Arduino kod i video za SSD1306 OLED 128 x 64 ekran

/*
 * Original source: https://github.com/adafruit/Adafruit_SSD1306
 * This is the Arduino code for the SSD1306 OLED 128 x 64 Display.
 * Watch the video for details and demo: http://youtu.be/UmYiHTOz-5k
 * This code has been modified to print specific elements such as text, lines, circles, rectangles, etc.
 * I have added a custom method to make printing text easy.
 
 If you get the error: Adafruit_GFX.h not found, download the Adafruit-GFX Library from:
 https://github.com/adafruit/Adafruit-GFX-Library

 Purchase this OLED module from Amazon: https://amzn.to/36zFvTb

/*********************************************************************
This is an example for our monochrome OLEDs based on SSD1306 drivers.

  Pick one up today in the Adafruit shop!
  ------> http://www.adafruit.com/category/63_98

This example is for a 128x64 size display using I2C to communicate.
3 pins are required to interface (2 I2C and one reset).
