Check ARCADA_LEFTTFT_SPI rather than ADAFRUIT_MONSTER_M4SK_EXPRESS to enable second eye
ARCADA_LEFTTFT_SPI is normally only defined on Monster M4sk but a custom Arcada config can override this and allow 2 eyes on other boards.
#define GLOBAL_INIT(X)
#endif
-#if defined(ADAFRUIT_MONSTER_M4SK_EXPRESS)
+#if defined(ARCADA_LEFTTFT_SPI) // MONSTER M4SK or custom Arcada setup
#define NUM_EYES 2
- // Light sensor is not active by default. Use "lightSensor : 102" in config
+ // MONSTER M4SK light sensor is not active by default.

#else
#define NUM_EYES 1
