Tutorial on I2C OLED Display with Arduino/NodeMCU 

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!.

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

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.

Now, this is how a tutorial is done!!

OUTSTANDING tutorial. Well done videography too. After hours and hours researching to find the answers, you said it all in less than 17 minutes. Thank you Crazy Couple. Thumbs and new subscriber.

Fantastic tutorial. The closing wrap up with Common Errors was a bonus. Clear concise and informative. Thanks !!

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

Just dipping into Arduino and NODEMCU world and your very clear explanation was exactly what I needed. Thanks!

This is gold, just an amazing all in one presentation

excellent presentation... no nonsense and straight to the point... easy to understand too... good job on the tutorial...

Thank you, for a very clear guide how to use these Oled displays, it's just what i needed.

hands down best video about oled displays and common display knowledge. Thanks!

I have to agree with Laszlo, this is the most inclusive tutorial I've seen Thanks for your work.

Well explained and engaging The pace is very good and u covered almost everything in this tutorial Amazing, keep it up

This is simply OUTSTANDING! Thank you very much!

Thank you for a great tutorial. Concise and exactly what I needed to know

This is one thorough, clear and very well done video. Thanks a lot.

Thank you. This is one of the best detailed tutorial I ever watched.

This is the video to keep in your library.

Fantastic!!! One of the best tutorials I've seen.

Definitely worth the watch, thank you for the video, well made 👍

Well done, great thorough inclusive explanation of everything!

The best tutorial I have seen for oled. So thorough. Thanks a bunch. great work Keep it up. I subscribed, It is rare when I do.

Well done ! Great tutorial for the beginners. I just looked something like that. All The Best !

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.

You did a very good job on this video. It is very clear and complete. When I am about to hook up my OLED I will use your video as my reference. Thanks for the great lesson.

WTF! In these 16 minutes I've learned more about displays and communication than ever before in a few days :-D. Thanks buddy!!! And btw, very good and clear english. Perfect for me as a native german :-)

very complete, detail oriented, and concise delivery...thx

Nicely compiled, well done. I have subbed

This tutorial is legitimately amazing. Thanks so much!

This is great, one stop shop for everything

Sir thank you for this tutorial, is awesome! thank you for taking the time to do this!! You rock!

WOW. Thank you! I got mine working thanks to your video. I subscribed! Keep up the good work!

What a superb instructional video. Thank you and keep them coming

Thanks a million for this! Everything worked perfectly, the first time, including multi-display!

good job, made the whole task look so simple, tutorial very much appreciated!

Ottime spiegazioni che mi hanno fatto proseguire nel mio progetto. Grazie!

Best tutorial I have ever scene

Thank you for making this! It was very helpful and informative.

Amaizing presentation

respect for your work CRAZY COUPLE, u did this tutorial so well, wow!

Beautiful just beautiful, thank you so much!!

literally the best tutorial ever! Now i know everything i need to know!

Thank you - Very comprehensive - well presented.

That was really a great imstructive! Thank you!

Very good explanation. Sufficient for a beginner. Worked for me

You convinced me to buy a multiplexer and also a node mcu lol. Great tutorial!

wow really very nice tutorial ...

really usefull and clear cut explanation . THANK YOU BRO

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!!

Terrific video. This was very informative and clear.

very well explained and in details. i spent numerous hours trying to get my OLED to work , stumbled upon this video and found out my OLED address was incorrect.

Informative and to the point. Great job👍🏻

great instructions, very clear and complete.

Thank you very much for the video, very clear. Kind regards from Argentina

very clear and concise :) great work

great videos and tutorials! thank you!

Very nice and easy to follow....thanks

Really really nice tutorial. Very compact source of information. One small hint: its not a zero (0) Ohm resister. Its 472 printed on, which is 4,2 kOhm

Excellent tutorial. Subscribed!

Such a good explanation. Good job

Very good tutorial and information, keep posting

best tutorial ever

Thank you for this amazing Video!

Excellent work. Very helpful information. Thanks

can we use different pins(except D1 and D2 for nodemcu esp8266, and A4 and A5 for arduino) for oled display

Brilliant job. Thank you!

Perfect!! And THAT is a good tutorial!

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.

Hello from India....Thanks a lot for creating such an informative tutorial with every bit of details...appreciated. Liked Subscribed.

Hi I have a question if my esp8266 connected to WiFi how can i display the IP Address on OLED i used the esp 8266 library SSD1306Wire not the Adafruit for the OLED thanks in advance if you can advise on the exact code also for MAC address

Best tutorial ever

I know this is an older video but when running on an Uno R3 you may need to change 0x3D to 3C to get it to work

Very good explain

The Best explain on RU-vid!

sir i making a project smart glasses , but facing problem with connection of bluetooth hc 05 with Retro watch application what should i do????

Thanks bro Your works is amazing

Absolute genius, must :)

Thanks it's verry helpful vor my projects 😉

Keep it up, nice video, thank you for sharing it :)

are those libraries arduino dependent? in other words AVR code? Cant use it with an ARM based micro-controller of another brand?

great video

cannot get it working with this code, do i need to modify wire.h to declair the sda and scl pins?

Very nice Thanks a lot

Excellent video man!

great info
