Very well explained, please upload a video with more led for DIY UV meter

Nice,,and excellent video bro

wow good work. thank you

Good job guys.

Mast hai bhai

Thank you very much!

Samjaneka tarika bhout hi sundor tha

Intex ka woofer Mai Kam karega ye

Sir jha apne spst switch lagaya wha per koi be push button on off lagg sakta hai kya?

Nice work

50 sek. Schemat masz dla lm 3914. To jest to samo?

No projeto feito no vídeo você usou o IC 3914, e no título está o 3915.

I've made the same circuit and it works like a charm 😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊

Mere vu metar ke connection Galt jod gaye the audio input wire mai mene Plus de diya tha battery ka jisse khraab ho gaya kya kare ic kharab hoa ya kuch or please reply

Sir Dil sa thanku

nice video

Sir 4440 ic amplifier pe kaise lgaye .. Ap kehte hai 3.7 input deni hai vu meter ko..

Ic ka 9 number pin ko led ke plus bale pin main jor daen Kaya??

Bhai 4.7k preset ke jaga agar 10k lagay to kuch problem hoga?

Audio signal ka negative wire kaha par lagata hai

500 & 1000watt amplifier me vu meter lagane ke liye konsi ic use kare please tell me sir

Sir can i used 5k preset insted of 4.7k

Can i use this vu meter for tpa3116d2. On 50 watt output

In the circuit diagram there is mono input , If we want to give stereo input then how connect with IC...

Can u make layout .Just like amp 100 watt plz

kaha se ho

ऑडियो input से चलेगा क्या

My ic not working properly . When I Connect with 9v Battery Then just On 1st led . What the problem and Get This Solution.

Good afternoon, can I use the 3915 in this project?

Can I use 10k preset ?

Bhai mere pas 560 ohm ka resistor nahi hai uske badle me kitne ohm ka resistor lagaye

Is me peak holder nahi he?

Fine

Good

SPST switch na lagaye to koi dikkat hoga...

Sir 1.5k bajay 1 k rejiestor lagasakta hai kay

Sir 2n3773 circuit board 18-0-18 5 amp transformer laga sakte hai?

Bhai 560 ohm ki jagh dusri kitne ohm ki lagaye

Led ka mm kitna hey

3915 ic circuit er 1 ta video upload korun plz

How I increase led

Maine 3915 ic se banaya. Magar audio k hisab se Nehi chal raha hay. Agar potentiometer ghuma raha hay to sab led on ho ja raha hay. Solution bataye please.

5 v diye chalano jabe na?

Vu meter ko 3055 me ka6e connect kare...??

Vai eia ic khapar milaga

Is it safe to attach on 50W+50W STK amplifier, if not what will be the solution?

Microphone circuit up to 3.7 v semnal ! Please show me how, please ! Your video is super ,you are great! Electret microphone ,semnal infirm.

20 led ka banana ho to konsi IC use karoge...20 led ka banana batao...nice video..👍

Sirji mobile sa input karsakta hai kay please reply me

Sir vu meter ko kaise 3000w amplifier me lagaye

Sir tda 7294 ic pe ek video banao na plz

Sir circuit degram milega

Çok güzel 👏 👏 AYRICA devre şemasınıda yayınlarsaniz daha güzel olurdu. Thank you

Bhai kuch jankaari leni thi k jaise 1000 watt amp me vu meter lagane k liye supply 24 volt ki jayegi ya 12 volt ki ur agr 24 volt se b jayegi to wo 24 volt hum oaha se lenge alag se trnsformer lagaye ta power stage se supply de poori jaankaari de bhai ur us pe ek vedio b banye jis se hum logo ko achi jaankaari mil sake

Can we use this circuit on any amplifier board?

150+150 watt amplifier ka Liya ek banya na muja banana hia

Good job.. how can I use microphone for input instead of wire...?

Sr Tda 7294 par video banjo na plz

Hallo sir miximom kitna led use karsaketea hea diteles batayea pl

Good video 👍 👍👍👌 👌

Sir ji 2 ic lm3914 kasa joined kara

1.5k resistor nhi mil raha koi dusra use kar sakte hai

Sir ishka pcb layout banayiye....

Sir while you showing in parctical of this vu-meter ... few connection is different from given circuit diagram... So ,i want to known that if i do this circuit that what are you doing it will be correct or not ?

भाई ये vu मीटर सभी amplifier बोर्ड मे लगजायेगा

Com o IC LM 3915, é a mesma ligação?

Sar ji eska pdf nahi hai kya

Sir me kya is vu meeter ko 4440 ic board me connect kar sakta hun

Sir please upload a video on diy amplifier circuit board

3915 ic you's kar Sakta he

Please give a Video on " volumn, trable,bass,mic,echo "all in one in one pcb board. With pcb layout.

Bro it doesn't work when I connect to amplifier the led is off

Bhaiya 3915 ic yaha pe nahi milta hai aap dusre ic pe banao

4440 ic amplifier me laga sakte hai vu meter 100 watt amplifier 4440 ic me piz... piz... repli me

3914 ki jaga 3915 lagasaktahe

4440 ic ma kasa connect kara

Is ic ke jagaha par 3915 nhi lag sakta hai

Sir STK amplifier se audio Keyis nikalo PZ help

Muje trai karna padega

Dada 11 led hone se kaise connected kare app to 10 led ka dekhaye please 11 led ka dekhaiye

Give diagram on this connection

No dat mode

Ic number

Pilij aapka mo... Dijiye sar muje odar dena he

Time number to daya jabe .

1k hoga 1.5 k nhi hai

Input kaha thik sha samjata nehi jaldi krdya

Fack hai nehi ho raha

चलता ही नहीं है पागल बना रहा है
