Tutorial on I2C OLED Display with Arduino/NodeMCU

The very first program you write when you start learning a new programming language is : "Hello World!".
The program itself does nothing more than printing a “Hello World” text on the screen.
So, how do we get our Arduino to display the "Hello World!"?
In this video I will be showing you how to get started with the small 0.91 (128x32) and 0.96 (128x64) I2C OLED displays.
There are 100s of tutorials on the web explaining the same thing in different ways, but I couldn't find one that tells me all about the OLED display and how to use it in different scenarios. It took me some time to work it all out. So, I thought I should create a tutorial on what I have learned and combine all the features and ways the OLED displays can be used in our projects.

Best ever tutorial seen recently.... no one can explain more clearer

[@CrazyCoupleDIY]

Thanks 👍

[@kd4pba]

Having worked for one of the largest networking companies on earth, I am very used to writing documentation, and creating video tutorials. This is Very very well done. Very well explained and detailed. Very clear instructions with purpose and no confusing references. If you do get confused pick up some of the free docs for Ardunio to help fill in the blanks. I have worked with MC since I was in school years ago. Kudos on the video very well done! I Look forward to more!.

[@CrazyCoupleDIY]

Thanks a lot for the appreciation
It really helps me in getting motivated

Thanks for the education that the Arduino is limited to the high order 7 bits for the address. That was extremely helpful. Also the usage of the Mux was in great detail. Excellent videos.

[@CrazyCoupleDIY]

Thanks 👍

[@CrazyCoupleDIY]

Thanks 👍

[@notimeforyou9818]

I've already figured out the I2C oled thing, but still learned about the 7 bit addressing, font and image converter resources and the multiplexer by watching this - great video, keep up the good work, and thank you.

[@cloudsuck]

Your video is simply a breakthrough for me!! I had been struggling with many aspects regarding Arduino including display routine configuration. Thanks SO MUCH :)

Copied from Reddit:
As
someone who is also still learning about electronics and Arduinos I felt the
timing of this being posted was kind of funny and that I should chime in. Now
what's funny about it, for me at least, is that I just finished working with an
OLED on a NodeMCU ESP-12E after not having worked with one for at least a year
(the former being rigged to a Nano). Naturally, I needed a little bit of a
refresher but got it working.
With
that in mind, I saw this post and felt like the timing was right and I'd give
it a quick look since it's still fresh in my mind. To be honest, I didn't
actually expect much - I did my project, I learned plenty about OLEDs and got
them working, and honestly, there are just so many websites and videos out
there already and so much information that what could this video possibly do
for me?
I
was actually really surprised with this. Like I said, the proverbial market is
flooded with information - a plethora of blogs and videos on how to do stuff
like this, and most of them are difficult to read through or unpleasant to
watch. This guy gets it right. His editing and presentation are fantastic, his
video footage is good quality, and he has easy-to-read schematics he walks us
through. Not only that, he goes way above and beyond, showing us how to set up
multiple OLED screens together, how (and why) addresses work, how to use
multiplexers for many OLEDs, and concludes with talking points on the
advantages and disadvantages of using an OLED and common errors in setting them
up.
This
video is really well made and very helpful, and for anyone who is anywhere in
the "just learning" to "needing a refresher" range of skill
level, I couldn't recommended this more. I mean, I just did a project with an
OLED and refreshed myself but still learned some things from this video. This
is honestly the kind of stuff I want to see when I'm looking for refreshers on
something or to learn something new. Great job.

[@ianpritchard6375]

Great! ssd1306_128x64_i2c works!!
I use an Arduino Due .. and the key for me was telling me that - if I was using a *Mega* - then I should use terminals 20 and 21. The penny suddenly dropped. That works on the Due too.
The Due also has terminals SCL1 and SDA1 in the same position as they are on the Uno.. and they don't work for this. Nor does using A4 and A5 as many tutorials show. Need to use terminals 20 and 21 folks.
Also ..I goofed first time on the mixture of underscores and hyphens in the file names. Out of the box they don't match so need to go through those very carefully.
Thank you!!

[@basildouglas855]

Good day, I have just watched your video on connecting and programming the Oled display to an Arduino. I was absolutely stunned at your presentation. How you managed to fit a 10 episode course into a single 12 minute video, defy's logic. Of course I would like to be able to connect an Oleg to my Arduino and do the required programming and the necessary changes in the software. But sadly, I will not manage to do this from your video. I have no doubt whatsoever that you are talented and very proficient at what you do, but being a genius at something does not necessarily mean that you will also be skilled in conveying your talent to others. I want to share the following with you, years back, I was still a student pilot, and my instructor warned me about some instructors that are only interested in showing students how well they themselves can fly. I honestly believe that you should have another go at this video, back off from your brilliance, come down to our average level and do it again. There are thousands of us out there who can benefit. I've read some of the comments, most of them say nothing, they just throw you a bouquet. I am being honest here, guys like us need people like you, however, if all you are achieving is to sow confusion, then your video is pointless and a complete waste of time. Regards

[@CrazyCoupleDIY]

I truly appreciate an honest comment and a very good suggestion. I will make another one with absolutely no jargon in it. I will try to keep it as simple as I can and as easy to understand as it can be.

Great video. So far no one answered this. How can I use different pins? I am using D0-D7 for keypad on NodeMCU.

[@CrazyCoupleDIY]

First of all thanks for watching
Now, D1 and D2 on NodeMCU are SCL and SDA.
Which means if you are trying to use an I2C sensor it has to be on those pins unless you multiples it using a TCA9548A i2C MUX.
You can check out my tutorial number 9 for that: ua-cam.com/video/XWQsqPQOW-U/v-deo.html
Now, if you are running out of GPIO pins you need to extend your GPIOs using an IO extender. My next tutorial is on that only.
If you want you can check it out next week and that will for sure answer your question.
Using the i2c IO Extender you can extend the GPIO pins to have 128 'parallel' pins.
