config for uncanny eyes & Itsy Bitsy

	// Pin selections here are based on the original Adafruit Learning System
	// guide for the Teensy 3.x project. Some of these pin numbers don't even
	// exist on the smaller SAMD M0 & M4 boards, so you may need to make other
	// selections:

	// GRAPHICS SETTINGS (appearance of eye) -----------------------------------

	// If using a SINGLE EYE, you might want this next line enabled, which
	// uses a simpler "football-shaped" eye that's left/right symmetrical.
	// Default shape includes the caruncle, creating distinct left/right eyes.
