Example_03_BitMap_MOD_Water_Droplet.ino

/*
  Example-03_Bitmap_MOD_Water_Droplet.ino

  This demo shows how to write a converted monochrome bitmap on the display.
  We scaled and converted open source emoji's down to fit the size of the OLED. 
  The chosen bitmaps will be used with the Qwiic Soil Moisture Sensor.  
  
  Note: Make sure to be careful about adding too many bitmaps. You may run out
  out of memory!

  This library configures and draws graphics to OLED boards that use the
  SSD1306 display hardware. The library only supports I2C.

  SparkFun sells these at its website: www.sparkfun.com

// Let's draw a truck - use our built in bitmap

//#include "res/qw_bmp_sparkfun.h"
#include "icon.h"  //.h file to hold the converted images.
