Code:
/*
* Made by KinCony IoT: https://www.kincony.com
*
* This Arduino program demonstrates how to display text on an SSD1306 128x64 OLED display using the U8g2 library.
* The program draws two lines of text on the display:
* - The first line is "KINCONY" in a larger font.
* - The second line is "www.kincony.com" in a smaller font.
*
* The display is connected via I2C (software implementation) with:
* - SCL (clock) on pin IO18
* - SDA (data) on pin IO8
*
* The display's I2C address is set to 0x3C.
