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)❤️

[@Dakseru]

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!

[@NicStage]

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!

The best explanation of 555 timer...

[@michgingras]

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

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

[@maffysdad]

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!

[@hoofheartedicemelted296]

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.

[@claytonbenignus4688]

I am going to review this video several times. I would also like to see him do the LM386 Chip.

[@kevinbyrne4538]

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.

[@ShelliLoop]

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.

[@ravplayztabla7467]

@@ShelliLoop wow you're stupid af.

[@SqualidsargeStudios]

S H i agree, the English is shoddy and needs work.

[@jovetj]

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.

[@themightyimp08]

@@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.

HOLY CRAP. The 555 timer is still around ! Amazing. I was using it about 44 years ago.

[@MaxImagination]

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!

[@tatvamkrishnam6691]

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!

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.

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.

[@Driftload]

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?

[@HowToMechatronics]

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.

[@manojkm9219]

Scott Anderson led complants

[@RichardHowin]

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
