Hello everybody, in this tutorial I’m using 128*32 i2c OLED display that I bought for few bucks, it’s very tiny you can use it in some small DIY projects also it gives you lot of possibilities to do (Different font and sizes of texts, different shapes, scrolling, bmp pictures…) and in this tutorial I just went through some simple functions to make it clear and simple for beginners like me… Please note that this kind of display isn’t a color display, mine just print in blue (Left), some are in white, some can have yellow + one of the previous colors (Right).
