 * For Neopixel LED an overall brightness parameter is also available.

 * *** CAUTION ***
 *  LED Strips require a MOSFET Chip between PWM lines and LEDs,
 *  as the Arduino cannot handle the current the LEDs will require.
 *  Failure to follow this precaution can destroy your Arduino!
 *  NOTE: A separate 5V power supply is required! The Neopixel LED needs
 *  more current than the Arduino 5V linear regulator can produce.
