+  BlinkRGB
+
+  Demonstrates usage of onboard RGB LED on some ESP dev boards.
+
+  Calling digitalWrite(RGB_BUILTIN, HIGH) will use hidden RGB driver.
+    
+  RGBLedWrite demonstrates controll of each channel:
+  void neopixelWrite(uint8_t pin, uint8_t red_val, uint8_t green_val, uint8_t blue_val)
+
+  WARNING: After using digitalWrite to drive RGB LED it will be impossible to drive the same pin
+    with normal HIGH/LOW level
