- I show You DIY video "How to make 40 levels LED VU METER without using IC".
Don't worry if You don't have electronic skills yet. Just write or show this video into electronic spare-part store shopkeeper when You buy that all components needed, then follow again the step-by-step how to make it on this video when You already in your home.
Sometimes to build the circuit like this we need 4 or more ICs such as LM3914 or LM3915 or LM3916, but not using the IC in this video.

Obrigado, espero que você esteja saudável e sempre bem sucedido.
American guitarist and studio recording engineer here, Love the content, always looking to increase understanding. the concept at 9:05 with the resistor transistor and potentiometer wiper center is super interesting to me, but it seems in general could this project be done way lower volt less resistances? maybe 9 v, but I presume you'd just want to use an IC chip at that point? inspiring work! would love more WHY information and maybe schematics/diagram, link you have a gift here. Thank you!
Welcome friend. For 9:05 it just a very simple driver and convert audio signal to the voltages signal.
Every 1n4148 diode need 0.7 volt to start working, thats why this circuit need minimum main voltage 28 volt so that all LEDs can light up at the maximum peak. If you use 9 volt, so the LEDs that lights up is only up to the 12th LED (9/0.7) when at the maximum peak.
After I've got succeeded making Stereo VU METER-LED with single IC LM3914/5/6 (you can see on my another video), and now I'm in experiment to develope "Peak hold VU METER-LED" with single IC LM3914/5/6.
@@moristo awesome replies man will be following along. Doing my own little DIY kit I purchased here, honestly just worried about the size of the connections I need to solder because I need precision!
Is it SMD electronic component that you purchase?
@@moristo Yes, just worried about my soldering skills but, setting up a nice work station is the first step. I'll let you know how my project turns out.
Love it! Can i use BC 547?
Sure, you can use any NPN transistor, but please pay attention to the EBC pins.
i would like to make this with line level or headphone level. on usb voltage with a normal usb battery pack. do you know a video or a diagram to make it? the american db tracker costs 65 euros lol. if i can build it myself for the half price then im happy
May on my futures video.
Boa tarde professor nesse esquema posso usar leds outro brilho azul
Voce pode usar qualquer cor de 3 volt LEDs.
If a chaser circuit use BD 139/NPN can I use BD140/PNP instead? And do I have to change the circuit?
If you change NPN to PNP, you need to exchange between all Anode and Cathode (including + and - power supply).
Very strong impressive stable VU meter! : D Can I use 12V DC input & have 20 LEDs instead??
Good question, we have to know every 1N4148 diode have minimum 0.62v forward voltage. So to make all LEDs goes light up we have to use minimum Supply voltage with this formula: (Forward voltage x numbers of LED).
I wonder too.
I think that peoples like you know what you have to do.
I would love a similar one like this that respond to bass sounds, can you send me how to make?
Please see my Playlist "VU METER LED CIRCUITS", maybe there is some videos to your liking.
I have a transformer with a bridge rectifier 70 volt DC and i want to vary to voltage from 0- 70volt DC. Can you please advice me how to do it?
Maybe the schematic diagram 0-70v available in google.
Today I dont have 70v transformer.
Do you have a circuit like this one using IC? Probably CD4017/NE555?
Not yet.
Hola buenas tardes
Quería pedirte si se puede un esquema de 30 led pero en stereo por favor si lo tienes
Muchas gracias
Muy bueno esta el video
Richard de Paraguay te saluda
Hola, buenas tardes.
El resto restad 10 LEDs de lo que hay en este video.
Para hacerlo estereo, debes hacer 2 circuitos identicos.
Gracias por tu apoyo.
Olá joaoalves mas o vu só funciona se for com 12 wts???
Assistir para saber.
Will mixed colors work?
I want to use orange and red at the top
Sure you can use it.
By using a capacitor, how can you make the LEDs fade very slowly on and very slowly out and maybe make it adjustable?
Increase capacitor value to make it more slowly. To make it adjustable faster or slowly that will need another potentiometer with special circuit.
@@moristo thank you :)
Hmm, you are welcome.
Can i use 1/4 watt resistors?
1/4 watt it's okay as long as with good quality of resistor.
Mantap bis tolong skemanya bos soalnya vidionya cepat kali😁
Gunakan tombol Play/Pause saat menggambar skema.
Hello, can this circuit be reduced to 50?led increased
You can do an experiment for that.
I have parallel power, can I use this circuit? please
More detail please.
Can i use it for 5v mini amp
Sure, the input audio on this circuit is sensitive.
@@moristo thank you
yaw
You use 1500 ohm resistor can i use 2000 or 1000?
You can use between 1500 - 4700
Hey Morisot, can you please make this 40 LED with IC. IC 4017/555?
I can use 4017 IC for 10 channels vu meter LED.
Low volume pe bhi chalega kya?
yah low volume sanvedanashel hai
If you build with IC will you still use the 40 transistor?
Yes, sure, I will always use all as a needed.
Can blue LEDs be used?
You can use any LED color you like but with the same voltage specify.
Apa yg perlu di adjast @ ditukar apabila lampu led tdk menyala sehingga atas,hanya separuh..sedangkan voleum sdh out buka..tlong ya???
Maaf, pertanyaan seperti ini muncul oleh sebab menonton yang loncat-loncat, sehingga ada informasi dalam video yang terlewatkan.
klw 12 volt 13 pcs led,bisa tdk om?mkasih om..
Rangkaian seperti ini untuk 12 volt bisa sampai 20 LED.
@@moristo
terima kasih om..😊😊😊
mklm om,saya pemula,tpi hobi merakit lampu,moga mkin sukses sj om..
Sama-sama terima kasih dan selalu sukses.
Whit LED 1.5 v is ok?
3 - 6 volt LED.
And which of the videos use the laptop?
Take a look to my video "2 Transistors no IC sensitive VU METER LED"
pakai arus 24 volt bisa normal mohon petunjuk
Tegangan 24 volt, minimal arus 300 mili Ampere (0,3 Ampere). Kalau masih tersisa 2 atau 3 lampu LED terakhir tidak nyala, coba tegangan di naikkan 25 atau sampe 28 volt.
@@moristo trims
Sama-sama.
Can I use 220oms
It's too low.
Hola señor podría facilitarme tu circuito del VU 40 led ❤
He compartido un vídeo de cómo hacer este circuito para todo aquel que quiera tener un VU Meter LED así.
Pake led bening bright gimana
Asalkan LED 3 volt pasti bisa, dan mungkin akan lebih cerah cahayanya.
@@moristo trims
Sama-sama, sukses selalu ya.
Bisa dipasang pada mixer gak bang?
Kalau tau caranya tentu bisa.
30 v dc de a1015 in patlama sorunu ne olabilir
30 volt kullaniyorsaniz tum LED direnclerini 2k2 veya 3k3 ile degistirmeniz gereki
Ada skema rangkaian nya bang....
Yang bisa baca skema otomatis bisa menggambar skema sendiri saat nonton video.
eu acho mais legal aqueles que 1 so acende subindo e descendo....se alguem souber o link manda ai
Talvez você queira dizer DOT MODE VU METER LED.
@@moristo sim eh esse mesmo.....lembro dele de um amplificador potencia que eu tinha e quando dava aquela batida dos graves ele subia e descia....show..
Para isso por favor veja meus outros videos.
20 led e kaç volt kullanabilirim
20 LEDli başka bir videom var
Ky 40 led ke jagah pe 80pics led ka use kr sakte hai same prosess se please reply me sir
Aap ise har star par samaanaantar bana sakate hai hoga 80pics.
Or you can connect the LED in series in every level, so that will use 80 pcs LED.
@@moristo mere pass 250wat ka amplifier hai work to kre ga na 😢
This circuit will work better on the amplifier output minimum 1 watt.
@@moristo really 🙄 sir to aap ek video banaye na 250wat amplifier ke liye uv light maximum 70 led ka please sir😞
Kak, klo lampunya pakai yg 12 volt bisa ? Klo bs komponen mana yang harus dirubah ?
Semua Resistor yang di setiap lampu LED.
@@moristo higher, or lower ohm resistor for 12 to 14v?
resistor ohm yang lebih tinggi, atau lebih rendah untuk 12 hingga 14v?
(Google translation - terjemahan Google)
@@jenntek.101 for 12-14 volt you can use 560 ohm up to 2200 ohm.
24 volt DC or above compolsory for 40 led ???
Each Diode average Breakdown voltage is 0.6v, so for 40 Diodes is 24v (minimum), that's to make till the last on all diodes can works.
@@moristo so, 20 LED is good for 12v.
and each speaker can use 20 LED at 12v?
@@jenntek.101 Sure, each speaker can use 20 LED if you make it like that.
Bng, buatin video kit preamp ampli, bisa?🙏
Bisa, tapi saya tidak mau berjanji sesuatu yang belum tentu saya tepati.
Sya suka dengan jawaban anda bang.
@adityabaladewa3966 Terima kasih.
Audio in ka wire Kaun sa hai
Audio in from speaker.
@@moristo ok
thanks
Can i use a 24v power supply?
Thank you!!!
For 40 LED bulbs you have to use more than 28 volt.
Thank you
Are you Indonesian?
Yes I am.
I finished the 20 led vu meter I followed to your video ,,, thanks for uploading the video, now I have started the 40 led vu meter ... thanks again ,,, I am a filipino here I am in the south korea i have many indonesian friends.....
Pasang di input crossover bisa kah bang?
Kalau di input Pasive crossover bisa, tapi kalau input Active crossover saya belum coba.
@@moristo bosen bng cmn 1 ajh di crossover aktif. Pngin yg gerak2🤣🤣🤣
Silahkan bereksperimen, semoga berhasil.
Can you share diagram
I don't have it yet till today, but you can draw it yourself right!
Interesting that the meter only responds to the bass frequencies and not the whole audio spectrum?
The signal input I connect to my subwoofer as I have shown in my previous videos, so only bass voice will take effect to the LED light movements.
Pesen satu mas
@didaroyani3233 maaf, saya belum jualan ginian.
Can a 24V/1A power supply be used?
Yes sure, you can use it.
This is linear scale?
@@Lamster66 You need a calibration tool to know the scale between the number of LED that light up and the sound power.
@@moristo Thanks, Not sure if you misunderstood my question or that I just worded it badly.
I wasn't talking about the full scale deflection I meant the steps For example if I wanted 0db to be LED30 and the voltage is say 1V (It would actually be 0.775v for line level) then 0.03V will light the 1st LED and increasing the Voltage by 0.03v will light each LED in turn. That would be Linear i'm assuming all the resistors to the LEDs are limiting resistors and as all the others going to the transistors are the same value the scale will be linear, or that the same increase in voltage will light the next LED? opposed to Logarithmic where each step is say 3db which would require different value resistors at each step and a doubling of voltage at each step. You can still scale it so that LED 30 comes on at 1V the difference is that to light Led 29 takes 0.5V rather that 0.97V and LED 31 will take 2Volts rather than 1.03V.
So when you say calibration tool where you meaning a meter to measure the voltage to then adjust FSD or did you mean a Log scale calculation to work out the correct resistor steps for 3db increase?
Anyway the video is very good and It's a pretty cool way of making an LED VU meter.. I was also impressed with you soldering skills (or moreover your component bending skill) it's not easy to make something like that without a PCB and have it robust enough to handle it without either shorting out or falling to pieces.
I was just interested as I want to make 32 of these for a 32track meter bridge. I'm just trying to work out would the cost of 40 transistors and 40 scaling resistors be less than 4x 3915n bought from china at $1for 5? Also with the chip method you get dot mode option. Either way it will be expensive as I'll need around 1500 LEDs or 150 10 segment bargraph modules and a hefty PSU. Not to mention PCBs, other descrete components and an enclosure (which I'll have to make.) I guess the other way to do it would be to use the 4x 3915n chips and multiplex them between 2, 3or 4 channels but again there the cost of the multiplexing ICs and you're still going to need a good PSU.
@@Lamster66 Based on your comment I feel that you know about the forward voltage of a diode, so I think you know abaut how much voltage for each LED step to light up. The resistor at each transistor base will limit the peak base to emitter voltage in each transistor.
For a comparison of total component prices between using IC and Transistor, you can find out yourself based to the component price on the marketplace.
Please see my video Dot & Bar mode VU Mtr LED without IC.
Bro my first 2 led already on how solve it
For class D amplifier you have to use more audio filter for the amplifier output so the LO frequency (around 300kHz) can't interfering.
@@moristo yes my amplifier is pam8304
Good.
Deixa o Diagrama do circuito.
Eu faço meus vídeos para todos, mesmo sem conhecimentos de eletrônica (veja meu canal "sobre"). Na verdade, o diagrama do circuito não é mais importante do que o próprio circuito; diagramas de circuitos são necessários apenas para aqueles com habilidades eletrônicas. Por outro lado, aqueles com habilidades eletrônicas podem desenhar diagramas de circuitos por conta própria.
connected directly to the laptop, is it possible?
Depends to the laptop's earphone output.
@@moristo Laptop's earphone output is 0.2 - 0.7V. Connected directly to the laptop, is it possible?
On my laptop it works, just try to know on yours!
Can i use BD 139 instead of C1815, for the signal from the laptop ?
You can use any NPN Transistors, but please pay attention to the EBC pin positions.
Input dari speaker atau dari sinyal audio bang
Sinyal audio dari HP atau laptop bisa, dari speaker juga bisa.
Bisa minta nomor WA bang
Maaf privasi khusus keluarga aja.
Waduh..
Gini bang aku mau pesan bisa kan
Kalok nggak gini minta fb aja bang biar aku bisa kirim foto
Led nya jenis apa mas? Soalnya sekarang rata² led nya sangat terang jadi kurang cocok buat vu meter..
LED biasa yang 3 volt, diameter 3mm atau yang 5mm, banyak di jual di pasaran, kecuali di planet Mars dll belum ada yang jual.
@@moristo iya mas, maksudnya kan kebanyakan yang 3mm sangat terang, beda dengan yang di mixer build up..
Yang seperti di mixer build-up jg banyak di jual.
bang punya saya nyalanya,metok di led 20?
Mungkin ada yang salah atau mungkin ada keterangan dalam video yang kamu lewati.
@@moristo kesalahanya di r 4k7,saya pake 33k
Nanti perhatikan dengan seksama keseluruhan video agar tidak ada perbedaan dengan yang kamu buat.
For 2 vumeters (stereo), how much should the supply voltage be?
Just the same.
Tanpa IC apa tahan lama ngab
Kalau pakai komponen asli pasti akan tahan lama.
এটা কত ভোল্টেজে চলবে
वीडियो में जो है उसके अनुसार
ada lampu 1 nyala terus ngk mau mati yg lain normal nyala ngikutin input
Kemungkinan Transistornya LED yang nyala terus itu jebol/koslet.
aq kasih max 30volt masih kurang 4 lampu yg kuat nyala kak
Kualitas LED yang kurang baik, kalau LED yang seperti itu sebaiknya nilai Resistor setiap LED di naikkan 3k3.
Maaf masbro, kamu jadi terdeteksi spam oleh sistem.
@@moristo panasnya agak ngeri juga y kak
Warum geht das alles so schnell das kann man als Anfänger nicht erkennen . Schade

Danke fürs Zuschauen.
aq buat kok cuma nyala setengah doang ya kak padalah udah sama persis dengan ini
Rata-rata yang tidak menyimak secara lengkap dengan seksama, hasilnya akan seperti itu.
@@moristo apa karna 12 5@ y
Aduh aku khawatir salah tafsir maksud kamu, bedanya dengan yang divideo apanya.
semua kan sama dari segi komponen cuma aq suplay 12 volt 5 amper ..
Nah, dalam rangkaian elektronik kalau ada perbedaan apapun, itu artinya tidak "sama persis".
Muito bom
Obrigado.
