In all my years of programming I have never seen this:

display.println(F("Hello, world!"));

What the heck is the "F" for? I see it all over this OLED 1306 example code.

The Bald Engineer (awesome website BTW) has a great article on this, I generally refer people to it whenever I get this question:

It's very handy when debugging with a lot of Serial.print statements, I used it this week to debug the code for my next video.

Thanks Bill, would have never figured it out on my own and it actually makes sense.
