Sir will it work with bc548 transistor 🙏 please reply
does the project work for 24 volts ??
No
Circuit diagram link is in the description box.
Ghuma fira k yeh ek ic he hai....ic me v transistor he hota he.. 😆😆.
But appreciate your work..♥️

Very nice
Nice bro
U make a fm circuit which can be operated by BC 547
Nice video sir ye jo resistor lagaya hai value kai pata kare. Reply sir reply
Please describe properly your words.
I did not understand what you said.
Hi, I have a few questions if you could help out with these please...
1) what's the max input voltage this circuit will work on (I wanted to 9v or 12v psu 1.5a / 2a)?
2) What is the maximum number of LED's per channel this circuit will allow (I wanted to use upto 30-40 per channel)?
and finally 3) If I wanted to have a completely ON/Static function (eg they flash so fast that they appear static/on), how could this be achieved?
Thank you in advance (",)
I haven't the schematic, but for what I have seen, there isn't any "base protection" so you cant exceed 6V that is the maximum base voltage (VBE) for the BC547. Instead the maximum number of led that you can put in parallel is limitated to the maximum collector current (Ic) of the BC547, that is about 800mA, so teorically you can put 80 LED in parallel foreach channel, teorically because the thermical drift could destroy all your LEDs, so pay attention, or change the circuit.
Kya hum ise 100 led pe chal sakte hai. Ans. Please
Yes you can.
But you should use relay like this - ua-cam.com/video/-MbalfqFifk/v-deo.html
Yes 😊👍
How much dc votage we can give this circuit .
Because im planing to make led chaser star using ur idea.
But i had 60 leds 3 × 20 .
Im thinking ac to dc simple converter to power up these led's
Will it burn ur circuit
Can u suggest better way to make my idea possible...
Hope you replay soon
You should watch this video - ua-cam.com/video/-MbalfqFifk/v-deo.html
@@estechknowledge thx bro
Please show circuit diagram
Circuit diagram will be available after 30 likes on this video.
Super no free
How many LEDs can we connect to this circuit?
Watch this video ( ua-cam.com/video/-MbalfqFifk/v-deo.html ) to connect 1,000 LED on this circuit.
can we increase the speed using potentiometer??u only showed to slow down only
Yes.
I would suggest 100k Potentiometer for this project.
Sir kiya ap AK Sawal ka jawab day sakty ho
Smd led 1 ya 2 kharab ho gai about hum same smd led laga b dain tou 2 say 3 din led balaf kuin kharab ho jata Hai.
This might be the high voltage problem. You should decrease the voltage a bit.
Awesome my Friend, Well Done
Nice sir ji
Ye pilet kitane rs. Me ban ke teyar ho jati h
bisa menggunakan baterai 9 volt?
Ye sab kaha par milta h
अगर led की संख्या बढ़ानी हो तो क्या सरर्किट मे कोई चेंज करना बढ़ेगा.....?

Resistors ki velu 4.5,1.2,10.15 koms hai. Reply sir. VALU SAMAJ ME NAHI AATI.
Resistor ki
So you are asking why I had not shown the actual value of resistor.
Every one does not have the similar value resistor. So I had shown a perfect workable value of resistor.
I hope you understood.
Is circuit mai kitna led lagayenge
The LEDs that I had used consumes very low energy. If you are using this type of LEDs then you can put about 3x20 LEDs on the circuit.
Circuit diagram chahiyen
It is available on the description of the video
100 se jada led ke lie same circuit chalega ?
usme kya kya component jada lagane chahie ..
Reverse chalane ke lie kya kre...thanx
You have to use relay for 100 LEDs
@@estechknowledge thanx ..but relay kaise use kare ...koi circuit ya video ?
I will try to upload a video soon.
Sir 4-5 ke resistance nahi mila karpaya bataye
I was wondering if anyone can help me please. I've built the circuit using R1-R3 4.7k, R4-R9 1.5k, R10-R12 10K and R13 as is but also with 100K as suggested in the comments.
Although the circuit works and I can see the LEDs fade a little while cycling through, they don't go out completely like in the video.
Could anyone advise what I've done wrong or what I'm missing? I suspect it might be the resistor values and maybe I should use higher ones, but would really appreciate it of anyone here could help out as I'm not an expert in this field.
Thank you in advance and once again I would really appreciate your help on this. (",)
Use 47uF capacitors, use R1, R2, R3 = 10K, use R7, R8, R9 = 1-5K and use R10, R11, R12 = 20-50K
And can you say what you are using for power supply.
ES tech knowledge , hi, thanks for the reply, I’m using usb power at the moment 5v as I’ve not got a 4v supply. Ideally I’d like to power off a 12v or 9v if possible as these adaptors are common in the UK market.
But yes I will certainly try as you have said unless you have other suggestions depending on the power supply?
Thank you 😊
I think you should watch this video for 12V power supply.
ES tech knowledge, sorry I don’t see the video link ?
