2 hours of reading and then here comes this video where everything is well explained in under 10 minutes... You tube is spoiling me...
This is one of the only videos I've found that explains how pull up resistors can affect the speed at which data can travel on the SDA line. Fantastic video that explains how I2C works. Great job.
The bit sequence was so well explained that I had to print the screenshot of it for future reference.
Awesome video! I especially appreciated the protocol/packet breakdown. Thanks very much!
Watched many videos on this protocol I was never able to grab the concept clearly and I found your tutorial and it made my life simple . Thanks man u have explained and visualised the concept neatly .
What a great video! Very clear explanation and simple demonstration on how to use it.
Thank you very much.
This is so beginner friendly! Thank you so much. I used the same illustrations to make few students understand the same. :)
This is by far the most thorough and yet still concise explanation I have found! Awesome video!
Thank you!
I always like tutorials that show how to use sensores without relying on 3rd party libraries other than the wire one. Very useful for learning.
Sweet tutorial! Really like the illustrations that went along with your explanation. After looking at a few cool project videos where people are using Arduinos and other microcontrollers, it makes me wish my college had a class on these!
Dejan Nedelkovski
it's been 8 years now or so, are you still alive bud, and did you learn this arduino and microcontrollers stuff. Anyways, hope you are doing good
OMG thank you so much, I've been so lost with i2c until I watched this video!
Very useful for beginner like me, thank you! :)
Thank you for this tutorial! I knew the overview of how i2c works but not the specifics. It looks similar to packets in TCP/IP.
Thank you very much for this video, Dejan! The information is clear, well organized and dynamically illustrated!
You are the best. Thank you for taking the time to explain I2C on such indepth level.
Your examples are very helpful for us slow pokes with little to no insight. Good Job.
Thanks! I didn't want to memorize it, but to understand it and it worked! :)
Dejan,
I was looking through youtube for a decent tutorial about the I2C bus as implemented on the Arduino. I have a class of high school students who could use a good demo. I didnt expect to find your EXCELLENT tutorial, one that would be useful even to professional electronics engineers. I wanted to let you know you did a nice job, and it was appreciated.

This was extremely well done! Good job! It was very clear and now i'm off to do some new projects.
super, really appreciate for the tutorial. Request similar other Serial protocols SPI explanation. CAN, UART. thanks
Hello Dejan
Many thanks for your time to spend in order to explain us these very clear tutorials.

This is fantastic! Sharing on Mondays live show. Great vid. Cheers!
SUPER helpful tutorial! Thank you so much!
I have an ALS31313, and all the code examples I could find online (including the manufacturer's website) don't work.
Your tutorial makes things SO much clearer and I managed to get my magnetometer working within 15 minutes of watching your video!
THANK YOU!!!
Glad to hear it, cheers!
Hi, Mentor. What to say, thank you won't be enough. great, detailed video.
saved me so much time working gy-80
thanks man
Excellent explanation. Also helps me in a project where I will be using breakout boards for the first time.
Thank you
I now understand what I could not understand previously. Thank you.
I watched a few videos and this is the BEST explanation for I2C. Thanks
Glad it was helpful!
Very clear and instructive. Well done. Thank you !
Thank you for a clear explanation. I used only SPI to date but now I know how to use I2C ... thanks...
You explain things very accurately! Thank you!
OMG dude that was perfect. I have been struggeling with i2c for a while now but this made it click. THANKS! :D
Nice, it is desirable in the following tutorials to explain the I2S protocol and what is exactly the difference with I2C
Great description of I2C. Thanks:)
Dejan Nedelkovski, you are the best. Thank you very much for making this video.
thank you Dejan.
great tutorials, very well done the clip too
Amazing video. SOO many hours of reading pdfs with unnecessary tech jargon. You explained it perfectly.
excellent.
thanks a lot.
you helped me in my interview preparation.
дејан секоја чест! браво за споделеното знаење! сеа дознав за твојот канал, ќе разгледам што си споделил со задоволство.
Finally someone who knows what he's talking about ! Thank you! Not one person on the Arduino site or any other place online have suggested hooking up scl to scl and sda to sda . Everyone says hook it up to A4 and A5 . I bought two units so far thinking that either I broke it or it was doa. well turns out that both work fine. why is this info missing from the arduino site??
anyway thank you very much!
Thank you for this video.
I needed a refresh of what I already learnt in the past.
Good work !!
Thanks!
Thank you! This is really well done, clear and interesting!
thanks, appreciated from the Dominican Republic
You said 124 devices instead of 1024 devices (0:52 min), but great video it helped me alot, thanks :))
It saved me so much time and hassle. Good job!
Thank you brother, you help me a lot in my projects
Thank you for this useful video !! You explained the topic in such a clear way !!
Thank you very much for the clear explanation.
Good explanation of the protocols' packet. thanks
amazingggggg you did save me after reading datasheet for days
Omg, this is so good animation. Appreciate !
Nice work and thank you very much for providing these quality videos.
Thanks, I understand how it's work now :D It's will really help me :D
Great Tutorial,,,
Make more ..
Absolutely waiting for all your tutorials,,
A very clean and neat explanation... I understood clearly... Thank you very much.
Excellent tutorial bringing out the details very clearly
So easy to understand. Thank you!
Thanks Dejan for this great tutorial. It helps me a lot! :)
Accurate and up to the mark explanation thank you so much
Nice presentation along with a great explanation. Thank you, for sharing, Dejan!!
Great job of explanation ! Good graphics and clear explanation of the timing !
Thank you!
Thanks, it helped me a lot to understand how I2C works.

Thanks, very good in depth tutorial!
To the point, simple and clear, well done! which most people struggle to explain.
~This is coming from a Professional Embedded engineer.
Glad to hear it, thanks!
Verywell explained, clear, direct to the point, Thank you...
So well explained!!! Thanks. Subscribed.
Thanks man, I appreciate the video. I wonder what kind of issues you could run into if you ran 1024 10 bit devices on the same line. Electromagnetic interference may become a concern.
Thanks, really very clear explanation and very effective.
ΤΗΑΝΚ ΥΟU.. ! A VERY CLEAR EXPLANATION OF i2C DEVICES
Awesome tutorial thanks a lot where have you been where I didn't understand that communication at all.
Appreciate for your excellent video, you speak very clear and explain in detail! You are wonderful! Help a lot!
Nice ! Now i got a clear idea what is I2C.
Thank you for that simplified explanation :)
Glad it was helpful!
Great work. Can we also see somewhere the procession of raw data into actual measurements?
Do you use the sensor's librarys for that?
We want to connect a CO2 sensor, a humidity sensor and two accelerometers. Also a BMP180...
Thank you...
This channel never gets old
This is an amazing tutorial. Thank you very much.
Simple and lucid explanation... Thank you
Nice Work! Very clear and simple explanation!!
This was an informative and helpful video. I also liked how you explained with graphics. It made things easier to understand.Thank you and please keep doing more videos like this for beginners like me. Best regards.
Thanks, I'm glad to hear that!
Thank you very much buddy for your great illustrations :)
Excellent, easy to understand, very precise!
Nice explanation... the protocol I2c is very usefull, fast and need... Thank's for your time and information.
Very well explained, thank you very much!
Good to know how all this works. I've used the Linux i2c and SMbus userspace tools, but never really knew the hardware functionality behind it. GPU lighting is generally i2c and motherboard controllers use SMbus (both very similar though). Knew just enough to be dangerous and change RGB colors or monitor temps with a very light shell script and even shell functions. The OpenRGB project has the addresses for most hardware, including USB (mouse, keyboards, and some mobos use USB for communication to controllers).
Utterly informative video much appreciation 👍
Very good and clear explanations! well done!
Thanks for a great explanation. Would it be possible that you do a video of how the arduino commands on the IDE are converted to signals on the wires. I feel there is a disconnect between the protocol explanation at the beginning and the arduino program. Also if you can add a link to the other video that you mentioned as completion to this one
I2C Communication -- Demystified! Thumbs up.
Thanks for the great explanation. I see that the addresses for the I2C devices are predetermined by the manufacturer, so is address collision a common problem that you have to deal with when using this interface?
Perfect explanation. Thank you.
superb video mate. Explained it very easily.
Thank you very much for this detailed explanation. You made this topic easy to absorb. 🐣
Great and informative video! Thanks so much!
Thank you. It's simple to comprehend
explained perfectly. thanks!
Thank you sir
Your explanation very simple and clearly. Very useful to me . onces again thank you sir
Really awesome and helpful video!
Dejan how do you learn about all this stuff?
can you recommend some books or info sources regarding MPU 6050 and other sensors.
Very very good tutorial! I'm just wondering how you set these addresses? Are they already set on the devices or do the devices have inputs to set them?
very very fantsatic explaination,.. thank you so
much bro..
Amazingly well explained!
