There are only a few people who can teach topcis with such clarity. Thank you sir!

You truly have a gift for explaining topics with clarity.

The best in-depth tutorial about Digital and Analogue Signals.

Coming from a guy who watches 100s of tutorial videos on the web and never comments on any of them, this is a really great tutorial. Thanks a lot for making these.

Thanks Jeremy! Your videos are all great (without exception). I'm a structural engineer, and I'd chosen structural because electronics and programming intimidating me until recently. I've been finding resources like yours to be very informative. It all makes sense now (for the most part) :D

Listen, You're the man. Keep it up, and open source. People like you make a change

I love your book and presentation of the material, I'm a mechanical engineering student learning the basics of using an Arduino for a senior project, and your videos have definitely helped me sort through some of the confusion a beginner faces.

Great Job Jeremy - You will be a leader in the next generation of electronics - there is no doubt about that.

I know it's been 10 years now but this info is still such a help for me, you are a great teacher man. Very easy to follow and understand!

Awesome video, I'm in high school and I go to votech for automotive, everyone is always telling me how many computers and electronic concepts are involved in the field and in this video I was really able to connect a lot of what you said to what I am learning.

I thank you for the Arduino videos as well as videos that explain these principles. I'm about to be a sophomore at University at Buffalo in the field of Electrical Engineering, and they use a lot of Arduino in the upper classes from what I heard (which at this point I'm not surprised anymore because of how helpful it is). You have helped me gain an upper edge on my classmates and I just wish you well where ever you skill and knowledge will take you.

Great job. Started a few days ago with a microcontroller. Been a welder for 30 years and learning electronics from scratch. Thanks.

thx you helped me get en A+ on my test at school and you and your brother have to make more vids, they are so helpful

Thanks for putting the time to sum up in detail what the differences are. I hope your hard work is paying off!

Core concepts nicely articulated, well done, most impressed on the delivery.

One of the best online tutorials I've ever seen. Thanks.

@byxxi I'm glad you liked the video. I sometimes forget that I'm talking to a worldwide audience! I'll try to be more mindful of things like that in the future.

Thanks for the video. I'm going through your Arduino tutorials and came here because it was recommended in lesson 2. Great explanation of PWM.

Great job man! You managed to cover same amount of information in 17 minutes as my professor in two, 1.25 hour lectures.

Thanks for that comment, because I was just about the write the same thing. Hope people watching the video read these comments, because that is not at all the way the 10-bits relate to the analog value. It simply means that whenever a sample is taken (and compared to a reference voltage), it can be represented with 10 bits (1024 values) of precision. So koktelici's 4.8mV "precision" simply means this: 5 v / 1024 values = 0.00488 volts / value That's about 4.9 milliVolts of precision per sample

Thanks, Jeremy. Very helpful. One small suggestion: try to find a camera angle where your hand does not block our line of sight to what you are writing. But the content itself is great. Thank you!

You explain things very well. Thank you for helping me learn. It's an incredible gift you have. Unfortunately most of my professors do not have your ability.

jeremy you're an excellent teacher!!!

I learned more useful information watching this video then a week of school.

i just subscribed. thank you for explaining this. everyone's right, you have a gift for being able to articulate topics you're trying to teach; not many people can do that. Keep it up!

@KillaMarci I was trying to not go too in depth. They are generally called logical operators. That may be a topic for a future episode focusing on digital logic control.

Pulse width modulation with Light Bulbs. that was fascinating-- had no idea dimmed lights were actually flickering high speed at on off rates!

All I want to say is THNK YOU,you really helped me to understand it clearly

Great video! You started simple and got to the really detailed points of interest. I look forward to seeing your other videos.

Im watching this video in 2024. I can only imagine what Jeremy Blum is up to now.

dude your awesome you just thought something I tried to "know " about more than 7-10 years

Finally a clear and very very well explained video! Really good! :)

Great video man, Jesus though I wish I watched this sooner for writing about digital and analogue signals for a past assignment, its certainly solidified by knowledge further! I'm watching your Arduino tutorials too, definitely subscribing!

seriously.. you are the best explainer...

well explained!!! but that marker noise scratching against the paper is very annoying :|

The bs2 can also do PWM. It has a command called PULSOUT which is mainly used to control servos and IR LEDs

What a superb and very informative video Jeremy. I am learning.... albeit very slowly!!

Thanks for the great tutorial Jeremy. There's one thing I don't understand in your video. When there are 10 bits in the analog to digital convertor, the resolution is 1024. Why are there only 10 steps in the sine wave analog-to-digital conversion? Shouldn't there be 1024 steps instead?

Thanks for evething you do helping newbies. I was lost and still not found but I am starting to figure out the map with your help.

Extremely helpful. Thanks a lot. Brilliant presentation.

thank you very much for taking the time to make this vid. very helpful.

Your tutorials are really helpful...much appreciated.

Explanation is appreciative

@jeriellsworth It's all about the table of contents! Too bad you have to wait for the video to buffer enough to actually have the links work properly.

Hey man, your videos are awesome! I just subscribed to your channel. I'm anger to watch all your video and learn something more about electronics.

Well i learned way more then i set out to. great vid n teaching methods.

learning @ internet speed. Thanks brother your awesome.

Really love the way you explain this, because some of this is all new to me, and I think I get some of it, but you should think more about your audience when you say that people have 60Hz in their power outlet at home, because thats only if you come from the US, almost any other country have 50Hz in their outlet. Just something I wanted to say because Im from Norway. Normally you dont hear that much about Hertz, so I though you might mention something considering the audience. long message D:

awesome stuff, would be good to see some more stuff like this on here..

I'm new to this so all your videos really help. Thanks so much!

Hopefully after you make your fortune you'll pick up a tenure. Coming from my Economics and History background you're quite in the makings of a great professor. Still missing some key ideas (I probably missed in earlier videos), but in due time you'll be able to break down those ideas to the common layman.

Good job your tutorials are very informative

Great video. Thanks so much!!

Thanks for the great explanation of PWM. One thing, though, is that you didn't cover the 'W' part. (I was able to infer it, but had to look it up on wikipedia to be sure.) Essentially, if I understand it correctly, the longer the pulse stays high (that is, the greater the width of the pulse), the closer to 5V the device runs (and vice versa for shorter pulses, causing the average voltage to drop). Then, I guess you can even vary the pulse widths, thereby mimicking a waveform for some purposes?

12:30 you said you weren't good at drawing but that's a great The Alamo

Thanks for this wonderful tutorial, Jeremy

awesome! thanks dude. way to break down all this stuff into understandable ideas!

Great vid and very clear explanations. Thanks a lot.

Awesome video. Very easy to understand

Hey Jeremy, thanks for getting me started with the Arduino. Regarding this video: Wouldn't the 10 bits actually allow you to break the waveform into 1024 different steps, rather than just 10? Only 10 steps could be covered by 4 bits, because 10 in binary is 1010. That's the vertical resolution, and then the horizontal (time) resolution would involve the sampling rate. This comment addresses your video at around 12:20.

Thanks a lot, I watched this and a couple of other of your videos and I found them really helpful.

MAN UR AWSOME!!!! This video motivates me an helped me to step my game up! THANKS ALOT!

Thanks so much for sharing your knowledge, you really do put it across well! brilliantly explained. I wish i would been taught like this when i was younger as I would have learnt a whole lot more.

Jeremy Blum is a god!

@xideathzapix Glad you enjoyed it.

Very good. Thanks for sharing. Roy

Dude you are awesome :D .. learning more than i did from my university ...

really good explanation. nice work!

你好Jeremy Blum！真是太精彩了！

This is impressive, not even one dislike! :)

Excellent tutorial!

as a Chem E coding an ardueno, Thank you for the simple explanation

11:34 You got it wrong mate, 10 bit resolution means that every sample will be represented with 10 bits or 1024 levels of voltage. Meaning your scale of 5 V with your micro controller can be presented with around 4.8mV of precision. What you actually drawn is 10 bit sampling rate of time period.

Jeremy you are a bit confusing. Do you talk about sampling amplitude in 10 bits (1024 levels) or do you talk about sampling 10 levels of Amplitude (4 bits) along 10bits sampling on X axis (time)?

@mrjamesb56 IT's really a matter of what your board supports

This is awesome, man ... :D ... thank you so much for these videos ... I've learned a lot from you ...

Awesome teaching skills...

hey man u cleared all my doubts!! thanks man!!

Thank you for explaining that so simply I finally understand!

Awesome vids man! Keep em coming!

This guy is the best!

@sciguy14 well it was in a sciens class and it was about electronics and electronics signals. and how how we convert them and curent, watts, volts, oms etc. But make more videos like this on.

Impressive, man easy to learn

So many SOLID videos Jeremy! Please keep it up :-)

Yes i would say you have a gift for saying it how it is, thanks!

@GamerKiwi I already have an eVGA classified intel board.

Very well explained. Thank you!

Fantastic video. Thank you

Not exactly, light dimmers most of the time use potentiometers to change the voltage given to the light bulb. Specially those which work only with incandescent bulbs.

YOU.. ARE.. AWESOME.

awesome video man, really great video

Thanks Jeremy!

@jay15183 Haha, sorry about that. I use a whiteboard now. :)

Man you are awessome!! May god Bless you!! When I wl b capable enough, I will surely donate to your blog!! Thanx a lot!!

nicely explained!

I'm new to electronics so could you tell me which series should I watch first techbit or arduino tutorials

This proves you CAN teach an old dog new tricks. I learned from this basic video & I'm 68 years old.

You shouldve probably talked more about the logical converters (is this what its called? not sure, sorry if im wrong) AND, OR, NAND, NOR, EXOR and so on... :P

Really great video. Thanks!

Thank you for sharing!!!
