I just woke up at 04:05 after 3 hours of sleep and im not even at home

So I am gonna tell you how to print some text on a 128x64 OLED display with arduino.

Step 1. Connect the display to your board. Make sure you have the board powered off before doing that. Also it will be much easier if you have a breadboard. Some people may be confused with VCC pin on the display, just connect it to 3.3v. If you're using a smaller board, like WEMOS D1 Mini, they usually dont type SCL and SDA pins on the board itself, just search up your board name and "pinout", look which pins have a little SCL or SDA mark, and connect them to the same pins on the display.

Step 2. Use Arduino IDE to write a sketch. idk who the hell came up with the idea of calling arduino projects sketches, that just means project file. Okay, first you need a good and fast library, and I recommend you GyverOLED, it is a library developed by a russian youtuber, and it works pretty fast on many other oled display variations. Install the library from the library manager. Now you see a prepared code with 2 empty functions, setup and loop. Do not delete them, if you did maybe try pressing ctrl+z or creating a new project. So, about the code...

Step 3. Actually coding. Right before the first function, write

#include <GyverOLED.h>

And on the next string write

GyverOLED<SSD1306_128x64, OLED_BUFFER> oled;

Now important moment. You can have a different display, if your program looks goofed, try replacing SSD1306 with SSH1106

Then, go inside the "setup" function and write

oled.init();

oled.clear();

oled.update();

The reason why you need to clear the display is because it just doesn't clear itself after rebooting. And remember that you have to write oled.update() after every time you put something on the screen, else it just will not display on there.

Now you see that i left 1 line blank, it wasn't by accident. Go on this line and type

oled.print("Your text");

Of course you can replace the example text with what you need.

You can read the library documentation on github to explore more functions, just type gyveroled in google

So the full code should look like this:

#include <GyverOLED.h>

GyverOLED<SSD1306_128x64, OLED_BUFFER> oled;

void setup() {
    oled.init();
    oled.clear();
    oled.print("Hello, NG!");
    oled.update
}

void loop() {

}

You see we left the second function empty. Thats because setup function runs only once after booting up, and loop repeats over and over again, and we only need to print one string just once.

Now connect your board to your pc and GO SMASH THAT UPLOAD BUTTON

Ask questions if something didnt work, comments are always opened, now have a good night lmao

its 05:02. i am screwed...
