2 hours of reading and then here comes this video where everything is well explained in under 10 minutes... You tube is spoiling me...
@thesauceboss5995 2 роки тому
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.
@mark879 7 років тому
Awesome video! I especially appreciated the protocol/packet breakdown. Thanks very much!
@kamuizero 7 років тому
What a great video! Very clear explanation and simple demonstration on how to use it. Thank you very much.

The bit sequence was so well explained that I had to print the screenshot of it for future reference.

This is so beginner friendly! Thank you so much. I used the same illustrations to make few students understand the same. :)
@nobodyspecial313 8 років тому
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!

@kiranbs5057 3 роки тому
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 .

@michaelvogt7787 7 років тому
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.

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!!!

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).

@michaelliles6755 8 років тому
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 sir Your explanation very simple and clearly. Very useful to me . onces again thank you sir
@suzesiviter6083 6 років тому
To clarify; the I2C lines are either high impedance or 0, you never drive the bus line high directly; that is achieved by de-asserting the '0' and letting the internal pull up resistors tie it to Vcc. The high impedance or low state on the bus prevents bus contention; that is a ground connecting to Vcc directly causing a short between any masters or slaves.
