=== NOTICE ===

In order to use the newly purchased 0.96" OLED SD1306 display, I studied the u8g2 library and made this video to share with you on how to use U8g2 library with monochrome display. In the video, I also included a section on how to use the free 5000+ traditional Chinese font created by Mr. Yang. The file is free for anyone to use. Really appreciated what he did for Arduino community!

For those who do not have time to watch the entire video , here is the video timeline.
