/********************************************************************************
n this example, I've represented the smiley face emoji as a pixel pattern 
in a 1D array. The number "1" in the array represents the pixel color for
 the eyes and mouth, 
while "0" represents a blank pixel. You can modify the pattern array for
 different emojis by designing a 16x16 pixel art and converting it 
 into a similar 1D array format.

Note that for more complex emojis, you may want to consider using larger
LED matrices or multiple smaller matrices to ensure you have enough resolution to represent the details of the emoji accurately.
