#UART
#i2c
#SPI - วิทยาศาสตร์และเทคโนโลยี
That was a nice explanation! However, I want to mention few things
1. I2C is Half-Duplex (not Simplex)
2. SPI is Full Duplex
3. In I2C, we can configure the peripheral to both the modes - Acknowledge and No Acknowledge
SMBus and I2C are slightly different protocols using the same hardware. Isn't No Acknowledge actually SMBus?
what is I2C Protocol in Arduino Nano ?
@@elhoward7440 no, ACK and NAK are both part of the I2C addressing protocol. When you write to a slave, the slave needs to pull down the SDA line to ACKnowledge that it is ready to receive communications.
@@AMG-gc4io Its the Wire.h library and the same pinout as the uno (A4,A5)
Also, I don't think you say Bauds/second, as 1 Baud = 1 bit/second
This is something I was really planning to study and the fact that you made a video on this at the perfect time is just awesomeee thanks😄
This is honestly one of the most helpful videos I've ever watched. I wish I saw this in school a few years ago.
fuck schools man schools never teach you shit. of the 100% of content I learnt from college(in which my major MATSE is top 10 in US) probably 15% of the shit is actually useful. rest they just make you jump through hoops and run in circles and chase your own tail. I talked to professors and very smart people(well, smarter than me for sure) and they all tell me they purposefully make this shit difficult. I picked up more programming stuff in a month with my flipper zero than an entire semester worth of programming courses in college/. by the end I finished my college programming class i still have trouble fucking printing hello world but with interest and a bit of self learning I'm writing sql now.
I m not of this theme. Even dont know what that chips are for.... i m cab driver . Wanted just watch some fun on utube before sleep.
And even I understood how these guys communicate😊
Really good lesson.
I wish i could see that 50 years ago. Maybe that could change my life
CAN and JTAG would be interesting.
+1
JTAG, CAN, RS-232 & MIDI
CAN is also very commonly used in protocols. Please make a video.
Yes I would love to see a deep dive in to can
Absolutely agree. CAN bus would be great.
Finally I understand how timing of serial communication works. Thank you.
I so appreciate you elaborating these concepts on the circuit boards. That literally saved me hours of hustle. Very well explained! Thank you
Thanks for simplifying these seemingly complex protocols for us. Up until now I kinda treated them as black boxes in my head to keep the complexity away but now it feels great to have a fundamental understanding of how they work. Although Id love to see a bit more explanation on SPI.
You just have made me understand one of my most confusing Topic. so glad to have you in my subscription list. You are amazing. realmente te aprecio hermano
Thank you. As I am learning how to make things for myself, these come up a lot and have been wondering exactly why a certain protocol might be more useful in certain situations. This helped me a lot to continue my learning. Thank you
Very well done. One of the best explanations of async & sync serial communication I've seen on TH-cam. Would love to see you cover CAN, and JTAG!
You make it much easier to understand using your Scope. It is nice to see someone knows what a Oscope to display what you are describing. Keep up the good work. UP SCOPE !
The best explanation I have ever heard!!! Hats off ;) This video just solved a great mystery in my mind on serial communication.
I respect and really appreciate the effort it would have taken for you to make such nice animations for explaining. Its a delight to see your work . I'm a fan, really helped me to understand concepts better. I will appreciate if you show more of oscilloscope result with a simple example data. Otherwise i love the work. Its just A1 class
Since long time, I was searching for such an explanation and today by your video my concept got clear about bauds transmission. I'm really thankful to you for that.
This is a really great video. I teach this in my intro to engineering class and this video is going to be a must watch addition to that lecture. Cheers.
Really concise summary. I had next to no idea of each of these implementations, or even much of an idea of their spec beyond a communication vector, so this becomes a very welcoming introduction and comparison
The most simplified video in the field of telecommunication ever, thanks a lot
This was a concise and well-defined explanation. It is the first time that I see such a great video in this subject here on youtube. I'm inclined to be your subscriber now, thank you.
Wow, it's really rare to find videos that are explained so clearly !
In every video your animations are a pleasure for the eyes!
Thanks for making this video! You clearly explain how these forms of communication works for beginners (or me at least). A lot of things regarding computer and signal communication makes complete sense now. Keep up the great work!
This presentation was one of the best I've seen in a while. Simple and very easy to understand. thanks🙂
Amazing video. I was always wondering about different types of communication! Thank you!
This was so helpful. I wish my digital electronics professor explained it like this. Thank You!
Please do more on CAN communication and the others. You are such a great help in education and simplifying such difficult subjects many thanks
You removed all the doubts which I had since 30 years in my mind
Thanks alot
In one great video I learned so much about the serial connection I use every day on my arduino. Thank you
Awesome Video tutorial on Serial Communication with very clear explanation.
Kudos Electronoobs!!!
Thank you for this video.
Best thing about you, is that you keep it very simple yet effective.
Please make a video on CAN communication.
Thank You Sir. My concept cleared about UART, I2C and SPI communication through this video
Thank you bro, you have explained the concept confused me for a longtime in a way that even a beginner can understand
this is the only video on the youtube which is very clean about protocols
This is the first video that explains this in a way that makes perfect sense to me. Thanks!
Oh my God !!! i am so thankful to you. I mean u did so much effort on one video for explaining each and everything and that too for free❤️❤️❤️❤️❤️❤️u r legend
Thank you sir I have been using these protocols for quite a few years now. This video explained it to me better then I've ever understood. I would just hook it up as it said and not realize the difference.
Please hook us up with the JTAG and CAN most definitely. USB and debug would be helpful as well. I’ve had a lot of trouble finding good videos for these, but this one on serial communications was superb!! Well done!
Thanks for this video! Best explanation for a hardware guy like me I’ve seen. Getting into UART for BLE radios here.
Thanks sir I am lucky that I have found this video. This is the best explanation about digital protocols that I have ever seen.
Thanks a lot for this.
We need a video on CAN protocols too, thank you so much for this video.
best video so far explaining protocols in a simple way! thanks for doing it!
Dude I couldn’t explain this any better. Well done
@electronoobs, just a little correction needed in the table at 10:27. I2C does have an acknowledge system. The slave will pull the SDA line low when it has successfully received the transmission from the master. This will show up as the last pulse that appears after all the data bits are transmitted. This last pulse will be a high if the master does not receive an acknowledge from the slave. This way, you can clearly get a confirmation of the handshake.
Why not you should surely post more.I really admire and thank you for these videos.Keep it up.
So far the Best Video i have seen on Communication Protocols! Amazing explanation bro!
Best Visual explanation of protocols ✨✨✨
Really appreciate your work.
This is a really awesome video! I've rewatched it 3 or 4 times over the years to prepare for interviews
They actually asked you stuff about this?
Very very nice explaination with practical! We need such brilliant teacher for the world!
Eres un grande amigo! gracias por renovar mi amor por la eléctronica. Sigue asi... tu eres digno que te llamen Maestro.
Very nice and well explained
Now I know how different types communication works thanks
Great, this video is more helpful for everyone. your way to teach is totally awesome.
I wish I would have paid more attention in school. But I'm glad ppl like you are around to whip me into shape.
Very clear explanation. If I may suggest--It may be worthwhile to draw the vertical sides of the pulses slightly slanted to remind us that the pulses are not ever square, but it takes time to climb from low to high and likewise to fall from high to low. I believe that the counting actually takes place at the middle of the slope (zero crossing) of the leading and trailing edges.
Thanks for taking the time to produce this video.
The best explanation I have come across thus far...thanks!
Well done, nice explanation. It's worth noticing that I2C is bi directional too. A master can read values from its slave devices.
This is great, hope this series continues
With each new video, quality of content is increasing. This channel is next eevblog.
Man! Very clean and simple explanation. Thanks. Please explore other protocols also in more videos.
great job man!! very shortly and precisely you describe everything.....
So revealing, I've always been curious about serial communication
Very simplified explanation of such complex concept.
This was excellent, exactly what I was looking for. Nice overview.
Great.
Please make video on protocols like CAN and USB.
Yes sir we want more videos on this topic thank you, you are awesome
Love from india

Thank you so much. This video is really helping. I love your channel. Keep the good working.
man your topics are just what i need ...just thanks man
Wow, this is such a great video, thank you for making it!
I have worked a lot with MIDI protocol, it uses mostly three 8 bit bytes in a row with a low going start bit.. started in the 80s for communication between synthesis and still used today even professionally.
Yes, more protocols. Thanks!
Very nice informative. Short and sweet. No wharra wharra. Just straight talk, how technical people like it 😋👍🏻 Thanks
Please make for other serial communication protocols. I am waiting along with other thousands of people. Your explanation is excellent.
Easy understand videos. Its Better than the IOT class lectures that i attended in my college.
Really nice illustrations, loved the voice over too. Perfect video 📸 🤩
This is awesome amazing superior mesmerizing unbelievable overwhelmingly beautiful and breathtaking
This is super important, and when you make a video about it, it becomes demystified, understandable by humans 😁 thanks a ton a ton, keep it up, love your work.
I am sure most of your audience agree with me
Great video! Short and straight to the point! Thanks!
The explanation is very good..pls continue making more videos
Amazing video. Congratulations for dedication and quality.
Hello!
I am pleased to see this video, you really made things look so simple, keep it up my friend, cheers...
just superb learnt a lot today. very important for a drone guy
thank you for the clear concise explanation.
Its really a clear explanation with all the variations among communication protocols. Expecting vedios on CAN and JTAG. thanks for the vedio..
Thank's I was searching this explanation to build my 3d printer, now i kinda know what portocol to use with my step driver, i chose SPI, gain of speed
I enjoyed a lot this video,showing the oscilloscope waveforms. Awesome. Congratulations.
we have a youtube channel that deals with Arduino,ATmega328P,Java,Serial programming ,robotics. So if you like these stuff do Subscribe. Sorry for annoying
Masterclass, I studied a bit of this decades ago but much better explained. Now I want to create an MBUS CDC emulator for 30 years old car stereos.
Great video buddy cant be more simplified than this
Nice video man You inpired me to start youtube and making
videous I love how much work you put on videos You are awesome! I love some day to be one of my subscribers.
I agree! Well done videos! Mine are unedited and nothing even close to these!
You explained serial communication better than anyone else
WOW! Really informative and compact. Thank you!!!
O sotaque não engana. TUGAS NO PODER!
Thanks, this is really the best explanation online.
This is really helpful overview. Thank you :)
thanks so much for the video, is so helpful for my exam ❤
