i thougth i knew 555s, now im looking at the ceiling thinking wtf am i doing with my life
Glad I’m not the only one

This is the best explanation of 555 timer IC I found
You aren't the only one mate.
you have very neat handwriting Scott
He does
Yeah, and English isn’t even his first language
Im affraid that for half fo us this is way too hard to catch on, all too quick D:
Did that, as pathetic as it may sound to someone who actualy understands electronics, but there are to many elements unkown to me. I'd need to sotp the vid, go investigate what is that flipflop for instance, then come back and lsiten to the rest of it.. Ijm just too dumb.
iceberg789 that's right xD 14 hours of study compressed in only one video. for me at least xD great scot is indeed great xD have a nice day!
I agree with both of you. that is the beauty of youtube and having so many people talk about the same thing. you can jump in the deep end and not understand lots of things and you can go and listen to a noob which both are very usefull, when your goal is just to learn. just use your intelligence.
its like if you speak to the top brain surgeon you probably wont understand hardy anything but talk to the beginner he will probably spend 10 mins talking about keeping tools clean. where the pro never mentioned it once but its fundamental. But use ur intelligence and you can learn key points very fast.
it would be unfair to ask the top brain surgeon to cover everything from the most basic and you would miss out on the cool stuff he really knows.
For me it makes sense but I'm already in school for electronics. I think this is who it's primarily for.
Am I the only 1 watching and not understanding almost anything, but still likes the video anyway?
*****
Well, that's unfortunate... nobody else but me likes Scott's video...
You're not alone sir...
Not at all
watch codenmore's video, its amazing
He did hurry it up a bit...
The 555 has been my favorite classic IC for over 20 years. I really enjoyed this video and learned some new things about this awesome, long lived chip.
pls suggest if there is really any way to generate good square wave using NE555/NA555 IC? as I only have that available with me
@@kritikagupta8585he showed you how to do it in the video with the astable cmos 555 timer 😭
Finally, an actual video explaining what is the 555 like inside, thanks a lot
Best 555 video on UA-cam! Thanks GreatScott.
I wish you would have posted this video a day earlier. I had a 555 question in my exam 😑😅
iceberg789 lol. I hope not. Results aren't announced yet. 😅
how to make HAND GRENADE at home............WATCH ON MY CHANNEL
Better hope the grenade fuse is made with a 555 timer with a 10 second delay
subcribe to muh channil and i'll post a video about how to build an anti-matter bomb.
tested. it works i'm commenting from hell right now. ...connnection here is shitty though iceberg789
The 555 was my favorite chip to use in high school back in the 80s. Boy I feel old.
i was just telling someone i am about 3 decades late with this hobby of making circuits with a 555
This has to be one of the best electronics videos I've ever seen. My sincere thanks to you
I LOVE THIS! it's going in my recipe book of very useful electronics chunks. EVERYBODY got time for a pwm generator!!
what ??? You have made me completely understand a timmer IC unit in integrated circuits subject ....thank you so much...
I've been using 555 with no idea why we connected it in such configurations .. when u got to the deeper level .. everything is clearer .. thanks boss
I believe that this is explained well and simply, but me small brain could not grasp most. I have bookmarked this video and will be back later when I understand more. Thanks Scott for the inspiring video :)
The topic is very old, but the explanations as usual are great. I especially love your hand-made diagrams that tell us how we should think about electronics, how it works in detail. Great job Congratulations
Why old???
Your Courses are really useful! love from algeria
Great Scott, that's the most absolutely fantastic explanation of my favourite IC, its so crystal clear now, thank you
It's my first comment on any youtube video and I just love watching you video I just started watching your video from last few week in starting I use to watch any random video of your then it just blood up my mind because I am not from technical background but I like it so I watched all your 26 electronic basic video and it helped me a bit knowing what you are doing and after seeing your video I too want to make things for my self and I will start from making a bench top power supply from atx and thanks for inspiring me
if this is the basics I'm fucked cuz I only understood like 30 %
this is the basics of a 555 timer, it just requires you to know other basics like flip-flops, bpj transistors, comparators and voltage dividers. Find tutorials on those and you should be able to understand this (although I still have some trouble with flip-flops, they weren't discussed for very long in my classes)
It is much easier to understand your videos with a reference book at my side
Great vid,This is the first explanation video that didn't go to fast for stupid me.
I built all these circuits 25 years ago! 555 stands the test of time. I wonder how many have actually been made
Hey When Are You Doing DIY Wireless Energy Really Want To See That BTW Awesome Video As Always
Probably next week
+GreatScott! Thank You Very Much Keep Making Awesome Videos
why do you capitalize every first letter of a word?
@@magerehenk7579 still thinking about this
Your videos are amazing ! So much information, you're going straight to the point without any detours. The information is tightly packed and the whole subject is covered quickly and efficiently. If looking for one specific information, I can watch 4 or 5 videos in what feels like no time and I'm very likely to find what I'm looking for. As an other non native english speaker (i'm french) I am very happy to be able to use english as a way to communicate with somebody that eager to make the world a smarter place.
Hi sir i want to know why we use clock pulse in sequential circuits and what will happen if we dont use one? - ur simple ways of explaining amazes me your big fan....
Always good quality and frequent videos
Do you keep the hard copies (printed circuit diagrams that you use in videos, calculations that you do, etc) organised in a file of every project that you have done?
Best 555 timer explenation video that i ever seen. Thanks from Poland for your work.
I see this all the time on UA-cam that people say that the 555 is the most used chip of all, the strange thing about that is I never came across such a chip in any of the hardware that I took apart for recycling, I recently bought a few just to get familiar with the chip.
Today I've got the blinking LED working for the first time, pretty neat but it can be done much easier with less components so I don't really see the advantage of it.
Thank you Scott, your videos are short and super clear. Keep making more. 🤝
You're one of the most interesting youtubers ever!
Thanks
Question for your Q&A: how do you choose which intro video/music to use? I always try to guess, and I'm not always right :D. Also, keep up the great work, I love it!
I like the old school drafting!
That intro exploring the internals of the 555 was amazing! Great work !
As Per usual, Scott. Quality video and good explanation. Keep it up, sir. You've more than earned every sub.
true
just in time. I have it included in my upcoming exam . Thanks alot.
Thank you so much for this video, really very useful & enrich my info about 555 , wish you good luck
شكرا جزيلا على المعلومات القيمة
One of the best videos
Great Scott, great videos.
Every times he said flip flop, i giggled
The video was really good! Easy to follow when you take time to draw everything, which forces you to have a slower tempo! :D
darnit... so easy yet so complex.. thank you for this video and keep 'em comming :D
Another great video, Great Scott! My advice is to keep up your high tempo, despite the complaints that you're going too fast. I'm a beginner, and you're "too quick" for me too, but that's good motivation to learn more so I can eventually keep up... and your videos are never boring! In all the language classes I've taken there is always a student who complains the teacher is speaking too quickly. One teacher responded "No. You're listening too slowly." That's right on the money!
Nice fundamentals lesson, Scott! :D
Thanks
GreatScott!
wtf?^^^^
How is it important for this video?
+GreatScott! Pls Make a video on inverter ( may be 5 level )
Whoaa!! Great Scott! Lessons that I learned.. 1million subscriber, keep it comin'! ☺ 👍
Awesome video! This is THE channel I was looking for all this time, thanks :D
Great Scott! Another fantastic video :) I was not aware of the CMOS 555. tnx.
You are awesome 😀😀😀
Hello scott, as u showed here in the explanation dt u used pin 3 as input from the pot and the diode combination, but in yr actual application of fan and led dimmer u used pin '7 as input' and 'pin 3 as out' put which works pretty well, but my question is it possible to use 'pin 7 as output' and 'pin 3 as input' (from pot). Because A guy did that and when i tried using his schematics i failed to get anykind of out put from 'pin 7' and also he used '12v zener and 270 ohm resistor'to use 555 on 24 v supply bt when i tried my resistors heated up like in seconds
Here is his vidio and schematics ua-cam.com/video/trlUiFwl6AE/v-deo.html
And also make a video on using zener diode as voltage regulator if possible
thanks in advance
Nice vid. As always.
Awesome! I’m into hacking old instax cameras and this should help controlling the eject mechanism!!
very nice way of describing thanks.
Greate video from tunisia
Another great video sir!
Man, I have a question for you. Don't know anybody else better to ask. I just bought something that is... Kind of a "dc motor". But it looks like a stepper (because of the wires exit of it) and doesn't run on DC. But it has only two wires! More: I just tested and it looks like a stepper coil! I tested its continuity and the multimiter beeped! O.o What the hell is that? LOL
Great video (as always) - thanks for sharing these!
Thank you very much very succinctly explained
I was thinking of using a 555 to add PWM in conjunction with shift register output and I guess I could, but I'd need one for each output for individual control. I'm afraid I simply don't know enough, haha.
For once, I actually fully understand a GreatScott! video :D
Edit: Not to say your videos are confusing, but you explained the 555 in such a fantastic way.
It was well explained, but it still went over my head. I have a lot to learn!
kudos to your intro bro!
Had to watch this to realise the output from the flip flop is low when the main output at pin 3 is high. The book I was reading did not make this clear so I was getting confused as to why the discharge transistor was open when when the main output was high! I take it the output stage goes through an inverter?
thank you so much scott for these lessons ;)
+GreatScott You're superb awesome!! I watched your electronics basics series and helped me in school! Thanks for that and I really do love electronics... :D
Excellent video !!! Nobody does it as well as you !!! Thanks !! ;) ;)
Donald Filbert
it was superb, every week we have a nice surprise here!! Thanks again.
You're welcome
Something is wrong with the diagram at 7:01. You are sure that the output should be partially (through the potentiometer) send as a feed-back to the 555 through pin 2 (and pin 6) ?
GreatScotts, I am also an electronics student. Watching this fundamental concept on 555 IC is so refreshing. :) I really enjoyed it.
Btw, which digital oscilloscope you are using?
very nice video..thanks for information
Where did you learn about electronics? Like was it from college, or UA-cam videos, etc.
Work and university.
I'm using 555 for decade counter triggering as in normal switch it gives a run on counter but still there is key rebounce issue.
Nice demo as always,
Could you please make a video for make external watchdog for arduino using 555 if.
On diagram with double switch, pin 5 does not need capacitor
I have a question about the last example of PWM signal. Considering the lower current capabilities of the TLC555 and the fact that we use a part of the current to charge the RC circuit, I guess it's only suitable to drive a high impedance circuit at its output, right?
I tried assembling this circuit, sadly, as I am just starting out, I have limited amounts of components. When I use a 10K potentiometer (don't have any other atm.), a 104nF and a red LED at the output
- with small resistor at the LED, nothing happens, which is probably because of the high difference in resistance between output path and charging path.
- with a big resistor at the LED, adjusting the pot. changes brightness a little bit, but the LED's brightness is nothing to brag about to begin with.
- when I disconect the LED and measure the voltage out -> gnd I can get about 0,5V - 4V depending in the position of the pot.
Could this be because of little output current of the TLC555? I guess I really need an oscilloscope if I want to get any further into electronics.
Great video
Nice Video thanks.
Hi, I'm a noob in electronics (I usually work with Arduino), but I wanted to start messing with chips, transistors, and much more, but I don't know how to read these weird schematics (I know how to read the circuit schematics, but I have no idea about how to read the diagrams I usually see to explain chips). Can anyone help me?
Ha... So... I understand...I guess..
So what is a 555 timer again?
It usually took me 10-20 replay with me trying it myself to get me understand it.. The quality is good tho..
Cool but I have a question if you had a broken or old printer how would you repurpose it ?
I'm a complete beginner, but I thought the capacitor connected to ground at 2:38 would immediately discharge to ground? What am I missing?
Its charged the opposite way mate
So its negative is in ground side and positive the other
The capacitor will discharge through the resistor
@@abhijithanilkumar4959 Thank you friend.
@@abhijithanilkumar4959 Would it work with a non polarized capacitor?
Amigo que gran video ¿no has pensado en hacer versiones en lengua hispana para aumentar tus vistas y así tambien ampliar los países a los que llegas con estos sensacionales videos?
Hi Greatscott i live in Germany Chemnitz can you please make a draw my life video
I find that just using an Arduino board (or any micro-controller with PWM) is easier because 1; you don't need any extra components other than a potentiometer and the load and 2; I find writing a few lines of code easier than hooking up components in a way that I only somewhat (even after watching this great video and others) understand.
There are applications when using an MC is a waste. Sometimes it just comes in handy to know how to create some simple circuits without programming anything.
this was too good :) .. thanks
New intro? Cool! How did you build it? Make a video of it Please.!
This is the intro for his "Electronic Basics" series - not that new!
am i the only one that said
"The Fuck?" at the end of the video? cuz i only understood half of it
Well done
thanks man i retained none of that but i liked the vid
hey Scott , can we use the back emf generated by a motor to control it's rotation instead of using a hall sensor in the motor controller.
why are ne555 used instead of tlc555 then?
Tradition, price, technology, availability.
Since the these chips are not 100% compatible with each other switching from one to another on existing design is potential risk. it's easier and safer to use old chip with existing designs than go trough entire system.
There are many differences to check like input&output levels, current delivery, operation speed&voltage range, power usage, temperature range, rf interference, decoupling needs, esd sensitivity, ... Most of them aren't likely to become an issue, but one can't be sure without testing the system.
On new designs, it'll be balance of availablility/price and features. With the jellybean chip like 555, the price won't be an issue and availability should be fine for most common types.
So NE555 is talking with IRFZ44 now? Okay.. I might want to shake my head a little now..

Make sense.
More current, he explained it.
you are such a Junius .I like your every videos, your learning process is too clear to me . Now a days I am studing on sstc and I want to make such a high power solid state tesla coil but I can not find the ucc37321 and ucc37322 ics .Do you please help me to drive the gate driver transformer with out this ics ! I cant drive the GDT to start the igbt, have you any solutions?
my favorite youtuber looking at my favorite IC, its a happy day
Would arduino make a rocket go to the moon? I think it will.
nice video
make a 2 or 1 channel transmitter & reciever.
Hallo Scott, und vielen Dank für diese Lektion. Es war gut für mich, weil ich neu in der Elektronik bin. Ich frage mich, ob Sie eine Serie mit Soundoszillatoren und vielleicht Sequenzern und Zählern machen würden.
VOOLTAGE and COMPWARITAR... That explains why i cant do this myself....
Can I use the 555 timer I.C. in astable mode to control a servo? If yes, what should be the capacitence of the capacitor added?
SSSSSSTAY GREADIFF!
Yes, Sir!
Nice video
Nice video
What a coincidence i was messing arround with one NE555 just now.
And this video helped me to solve a question, its like im asked a question and GreatScott! Created a video to reply.
Thank you a lot for the video and keep up with the good work.
