- High Quality LED Flasher Using BC547 NPN Transistor | LED Flasher | Javier's DIY
An LED flasher circuit is a circuit which flashes the LED- meaning turns it ON-OFF, ON-OFF, ON-OFF.
The BC547 is a NPN transistor meaning when power is applied to the base (control pin) it will flow from the collector to the emitter. Typically NPN transistors are used to “switch ground” on a device, meaning, they are placed after the load in a circuit.
Component's Needed:
🔴 2x BC547 NPN transistor
🔴 2x 10v 470uf capacitor
🔴 2x 10K ohm Resistor
🔴 Insulated wires
🔴 Copper wire .1mm
🔴 5x LED Blue lights
🔴 5x LED Red lights
🔴 4.2VDC input

Thank you so much for making this.
Thank you sir. Welcome
Thanks for the simple and easy project, I've given it a try and it works, except for the manipulation I do on the bulbs
Thank you sir.
Nice👍👍👍
Thank you sir
Nice work
Thank you sir
Thanks bro it is working
Thank you sir
Why do you make videos with background music, you could have explained the working of the circuit both on circuit diagram and final wiring. Popups are overlapping the circuit diagram. You can share the circuit diagram in description also.
the particular circuit diagram sir is very easy to follow, just watch it
I absolutely HATE music in videos like these. I would rather hear the ambient sounds of construction.
Very very nice
Thank you
Good
Watching from Ormoc City
Thank you sir.

सर यह ट्रांसफॉमरलेस सप्लाई से नहीं चलता
Genial idea, yo lo hice como en el vídeo solo reemplace los LED por unos módulos de 12v, aunmmente el voltaje me funciono muy bien
for better understanding please use the universal language
Excuse me, how to make a multiple leds using a 3v power supply? Like 4 to 8 leds. I am gonna make a left, right and hazzard lights to my model kit.
😊 Grazie funziona
For better understanding please use the universal language
Nice project, already like and subcribe brother
Awesome Video.
How can I use this circuit for 12V DC power supply?
You need to have an IC to lower the voltage it might burn if you supply 12vDC
👍👍👍👍👍
⭐⭐⭐⭐⭐
Great Work! Super!
Thank you sir
Hi Javier! First I wanna thank you for sharing this circuit with all of us. You just help me here in Brazil. So, I gotta a question: Can I use a 5 V source to supply?
Yes sir. But be sure to put a 100 ohm resistor in series to the positive input
@@JaviersDIY sir please send circuit diagram of this circuit
the circuit drawing is on the video itself sir.
How can we connect double nos. Of led with this circuit?
Has anyone used 2 transistors AC 128 to make an astable multivibrator known as Flip-Flop with 2 100uf electrolysis capacitors ,2 10 I resistors and 6v bulbs?
Hello there. Would 470 microfarads be a 10 volt capacitor?
No.
@@JaviersDIY Ah. you are using the same. sorry
Sir can i use 470 uf 25v capacitor?
Yes sir you can use that one but the interval of the light to blink will be change
Excuse me, you have on different position the capacitors in your diagram, If you compare with your proyect, one has the positve to the transistor and the other one has tha negative to the transistor, what's it wrong?
No sir.
I am sorry, but I can see the symbol of the capacitor is with negative side to the transistor in your diagram, your circuit is working very well, but the diagram is invested the positive and negative poles. It's just an observation. Thanks for your time and share your knowdlege.
Can I use 20 led & 6 v dc this componments
Yes sir
@@JaviersDIY thanx sr solv my problem plz sr daigram Or mil jata to meharbani hogi
Sorry, is it possible to use 220 volt electricity? If it doesn't work, what components should be replaced? Thanks
It is not good if you directly supply a 220VAC , you need to have a module that has an output of 5v.
@@JaviersDIY thanks for the answer... but is it possible if the Elco is replaced with a 50v 470 micro and the resistor is replaced with a 100k... to connect to 220v electricity... sorry if I'm wrong, I'm a beginner who still has a lot to learn and ask those who already have it. skilled like mister.. thank you
no sir that's not possible
@@JaviersDIY Thank you.. At first I thought maybe I could replace the Elco, add a diode to the resistor, but with your answer, I didn't dare to try it.. Once again, thank you very much.. I wish you more success and progress.
@@JaviersDIY sorry sir. I have a 100k resistor and a 50v 470 micro Elco, can it be used to try the circuit like in the video sir? thanks in advance
sir, sorry in advance...I'm a beginner who wants to learn and try...I have a 100k resistor, IN 4007 diode, 50v 470micro Elco and BC 547 transistor...can I make a circuit like in your video but with a PLN 220v voltage... Please guide me and wish you success
sir, 220V is a very high input voltage. The circuit only operates within 3.7-5v sir.
Sorry sir... I want to ask, is it possible to add up to 10 right and 10 left LEDs if there are any components that need to be replaced... thank you in advance... good luck
yes you can put 10 LED every channel sir. There is no need to add some components
@@JaviersDIY Thank you sir...for your knowledge and guidance...best wishes always

Can l use 25v 470uf capacitor instead of 10v 470uf capacitor??
Yes sir. You van use that one but be expect to have a slower flash of the light
@@JaviersDIY thank you, but will l use 1 or 2 capacitors as shown in this case??
Please reply sir
Yes sir
Thank you
is it okay if ill use 9v DC sir?
No sir
can you load the circuit diagram.. in video is not clear due to obstructions....

How to control flashing speed
It is better to use a potentiometer to control the flashing speed
I have tried but the light is not blinking,l used a 16v 470uf capacitor instead of 10v 470 uf capacitor but still it is not blinking
Please reply sir
Maybe you have a wrong connection sir. That circuit that I have is working properly
But l have made it by seeing every step in the mobile, just the capacitor was of 16v 470 uf instead of 10v 470uf. Then?
Please make a solution for me sir, please
Try to use the capacity what is on the video
sorry, I made it and it worked. like in the video sir... but if you replace the LED with blue and green it won't turn on... why... even though you tested the LEDs one by one, they all come on, but if you put them in a circuit they won't turn on... there's a problem. where is it... thanks in advance for guidance
voltages is dependent on the color of the LED sir, meaning every colors of the LED have a exact value of input voltage.
@@JaviersDIY Thank you for your knowledge, sir..I used a 5 volt output adapter as you suggested some time ago..the problem is, if I use red and yellow LEDs, they all flash normally like in the video, sir..but if I use BLUE and GREEN LEDs, why doesn't it work? turns on... even though the LEDs are tested one by one they come on. What should I do sir, please guide me. Thank you
it is better to put a transparent LED with different color because that has a high input voltage around 3V up
@@JaviersDIY Thank you sir.. I have used 5 volt power, with the same circuit as in your video, I used 4 LEDs on each path (4 left) and (4 right) the difference is that I used 4 colors per path, namely the left path: red-blue - yellow-green and right lane: red-yellow-blue-green. The problem is that the normal light is flickering like in the video sir, only the red and yellow ones are in each lane... the blue and green are off (not on) even though they were tested one by one with all the multimeters. it's on.. why, sir? What do you think is the cause? Please guide, thank you
yes sir that's correct but as what I have mention earlier, the input voltage of that LED is dependent on the color and quality sir. For example the color red LED has a support voltage of 2.5v maximum while the color blue LED has 3-4V that can support meaning it has a big comparison with the color. I suggest just use the same color
