      2  * PROGMEM Image Viewer
      3  * This is a simple PROGMEM bitmap image viewer example
      4  * Image Source: https://support.arduino.cc/hc/en-us/articles/360020652100
      5  *
      6  * How to create custom image:
      7  * 1. Open image ith GIMP
      8  * 2. Export Image as C-Source
      9  * 3. Uncheck all option and check "Save as RGB565 (16-bit)"
     10  * 4. Revise exported file just like "Arduino_UNO_Rev3_Ok.c"
