritten code may not work as you want and it can take a lot of time to modify it so i found writing my own code better, and you can be more pround of it :)

In your code, if you assign values to PIN and lightCount as you have done at the top, then you can use those variables in the "strip" definition

at <a href="#" class="seekto" data-time="290">4:50</a>, the purpose of lines 3 and 4 is to have a generic line 13 as: Adafruit_NeoPizel strip = Adafruit_NeoPixel(lightCount, PIN, NEO_RGB + NEO_KHZ800); so you need to change only those 2 initial lines if you change pin or strip lenght...

One question mate: What if I connect to this arduino mega a 12v led strip with 12v power supply, not 5v because my led strip is for 12v only. Waiting for answer, thanks..

Thanks for the interesting video, Markus. I have just received a 30 led strip yesterday and got it working with some code from Nils, Hamburgtech, I think, and it looked quite impressive.Kevin Darrah also has a video on WS2812B strips. I have ordered a 300 led strip so that should be interesting. I like your presentations and esp your own music which is tastefully mixed unlike most on YT. I'm into guitar and electronic music.

Thanks for sharing this with us. That LED strip would be awesome if used at the bottom end of long translucent plastic curtains, hung from a black ceiling to simulate the aurora. Just add a light breeze from a small fan on them. Maybe?

Crystal clear explanations. Many thanks Mark. Very, very, very well done.

Your calc giving 5V at 2A is a bit off... 144 LEDs at 60mA/LED (20mA each for RGB) comes to 8.64A at full brightness white (43.2W) - you need a 10A supply if you're going to drive a 1m strip flat out. Also , you shouldn't have the 470R in the ground lead.. this may cause a voltage difference between the strip and the Arduino that may make data transfer unreliable. It may be necessary in the data line from pin 6 but you should connect the ground directly, without the 470R.

Each led at full power is 60mA, by 144 leds is 8.64A, so 2A is far from enough. An ATX power supply is a juicy and cheap/free candidate.

What is the actual sketch name you are using from the Adafruit Neopixel library as there a few to pick from. Thanks

where did he connect the capacitor?

Nice to see you've caught the Arduino bug....👍 I've got it so bad I build my own now.😕 BTW I was shouted at for saying I was 'linking 'X' to the negative..' Apparently I should have described it as 'common'.

I've got some videos on my account for using these individually, creating an 8x8 matrix (1 meter square). Lots of soldering (basically, 6 points per, times 64). They are a lot of fun to work with, especially with a ESP8266 wifi chip to remotely push or pull data to them.

If you want to extend this idea you could go for a spectrum analyzer with e.g. 10 leds per tone. There is very useful microchip out there called MSGEQ7 (cheap and relatively easy to use). It is a seven-band spectrum analyzer and is very commonly seen in led-music kind of projects.

How to change mic to audio jack input ?

VU's usually go from green to red through amber (as you no so adjust software ?) and you don't need the 470 ohm on the ground line but a 100 mike Elec cap across VCC and GND will stop any supply voltage spikes. Your diagram is a bit misleading as it shows the "strip" as a 2 wire device, it should show VCC,GND and DATA..... you have a powered breadboard so point the cap out or include on diagram Pls (just thinking of your less experienced viewers) ........Love your style keep it up!

This seems easy for a beginner like me :) I have the components so here we go..... actually I have 2 strings of 144 lights but lets just start with one LOL Thank you Markus!!! You have a new Subscriber :) OHHHHH one question actually.... Do you have a link to the sketch you used for this? Many Thanks!

Dear Markus, nice work! Coud you please provide me the Music at the end <a href="#" class="seekto" data-time="872">14:32</a> Thanks.

would you be willing to sell a fully setup arduino without the led strip lights ? electronics is not my thing. if so let me know

thanks man I'm always looking forward to your new videos

Sorry to bother but, How did you get it to center in the middle of your string and expand outwards? Is there specific coding that you added or is it default in the Neopixel library?

It's been a while! Great video, as always, and I'd no idea that one could fit a micro controller onto the same LED it was controlling.

Can the dynamic range be adjusted? It looks like it doesn't start from LED1 going towards the end of the strip. It looks like it only lights up a few LEDs over. As you change the pontentiometer it starts several LEDs further up and again it only goes a few more LEDs down the strip. In other words, can you adjust it to where the lowest dB will light up LED 1, and max dB go all the way to the end of the strip?

Can you use a no powered microphone instead of a powerd because i only have a 2 pin one availible and if it goes how do you connect it

Hi Mark, 👍 another great enjoyable video. Just thinking the led strips would look good stitched down "you know who's " trouser leg when he's playing the pedals!😂 Cheers Nigel

Great video! I just had two questions: How did you hook up the capacitor? Also, at ~<a href="#" class="seekto" data-time="50">0:50</a> seconds you show a room with LEDs around the top. Ive been wanting to do that as well, but haven't figured out a way to power a strip long enough. I currently have 13 meters of WS2812B, but how would you recommend going powering them in-line? Thanks again for the great video!

Great video is there a way I can connect more strip lights . Thanks

gr8 video, good explanations that surely help a beginner. thumbs up.

do u think it would be possible to replace the mic, like just the mic with an auxilary port and input music from a pc or phone directly? thx mate

How can you power 15metres of these? Same way?

Hi. Thanks for share, I am going to build one for me. Let me ask. What is for the 470ohm resistor in ground led strip?

Good video, the first I have watched from your channel. One thing if you not already done is to mono your audio. It flicks around from left to right .

well done as usual, and your music composition was nice too

Markus but the programming code did not put it in the link to download it.

Nice to hear some of your music too.

Is there any way i can listen to the music you've made? Always wondered because I hear that music alot in your videos and I like it.

I will try that resistor config. I have just been using a single 1 to 10K resistor for noise and other interference but its not good enough. I have nearly 1500 of these in the lounge room and interference can be a major issue. For example 1 string can wirelessly send very accurate interference to another string not connected except power. Also some DMX devices can be very noisy(cheap shitty switch mode power supply's).

تو خیلی فوق العاده ای\ so good.very excellent

I'm just getting back into electronics after a 20+year absence ............................I am SO, SO BEHIND THE TOMES..... :)))

Thanks Mark. Please make another tutorial with EQ7 IC. A very interesting controller from Vivi you should look at.

so pertaining to the voltage of the capacitor isnt it best to closely match the power out put to the leds please correct me if im wrong but couldnt a 16v cap possibly charge up to that 16 volts even if only 5v is being supplied and possibly send a power surge to the leds?

Vu meter connected on the pc in the windows sound at maximum does not blink, only when the volume below it blinks. How to leave the sound at maximum and the vu meter blink? Stereo Vu meter arduino nano. Thank you very much.

would the same resistor be used if i had a bigger strip say 5 meter with 300 led sorry i am a nob in this hence asking

Nice video Markus and awesome music :D

Hello! I just stumbled onto your channel and really enjoyed this project... thanks for sharing. I also like the composition at the end of the video -- is it available to buy anywhere? Or if it's free I'd still like to kick a couple of bucks your way. Cheers!

do you have a band camp? where do I get your music. it was quite nice

I need help with the 12V 2815 and how to wire an Arduino Mega

Is there a noticable difference in the brightness between the 60 LEDs/m and the 144 LEDs/m strips at a big distance?

Do you have the chase sketch? I can not find one I like, can you link it.

can you put the links of every part i need to buy?

New to arduinos, does it matter what board you use? There seem to be quite a few Arduino mega boards out there.

very good video

How would you wire this up if you had multiple strings of the WS2812's and they aren't daisy chained?

Hey I'm interested in getting into the Arduino stuff. Is the're a kit that you could recommend for me? Thanks

Is the Rubik's cube at <a href="#" class="seekto" data-time="483">8:03</a> fully solved?

Very nice vid thanks

Wow. That's a lot of current.

i like your work shop.like to see more of it-for inspiration.DON

You need variable dynamics to oomph up your leds. Try grunge...Lithium should do it...Nirvana.

Help!!! I have tried to upload the code for this and I get an error all the time, any help please

Hi mark thanks good demo, i have one project to set up LED for exterior --> need ur support... let me know how to contact you... thanks

So at 5V and full brightness it only uses 2A. Ive heard on bangood that these can use up to 42W.

Hello Markus, is there any change that you could share the code you used for this?

i wouldent mind listning to more of your music i like it

Is it possible to have 15 meter of these 144 LED/m strip? and still control each leds?

for stereo?

i have ws2812b 300leds in 5 meter ...i have 5v 8A power adaptor and sp103e controller and still not working.... for the first time i made a mistake...i plug in the controller into 12v adaptor...waw very hot temp... did it was broke? know what should i do?

Very good.....

Found the code: forum.arduino.cc/index.php?topic=284371.0

Can it be done without the capacitor... cuz i don't have one.

The 470ohm inline resistors are not really needed, especially on the ground...

Спасибо!

Where i can find the code man

AMIGO ONDE BAIXO O CÓDIGO DESSE PROJETO ? A UM BOM TEMPO QUE PROCURO UM PROJETO COMO ESSE.

Where is the arduino code.

Dear Markus I discover one tecnic device in not at all on the market and only sony make it at great price as sony usual do . I'm talking about to make a 2.5 ghz remote for every portable audio recorder I 'm not talking about video recorde but a remote to insert in every audio recorder lik for instance H1 zoom mic , I hope you know it - well with all your "Know how" I'm sure you will get to creat it . somenting to insert in the h1 zoom device and to control it from distance with gh2.4 remote and not at all bluthooth remote - I give you this idea to work on it and if you get to realize it you will become rich and famouse .All the music comunity and actors comunity can need it for outside use in the real world with the sky over your head not in studio I mean .Forgive my English it is not my language but I hope you have understtod what I mean . Thanks by Tony from Rome Italy .

Every tried Glediator ? amazing little java app to control strips / arrays.

vas it a yamaha montage you had there in the start before 1 mins when you show around the room :D

It is posible to multiplex the leds to save current?

i just bought 5m 30led payed 16.06 cd at aliexpress they are always cheaper then banggood

where is the code?

Want this Steinberg tee

Your microphone is not providing enough signal to use the full range of the VU meter you should install an op-amp or a Darlington pair to boost the signal.

how is it addressed?

Play Dark Side of The Moon, "MONEY" You young fellows have no idea what REAL music even is any longer.

Lol you sound like a big youtuber i just dont know like who at the moment

Any 2 legs mic please send me

could you send me a link to the code please

Steinberg T-shirt.

hi can i get the code u use for this project please

I want to buy.

MIC drawer - funny. :o)

Get them directly from China, they are like 1-2£ per meter ;)

Microphone, variable resistor.... it's all the same, innit. ;)
