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.”
