Connecting OLED Displays with Seeed Studio XIAO ESP32 C3 - With Code

This video covers how to use OLED displays (both without and with an I2C multiplexer) with your XIAO ESP32C3 board and provides the code for each scenario.
The first part goes over how to connect your displays without an I2C multiplexer, provides the code, what to change, what to take note of, and how to customize font. I show you the right and wrong ways of connecting displays, and the result of each case. I make the mistakes so you don't have to!
The second part goes over how to connect your displays to an I2C Multiplexer, and then to your XIAO ESP32C3 board. This video should give you everything you need to get started with your board and OLED displays!
At the very end is a quick clip of my soldering of the resistor / jumper for the address change of the OLED *which is optional*.
The link to download / copy the code for each use-case is featured on my Github repository here:

Download the ".ino" files (these are the Arduino code files/scripts needed to upload to your XIAO ESP32C3 board).

These videos are so good and well explained! Fun fact, if you don’t want to use a I2C multiplexer, and have a couple of the pins of the ESP32C3 unused, you can always use multiple I2C busses, and bit-bang all but the one which has the ESP32'S I2C hardware module internally attached. (note, bit-banging is slower though) This way you can control another 2 displays for every 2 pins you have available :)

Just found your channel and I love your content, the videos are concise yet exhaustive enough for beginners to get started !

[@Tasty_Light]

Your explanation is very simple yet elegant that anyone can understand easily. Amazing Rita 😊

[@robrietveld4099]

Very well explained, as an old computer engineer I love to see new a new generation pick up the baton. One small gripe, the deliberate video hiccups give me a headache but I guess that’s me being an old fogey. Anyway, well done!

Thanks so much...I learn something each time I view your videos. I believe this was my favorite. This little XIAO ESP32C3 board is so interesting. I became interested in the TinyML capabilities of this board after viewing your earlier video on this series boards.

another great video Rita keep them coming

[@goldstick3D]

Thank you for being back at making videos! Always great to see them. Why these specific boards though?

[@techwithrita]

These are just a few of the boards I have, I intend on making more videos for all the boards, devices, sensors and tech things I have… just to help others out there build creative things! Once we / people get over the hurdle of learning how to use things, that’s when magical creativity and ingenuity comes in! The world could use more fun, creative technological solutions, at least that’s what I think.

Nicely explained!

A great video by TechWithRita

[@bryanpaderes8963]

Thank you! By the way, you're looking great too!

[@Finer_Gross]

So I am bored and without much to do and I came across some small boards that I think I got at a yard sale or something…one of them is an ESP32-SOLO-1 “Espressif (maybe espressia)” I’m curious to know if there’s really anything I can do with it like? It looks like there’s an 8pin connector along the bottom of the bell shaped board…please reply any insight or suggestions.

Seriously 😮

What is the model of the CNC behind you?

[@techwithrita]

It’s just a generic 1610 with Uno ATmega328P

[@easy_3d]

You are so beautiful Rita

It's impossible to concentrate, either I see the project or I see her
