You made the drawing yourself ? They seem really nice.
555 comments i dont want to ruin it
Finally someone explain that the capacitor is the key for changing the output state in the astable mode, other videos just throw formulas at your face and just skip the key of the thing with some "you just suppose to know that" vibes, what a shame.
Appreciate it!
This year 555 Timer is celebrating its 50th birthday, my congratulations. Half a century in electronics is all eternity.
Explaining how it works great done. 👍(ツ)❤️
This actually made me feel like I understand electronics and will allow me to understand what pins what and what the 555 does and how it does it for my A level studies, thanks a lot!
This is the best description of a 555 timer I've found so far. I'm learning this stuff and your video was really helpful. Thanks!
I had to slow the playback to 0.75 and it gave me a greater amount of time to absorb this information. I'm a noob. But this stuff is fascinating, I can't think of any other word for it. Sir you are an excellent teacher. Thank you.
The best explanation of 555 timer...
yea when you already know what he is talking about , then again you don't need much explanation don't you ?
That guy is an idiot, he described the chip for 10 minutes without even saying what it is about and or what he is talking about.
PURE RUBISH
@@michgingras Where's your amazing content?
@@michgingras something tells me you cut yourself.
@@THE16THPHANTOM I didn't know how it works and now I do. You being slow to understand doesn't mean the guy did a bad video, it just means you're slow.
@@furrane
OK, boomer.
this has to be the best explanation of 555 timer ever, the internet needs more vids like this. I need to find the DC motor control tutorial referenced towards the end of this video
That was one of the best 555 tutorials I've seen in ages, and the graphics both on the chip and at the right side made all the difference to helping understand it... Thank you so much!
The best explanation about the 555 I have seen so far, and with the graphic animation that is simply wonderful, my sincere congratulations. Shared
That is the best explanation of the 555 that I have seen yet.
Although I was already familiar with the 555 timer IC, I liked your presentation. Clear and concise.
Also, congratulations on your English. I wish that I could speak a second language as well as you do.
Kevin Byrne - congrats are - extremely - premature. Really, pal, why would you say this? He is very difficult to understand now and of you tell him he is “great” talking english, he might STOP trying to improve. In this way you actually HURT his progress.
This guy has very good content and the right ideas about teaching, but still need to improve English
A LOT.
@@ShelliLoop wow you're stupid af.
S H i agree, the English is shoddy and needs work.
I agree with Kevin. I already knew most of this, but it is an excellent video. The 555 timer is a "killer app" example of an integrated circuit. It's simple, elegant, and versatile!
The criticisms of his English are unfounded. His English is very good. His accent is still very strong, but I had no trouble understanding him. Accents only go away with time and exposure to native speakers, which not everyone has access to.
@@jovetj yup, the 555 timer, along with a 566 chip, form the sound of the 2 flying saucers on Atari arcade Asteroids. It really is used in a ton of stuff.
Every" band " needs a drummer. ( 555) And this is good way to" educate " folks tks for the Good show.
HOLY CRAP. The 555 timer is still around ! Amazing. I was using it about 44 years ago.
Graphics make it explain better. Thank you for such a useful video!
verry much yess
@Rishikesh upload more electronics videos 📹👀
@@cryptocsguy9282 sure!
Excellent explanation of 555 IC. Nothing was left out and the graphics were superb!
The best explanation of 555 timer i have seen yet....well done !
Well-explained in a concise and understandable manner. Thanks to you I built a much clearer understanding of the 555 timer and how it works. Excited to make more NE555 projects without my usual hiccups in lack of knowledge. Cheers to you, man!
6:48 If anybody who reads this is curious how to derive that t=1.1*C*R result, its simple.
capacitor
--------| |--------
| |
| \
| / resistor
| \
| /
| |
| __ Vcc __|
constant Dc
dq = i dt
i = dq/dt
Using Kirchoff's law,
q/C + R i - Vcc = 0
R (dq/dt) = (Vcc . C - q) /C
dq/ (Vcc - q) = dt/ CR
Apply integration on both sides with limits LHS.. from 0 to q, and RHS..from 0 to t.
then you will get,
- Ln ((Vcc .C - q) / Vcc .C) = t/CR
From this we can easily get this result, i.e
q= Vcc. C (1- e^(-t/CR))
since q=CV,
V = Vcc(1- e^(-t/CR))
Now apply V= 2/3 Vcc in this formula,
you will end up with t= ln(3). C. R
[ln(3) = 1.0986 = 1.1(approx)]
Happy learning!
Absolutely beautiful explanation of a 555, the best I have seen so far. I'm very glad I came across your channel!
I also made a flip-flop with NPN transistors in a NAND configuration, that was fun :)
Thank you!
The explanation and graphics are excellent! Thank you for taking the time to create this tutorial on the 555
The best tutorial on the 555 timer on all of CZcams!
Though, as a rookie, I didn't fully understand the video, I give the video a perfect 10. I have to come back to your site again and again, as my knowledge picks up. Subscribed already. Thanks.
I don't think there is a better explanation than this.Thank you very much for your effort.🤟
I've used them for years and never really took a look that far into the internals. Nice work.
Best explanation on the 555 timer to date.
Thank you so much. This channel is one of the Internet’s gem.
Thank you!
Excellent explanation of the 555. I usually prefer still images/text over video, but in this case the video and the animations were fantastic and really make clear how the device works. Also loved seeing the block diagram of the actual schematic with the different parts highlighted.
Glad it was helpful! :)
Best explanation of a 555 I've seen.. Thanks!!
I am going to review this video several times. I would also like to see him do the LM386 Chip.
this is the best video in the world that i have seen explaining how the 555 works. thank you very much for this easy and very very clear explanation.
Thank you for this simple explanation
I've admired and used the 555 (556, and 558) for decades. Your video was very well made. Thank you.
Thanks!
This is without a doubt the best explanation i found of a 555 timer. Thanks!
Thanks!
I have to sya, this explanation of how the 555 timer works is beautifully done. It's simple and clearly illustrates what's happening internally. I definitely learned a lot more with this than I did in previous 555 timer videos by other EE youtubers.
That was indeed interesting and well explained. Thank you!
The best explaination that I have seen. Read the book on the 555 timer and this just makes it all make sense now. Thank you.
Glad you found it useful. Cheers!
Best 555 video I have seen here, bar none.

Great videos by Dejan Nedelkovski. Very proffesional. Clear English and every word to the point not too much bla bla like by others.
Great video. I remember this from school in the 90's.
The BEST VDO ABOUT 555 INTEGRATED!!!!
El mejor vdo sobre el 555 de toda la red!!!
Quinientas Cincuenta y Cinco Gracias!!!
Thanks to you, i think I'm beginning to grasp this
The best explanation i have found so far!
I just want to tell you " thank you so much!!"
Just made a 555 timer on a bread board and this video really helps me connect both ideas together and now I fully understand, awesome presentation (edit: by making it I meant making the inside of a 555 on a bread board)
That's cool, I'm glad you found this video helpful! :)
The best explanation how 555 works..well done and thanks
Excellently explained!!! The best! Great dynamic diagrams too. Thank you much.
Stvarno dobro objasnjeno! Explained really well!!
so easier to understand 😍
Most efficient tutorial of this topic!
My first solid state project in electronics class was with the 555. I was a junior in high school, it was 1976.
Oh wow, almost half a century ago!
thank you for this video best explanation of the working of 555 I have seen till now
it took ages for my professor to explain the NE555 while this guy explained it even clearer in just 10mins 😆😆
Suparb ,
Like the way of explanation.
Really appreciated.
Very interesting.... as usual on your site! 👍👍👍👍
Superb explanation - thank you so very much!
Finally a video that explains it!
Beautiful explanation thank you very much
thank you so much. i need this type of video
This is the best electronics video I have ever seen. Man, I wish i could tip you!
Thank you!
The Most versatile IC ever Devised...
Great explanation and presentation is beautiful....
Thanks a lot....🙏
Such a good explanation. Thank you!
Thank you for your knowledge, very useful
Well explained. Thank you
An excellent explanation of the 555 timer !
Always wondered about this, thanks.
Well detailed and clear explanation....
This is the best explanation ever.
Please do a video series on electronics basics.
This is the best explanation about 555 timer ever, but I need one more thing, the demonstration for this two formulas (TH and TL). I need a video to understand how to get these two from capacitor charge and discharge equations.
Thank you for help me fully understand!!!Your explanation is very clear!
Wow..you make this sound super exciting, even though I hated this subject at my uni :D
😂
Well done video! Thank you. (Hang blankets to absorb room echo.)
Wonderful! You have gained a new sub, please keep up uploading this quality content, you will success. Thanks a lot, greetings from Argentina.
Thanks!
Federico Coronati - why are you here? Don’t you talk “Mexican”?
Very good explanation. In detail and easy to understand.
Thanks!
wait but its not walking
Wait some more...it will😅
I got that reference 😆👌
Very well explained video (Y) +1 subscriber
That's for the formulas. to time. great work.
i have already designed my own 555 timer IC using bjt transistors, i derived all the equations even the FM modulation equation.
Awsome video sir
thanks for this video...love you man!!!!
Excellent video. Wish I had these when I took my basic electronics courses!

You are actually Awesome! You are an inspiration to me. All the best and reach heights! Love from a lil Indian CZcamsr.
Best explanation from a functional level. You should do one from the perspective of the component level now instead of the functional level. I can't find any that walk through the individual transistors, diodes and resistors that make up the circuitry.
Very well explained video, I am an electronics noob but I think I understand the modes to an adequate extent now.
One thing though - it might be capacitor fundamentals but in *astable* mode how comes the input voltage (to the entire circuit) doesn't stop the capacitor from discharging?
Thanks. The capacitor is discharging because in that case the discharging capacitor is active, meaning the the VCC is connected to Ground via the R1 resistor, or if there wasn't a capacitor the voltage at R2, C2 or the threshold and trigger pins would have been zero.However, the voltage is not zero because the capacitor was charged and now is discharging from those 2/3Vcc until 1/3VCC.
Scott Anderson led complants
Addition to How To Mechatronics, Current is easily flow to the discharge because there's no resistance (very minimal resistance) at the discharge transistor vs R2 that have some value of resistor. So VCC get attract to discharge transistor easily ._.v
ល្អ
This helped me on college presentation, thanks a lot!
i love your videos :D
Ahora si entiendo como funciona el 555.
Si sabes de flipflops.
De comparadores.
De resistores pull up y pull down.
De buffers.
De divisores de tension.
De circuitos RC.
De transistores NPN.
Si sabes de lo anterior???
Sabrás como funciona el 555.
Thanks a lot for this super video.
Desde guatemala saludos.
