Making a 144 LED VU meter from arduino and ws2812 addressable leds
HTML-код
- Опубликовано: 17 авг 2016
- this is all new to me but its time I started to learn about the arduino and programmable leds.
the leds came from banggood.com for me to make this video.product link bit.ly/2bhKQo6
Music available for free to use download at / markusfuller
I'm a complete newbie with arduino but I hope this will be the start of some interesting future videos as I have a few more items coming from banggood to try out in the near future.
all music used in this video was created by markus fuller 2016

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!
hello,if you need ws2812b led strip light,please contact to me.

Crystal clear explanations. Many thanks Mark. Very, very, very well done.
So great to see a new Markus video!
Thanks Michael. sorry its been a while. been working.
Anything but that!! ;)
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.
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
thanks man I'm always looking forward to your new videos
sorry i have been away for a while (work work work)
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?
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?
well done as usual, and your music composition was nice too
Thanks Vince. much appreciated
How to change mic to audio jack input ?
gr8 video, good explanations that surely help a beginner. thumbs up.
Do you have the chase sketch? I can not find one I like, can you link it.
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
Help!!! I have tried to upload the code for this and I get an error all the time, any help please
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.
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 :)
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?
What is the actual sketch name you are using from the Adafruit Neopixel library as there a few to pick from. Thanks
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.
Hi Michael, sorry I have been away for a while (work work work) but im back now with a head full of ideas.
markusfuller Looking forward to it!
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..
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
Im still banging my head with arduino code. Im a little bit behind but running as fast as i can.
Hi Mark, your video was very informative. But I was wondering if you still have that red green blue chase code?
Nice video Markus and awesome music :D
Thanks DrummingEvil. i'm looking forward to trying out new things with the arduino.
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'.
Yes I really need to get into this arduino stuff Im amazed at what you can do with it. Oh common - negative - ground its all the same at the end of the day.
markusfuller Like you I've found adjusting other people's code is the best way forward. I have written my own for a recent project, but on seeing it a programmer friend of mine exclaimed 'my eyes, my eyes!!' 😳
look into ColorChord by CNLohr
Thanks funnybastard I just went and watched that video and realised just how far behind I am. it looked really good. many thanks
Markus but the programming code did not put it in the link to download it.
can you put the links of every part i need to buy?
Dear Markus,
nice work! Coud you please provide me the Music at the end 14:32
Thanks.
تو خیلی فوق العاده ای\
so good.very excellent
at 4:50, 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...
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.
Hello Teemu. I only really make music for simple pleasure and most of the music in my videos are just snippets of pieces I put together during the week and most are never a complete piece so there are no full length pieces of music that I can share that would be any good. theres a couple of pieces I placed on soundcloud soundcloud.com/markusfuller . I will try to add something in the future if I make something a full length piece. Many thanks from Markus
where did he connect the capacitor?
Very nice vid thanks
I need help with the 12V 2815 and how to wire an Arduino Mega
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
That would be a great idea but I would have to plug him into the mains somewhere ? LOL
+markusfuller worth considering!
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 .
Hi Yes I kind of did a bit of a rush job on this video and experimented further afterwards.
very good video
Is it possible to have 15 meter of these 144 LED/m strip? and still control each leds?
theoretically YES.... but do ya Power math!
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?
zack lariviere Hi a 16v capacitor is just the safe limit it should operate at. if you have 5 volts going into it then it will stay at 5 volts. think of it as an egg box, it can hold sixteen eggs but you only have 5 in there but it can safely hold 16 if you placed 16 in there. hope that helps, best wishes from markus.
Thanks for responding
Very good.....
Is there a noticable difference in the brightness between the 60 LEDs/m and the 144 LEDs/m strips at a big distance?
StarTrek123456 Hi I only used them on the desk but I guess at a distance the 144 led version will be brighter.
Nice to hear some of your music too.
Thanks it was just a quick 3 chord trick to get something recorded for the video.
No need to knock the three chord trick... Being a "one finger player" I tend to go for the three note trick ;)
LOL been there myself many times
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?
actually that sounds a very good idea Thomas.

How would you wire this up if you had multiple strings of the WS2812's and they aren't daisy chained?
Hi I think you can run several hundreds of these in one row especially if you use something like the teensy 3.2 . but I think you can also use several outputs from an arduino running into each length of ws2812s but your coding would have to take this into account. say row A on pin 6 row B on pin 7 etc etc until you run out of outputs. but the arduino will run large amounts of these ws2812s.
Now we are onto the ws2813B - 5050 chips, dual data lines for failsafes in an array and way quicker update speed.
i like your work shop.like to see more of it-for inspiration.DON
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.
Hi Greg Im truly a newbie in the arduino/raspberry way of making things. I will certainly go and check your videos out as I want to learn more and more and more. many thanks.
No problem. Drop me a note if you have questions you think I might be able to answer.
Thanks Greg thats very much appreciated.
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
Hello Yes you can connect directly with a phone or mp3 player etc. you would just need to trim the potentiometer. I tried it after making the video.
damn, thx budd, cant wait for my leds to come, thx dude
How can you power 15metres of these? Same way?
Спасибо!
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 ;)
True and I did learn a lot looking through the programming and changing a few things along the way so see what happens.
Can't wait to see your next project ;)
Speaking of which: there's some great projects and libraries for DSP on the Arduino, you should totally check them out!
I like the music - but it does sound somewhat digital in a dx7 style - what synths are you using? - because it would be interesting to hear a more anolgue-y (is that a word ?) version with some squelchy filters etc.
p.s. love the video - and thanks for doing this.
Thank you very much. hopefully as i learn more about these arduinos i will try and make something interesting.
Great video is there a way I can connect more strip lights . Thanks
Yes, you can just add more to the end of the existing strip, and change the number of LED's in the code. Be mindful of the power requirements though. A 144 LED strip at full brightness White can use up to 8.7 Amps (20mA per RGB *144 LEDS). Using the FastLED library for Arduino you can limit the power usage with a line of code. For example :-
FastLED.setMaxPowerInVoltsAndMilliamps(5, 2000); will limit the led strip to approximately 2 Amps at the cost of running the LED strip at a lower brightness.
for stereo?
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.
it is even possible to jimmy more than one together for a 14 band spectrum analyzer and so on
I have so many ideas but lack the knowledge of arduino. those MSGEQ7 chips sound interesting . many thanks
Great video! I just had two questions: How did you hook up the capacitor? Also, at ~0:50 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!

Hello Markus, is there any change that you could share the code you used for this?
Hello the code came off the adafruit website. I just searched for ws2812 vu meter code.
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).
Use capacitors in parallel to power and ground. Always use the resistor on the data wire, but not on ground. Grounds should be all connected together and with solid wire connections. Only one resistor is required, coming straight off the Arduino's pin. The rest of the strips can be just chained together.
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?
tuah cool Hello. you may have overloaded the controller and it could be damaged. if it is an arduino there is a small green flat component on the board which may have an "f" printed on it and that is a fuse . maybe you could check it with a multimeter and if you are lucky that may have blown before any real damage was done to the chip.
oh men... i not using adruino
i am using a simple controller SP103e
and if in the future i buy adruino? what V is it? 5v?
Hey I'm interested in getting into the Arduino stuff. Is the're a kit that you could recommend for me? Thanks
Get an Arduino starter kit with Arduino Uno. When you're a bit more familiar with the Arduino, you can try the smaller boards, or even an ATtiny85. You need a shield, a dedicated Arduino board and the ISP programmer scetch to program the ATtiny though. This information will all be available online, just ask google.
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.
Hi Steve, your calculations are correct but I was only going by what my PSU was displaying.
Because you'll mix colors, you'll never gonna use 60mA. More in the range of 20mA
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.
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
do you have a band camp? where do I get your music. it was quite nice
Hi I only have a few pieces of music that I have put out and they are on soundcloud under the name markusfuller and Its free to use if you want any of it to use for your videos. I will try and put more audio in the soundcloud as I go along. best wishes from Markus.
New to arduinos, does it matter what board you use? There seem to be quite a few Arduino mega boards out there.
Jessica Haskins Hi Jessica. I cannot keep up with the amount of types of arduino you can buy, I just bought the mega for the extra pinouts and larger memory but I have never used those extras and could have done everything on a smaller cheaper one.
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!
Thanks Mark. Please make another tutorial with EQ7 IC. A very interesting controller from Vivi you should look at.
Hi Joni, that looks like an interesting chip. I will read up on that thankyou.
Hi Mark. This is a very interesting link to look at www.dfrobot.com/wiki/index.php/Bluetooth_Controlled_RGB_LED_Strip_Kit_SKU:_KIT0069
Thanyou for that link. I will go and have a read up. best wishes from markus.
Is the Rubik's cube at 8:03 fully solved?
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!
Hello Jims408 I have been placing my music on soundcloud soundcloud.com/markusfuller I made them all free to download and use however you wish (just credit markusfuller)
Best wishes from Markus
Thanks!
Can it be done without the capacitor... cuz i don't have one.
Not without the risk of ruining the led strip.
It is posible to multiplex the leds to save current?
I really do not know that to be honest but you can use every odd or even numbered led or every third and switch them quickly.
No. If you try PWM controlling the strips, they will reset and lose their data after power off. They need stable 5V and data. The data signal already does the PWM to mix the colors inside each LED. The only way to multiplex them is through the data pin.
So at 5V and full brightness it only uses 2A. Ive heard on bangood that these can use up to 42W.
Each LED uses about 0.06A according to their specs. So 144 LEDs/m = 144 * 0.06A = 8.64A. Multiply that by 5V and you get 43.2W/m
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
i wouldent mind listning to more of your music i like it
Thanks Dan, I will try and use my music a bit more often in my video's as normally it never gets heard.
cool
sounds great (get it sounds lol)
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!
Hi John. sorry it was a long time ago I cannot remember where I got the sketch but it was probably on the website called github .
@@markusfuller You threw a couple capacitors in there but they don't show up on the wiring diagram... where did you put them ;) Thank you!
@@TheCowboysdude Hi John. the capacitors were placed across the power to help smooth the voltage from my power supply. they are not needed if you have a good smooth power supply.
@@markusfuller Once again Thank you!!!
how is it addressed?

Hello Mark, I started at the adafruit neopixel library and followed links from there. learn.adafruit.com/adafruit-neopixel-uberguide/arduino-library-installation
Where i can find the code man
I no longer have the code for this project as it is quite a few years old now. my apologies.
@@markusfuller help me to get that code
You need variable dynamics to oomph up your leds. Try grunge...Lithium should do it...Nirvana.
vas it a yamaha montage you had there in the start before 1 mins when you show around the room :D
Yes I have a Yamaha Montage,
where is the code?
i just bought 5m 30led payed 16.06 cd at aliexpress they are always cheaper then banggood
The 470ohm inline resistors are not really needed, especially on the ground...
The resistor inline with the data wire is not vital, but is a good practice. It protects the chips. The one inline with ground is not necessary. Common grounds should always be connected together with solid wire connections.
Every tried Glediator ? amazing little java app to control strips / arrays.
I was watching those vids last night. I think i need to buy a lot more ws2812b's
It does allow you to set array size to one so you can use on a string and it has sound / beat detection built in , might still be fun to see how it handles the different effects even on a single string. Also I must do the same been meaning for ages to try them out , how was your experience with getting them of bangood how long was shipping ?
+Darren Woods Hi Darren, they arrived in about 5 days which was pretty quick. I think they must have a warehouse in the uk ?.
they might or they might be up to what "EU Direct deal-extreme" did to me , told me EU warehouse and it took only 7 days. It came from air mail china straight to some house in the Netherlands and then shipped on to me ...I got a warning from the revenue for it. Was not exactly impressed lol.
I think they have something on each product page saying shipped from CN or EU or in this case UK. there must be a warehouse in Portsmouth in the south of england.
I want to buy.

hi can i get the code u use for this project please
II Th3Hawk III Hello I got the code off the internet, just type in ws2812 led arduino code and there may be a page that shows up with adafruit code. i think it was that one i used.
isnt there anyway you would still have the code ?
II Th3Hawk III it may be on my computer at home but I am out at work at the moment.
hi i have followed every step of the tutorial but it doesnt work i use a 2 pin microphone instead of a powerd one so pleas if you can draw the schematics of it and send them you would help me alot i need it for school
II Th3Hawk III Hello, I do not think it will work with the 2 pin microphone because it needs a proper signal level and an unpowered microphone is unable to give that much signal. as for the program I think I found it on adafruit website.
Found the code: forum.arduino.cc/index.php?topic=284371.0
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 .

MIC drawer - funny. :o)
Yes I realised after I had filmed it that that mic drawer was right in the picture :-)
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.
Hi yes I have made several changes to it now. but at the moment im using my only arduino to perform something else. many thanks from Markus
you need more arduino boards ;), i´ve already five here, just to get things running, and everytime something is ready i stick an 328P DIP inside copy the whole thing and solder it on a board...but everytime i tinker around i always want to have a spare UNO board...;) too much unfinished stuff, as i can start just from where i left...it´s the nicest thing with them µCs (but you need to comment your code well, or you won´t be able to read what you´ve done, may be some two weeks later...even worse when more time is inbetween)
Im still new to the arduino. learning new things all the time. I have wasted many hours but those wasted moments will save me time in the future as I hopefully get better.
Get them directly from China, they are like 1-2£ per meter ;)
