Hi.. Thanks for the circuit.. It's really great circuit.. In the video you told connecting two emmiters of the transistors and you actually connected the emitter with collector of the second transistor.
Yes there's a mistake in caption 3:06 . connect Emitter with Collector. comment pinned.
Cap
to be honest 3:06 to 5:58 are all wrong to be honest (the first capacitor connected to collector ) when it is connected to emitter.
I cannot follow it’s so confusing. Which is the 2nd transistor? All of the video from 3:06 is wrong :(

Adding an beeper to sync with leds along circuit diagram could be icing on the cake!
Thanks for the circuit I was desperately searching for this circuit
This circuit is very educational because we get to work through your mistakes.
You are the best breadboard layout person that I have come I am just learning how to do this and it's really hard to make mistakes watching you
Thanks for this circuit. I was desperately searching for this circuit
You are welcome
Good Video! but what is the wire you put here 1:35? thank you for your answer.
THAT rotary plate at the end, I'm dying xD xD xD ... what a simple solution :D
:D
Where can I get a circuit diagram
... it's a very very simple diagram
Made this as my first elektronica project with a bit other components and it worked from thé first time. Happy as a 53y old kid😂😂😂
Now I read that thé video is wrong but mine works🤷
Hi question?. What type of resistor can also be used? Because i dont have a 470 ohm resistor. Is there another type of resistor i could use besides a 470 ohm resistor? Also i have a 10k resistor i only need a diffirent type of resistor that i could also use besides a 470 ohm resistor, plsss answer!!!
Is this a SR latch version of flip flop or something else?
great video now to see if I have all the parts to make the circuit
Good luck!
Can i use a 470μF capacitor?
After doing 3 different tutorials from 3 different youtubers, this is the first one that actually worked for me. I would love to see a video that explains the logic behind this. What actually happens when and how.
thank you! and stay tuned, more will come
Cap
There's much better videos than this out there. Keep searching.
Thanks.It works!!
problem solved,works great.
Thankyou!
is there a way to add a time delay between the blinking of both led
Lights turn on, but do not blink. Using 330 resistors with the 10. will this make a difference?
Excellent, thanks bro😊😊👍
Thankyou!
Nice one bro thxks I have built this with your video
Great 👍
it works with 2n2222 transistors too! thx for showing us
you're welcome
One light blinked but honestly haha these instructions were a little complicated for me, but I’ll try again
Thanks man it's really work 👍👍
You're Welcome 👍
It was nice and simply project... In this experiment we have to prepare the report bro...... Just three page need... Kindly help us... what is use of this and some introduction about this and etc....
If you take note of where the connections are or go, and ignore the captions which tell or give the wrong information, you should be able to get it to work as I have.
that's why I pinned a comment in order to correct the mistake in video.
Finally achieved this blinking light. Though one light stays on longer than the other.
How many of here for collage projects 😁
best of luck
Here for a high school project
I am here just to complete the task my uncle gave me 5 months ago that I forgot about
I’m here because I’m bored
Never went to college
You said connect both emmiters and you connected the emitter to the collector of the second transistor that's why mine does not work. Now is this do as I do or do as I say?
I'd be lying if I said I didn't nearly cry when I got this to work. Time to figure out how to string a whole whack of these instead of just two
Dude you’re crazy you might as well make a microprocessor instead. You could wire billions of these togethers and you’d have a real microprocessor with real programmable computer logic but you’d need an understanding of registry’s, memory, etc. By then what would be the point. Just use a CAD program and design a chip and check out Sam Zoloof’s channel for photolithography.
Lol when I did this two years ago, this was the first time I’d ever even seen a breadboard. I don’t know if I even know what a microprocessor was 😂
It was for an assignment I had in college. But good to know!
Did it on fritzing and a capacitor exploded. What can the solution be?
It Works thank you
You're welcome!
Isn’t this the Astable Multivibrator circuit?
thank you very much... this video helpful.. may I ask the schematic flip flop circuit ?
you're welcome
Pls explain me how to design a circuit diagram. Actually i dont know how the put resitive and inductive value.
In this video: th-cam.com/video/pxfkcfNggqI/w-d-xo.html you'll learn this.
May I can use 220 ohm resistor instead of 470
yes.
Yo probe agregarle dos led mas, entre el colector y el negativo y en el emisor del otro transistor para indicar cuando abren los transistores, funciona
thank you so much for the video.. it's really great but can you share the circuit diagram?
Bro liked it but didnt give schematic
Wish you explain how it works. I can easily follow these steps but i won't learn anything.
I also need proper explanations
Thanks Bro
Welcome
Any 100uf capacitor use
Nice vid. Can 1 transistor be used to make 1 led blink on and off? How?
yes checkout my channel I had made a video on this topic
No you need two transistors for continuous blinking.
Thanks man
You're welcome!
Thx mate
Thank you❤🌹🙏
Welcome 😊
LED 3V or 5V or other?
Thank you so much i can niw be smarter than my grade 5 classmates
you're welcome
can I use transistors other than the 50V 100Micro? I've only got 25V for it and its not blinking
transistor or capacitor?
Does this actually work? I'm choosing between this or the 555 ic one I want something that's easy so I could submit it in a couple of days
Yes
I really love this video but i got many difficulties making it because i was using c945 transistors but it is actually the first video that worked on my bread board thanks very much......❤❤❤
Best of luck for your future projects
How 10mm LED instead of 5 mm LED ?
Do I need to change the associated material value?
no
3:38 - Are you connecting to the Transistor Collector or Emitter?
Is it just me or are you referencing collector as emitter and vise versa? The order from left to right of a BC547 NPN Transistor is Collector, Base, Emitter considering the flat side is facing you.
If I'm wrong then please correct me.
kindly read pinned comment
Your not wrong it was going so well till the end then he started making mistakes I followed what he did not what he said and it doesn't work either way this is getting annoying if he would just give us a damn schematic.
The circuit does not work ifmyoumfoolow,the instructions you text
Very nice and clean vid well done ,.//.,
Thankyou❤
alternative Transistor BC547 thanks
Thankyou!
Hi can you share the shematic? Please
im confused when you connect both emitter but each of them are in the opposite side of the transistor?
read pinned comment
It appeared to me that in the video the collector of the transistor on the left is connected to the emitter of the transistor on the right.
can i use alternative resistor, instead of 47O i use 1OO? or 33O
yes you can use the most nearby value available.
@@IdeasTv thank you il try it out
Will this work with a 2n 2222a transistor. Its all I have for now
It worked. I did not have a 9v supply though so I used 100ohm r in place of the 330
Kala ko yung 10k na resistor nasa base ng transistor? Diba laging sa huli yung base kasi e c b ? Tas sa gitna nya nilagay yung paa ng 10k resistor so collector yun? Kasi sabe connect the resistor to the base ?????
"Thank GOD" 🙏🏾, and thank you very much for sharing your support and time 😉 PLEASE provide a circuit diagram 👍🏿
you're welcome
Can we use bc109 for bc 547?
yes
What that function of capacitors this cicuirt
What's wrong with the circuit if only one led light turns on?
recheck your connections and read pinned comment
It work !
Would this work if I use a 220 k instead of 470 ????
The 470 ohm resistor is to limit LED current. 220,000 ohms might be too much.
Does it need a same color of LEDs?
not necessary
He gets a some nice flashing lights I get a 3 degree burn from my transistor
I got it to work but it didn't flash, brand new to this so I don't have a clue what went wrong.
You connected the emmiter to the collector whats up
Schematics?
Bro how can we keep more LEDs in led
Just add LEDs in parallel combination.
I dont have bc547 transistors, what can I use instead?
2N3904 works.but pinout different. 2N3904 = E B C (flat side facing you) and BC 547 = C B E . 2N3904 is very cheap too.
Can I use other amount of resistor?
tell me the values of resistors that you have and wanted to use?
Will a 2n2222 transistor work instead of a bc547?
Probably but the pinout is different.
@@richardl6751 oh ok thx for the info!
Can I use 220 ohms instead of 10k ohms resistor
no
Yes
This ckt is kind of unbalanced cuz the duty cycle of one led is longer
May I know the schematic diagram pls.
Can u guys plz post a schematic.
Hello
If left led run which capacitor is connected
I didn't understand your question
@@IdeasTv hello how to make johnson counter
My capacitors are too small. They are tiny compared to yours here. Only one led blinks really fast; the other just stays on. I need the ones you are using. Drag.
select capacitors by value, not by size
@@IdeasTv Hi, I've been into computer programming, since I ever knew what a computer was, but now, I'm a much older man, and I'm doing Breadboard Electronics with the Raspberry Pi and Python programming with it. You're video showed me how capacitors work, in conjunction with the Two Transistors. You explained it perfect. My two capacitors were very small in size, but the same style yours were, but ten times smaller. Only one light would blink very fast, because of the natural timing of the capacitor dumping back into the other light, so it couldn't blink at all, because even yours had a bit of a difference in the back and forth blinks of the two lights, one blinked a bit faster than the other, when viewing them going back and forth. But you taught me what the capacitors do, and I had also learned that transistors block out noise, like a switch. I don't have enough of them to make my 24 bit binary Led dance, so I'm going to see noise from the other LEDs, but I'm going to show beginner Pi users how to create a Binary Beat program with Python and a Breadboard with lots of whatever colour LEDS one wants to use tok go right nuts on the RPi 4 with me. Check out some of my videos on it, I show all my progress on how I learned to make things with it and show others, how it's not that hard to learn. I'm teaching it, while I'm still learning it myself. I've only been into it for about 7 months now. I have much to learn with electronics in full general, I'm not anywhere close to your Genius yet, but I'm 57, I've been soaking the RPi up pretty heavy though. Please take a look at my latest video on Fun with three 74HC595 shift registers. I learned everything from you BRIGHT PEOPLE. Everything is from you guys helping us all. YOU!!!! xox Thank YOU xox
can i have a circuit diagram of this circuit pls
repetitive music usually drives me crazy but for some reason, I liked this music.
Bro u are connecting the collocter to the emmiter and emmiter to the capistor positive
Transistor used in this circuit is NPN or PNP pls help me
NPN
whats is the exact value of the capacitor ? they dont understand 100uf !
msg me on IdeasTV's official facebook page, i'll send you the clear picture of capacitor
Hi bro may I know the total cost of all the apparatus
Can I use any color? (LED)
yes
How is the emiter in one tranzistor the other way than the other iam so much confused
have a look at pinned comment.
Are the resistors necessary?
yes
Can it works with 24vDC?
No 9V - 12V max
I think you can by using a 3.3k resistance in series with main supply
What is the price of these all components? Tell me fast Bhai..
hi what happens if both LED"s only light up, the two doesn't blink, help pls
re-check your connections
In this which flip flop used jk / Sr/ d???
sorry, can't understand your question ?
I did the steps but its not working , it took me 3 hours to repeat the process and still nothing happens ,
I thought everything will be good ,
is it okay to use different transistor?
no
Doesn't work! I took all the same components but only the left led lights up and the right one is off and it doesn't even flash
Please help! I literally have to submit it tomorrow
Check pinned comment
Can I replace the 470 Ohm Resistor By Other One
yes but close value
I have a 220 Ohm Resistor Can I Use It Instead Of 470 Ohm Resistor
can we use any transistor make this circuit
you can use any NPN transistor
Does anyone know if its a 16 volt Capacitor?
yes
@@IdeasTv thank-you
Can I use 8.4v battery?
yes
