  // Increase the FAN PWM frequency. Removes the PWM noise but increases heating in the FET/Arduino
  //#define FAST_PWM_FAN
  
  // Use software PWM to drive the fan, as for the heaters. This uses a very low frequency
  // which is not as annoying as with the hardware PWM. On the other hand, if this frequency
  // is too low, you should also increment SOFT_PWM_SCALE.
  //#define FAN_SOFT_PWM
  
  // Incrementing this by 1 will double the software PWM frequency,

  #define SOFT_PWM_SCALE 0
  
  // If SOFT_PWM_SCALE is set to a value higher than 0, dithering can

   * RGB LED / LED Strip Control
   *
   * Enable support for an RGB LED connected to 5V digital pins, or
   * an RGB Strip connected to MOSFETs controlled by digital pins.
   *
   * Adds the M150 command to set the LED (or LED strip) color.
   * If pins are PWM capable (e.g., 4, 5, 6, 11) then a range of
   * luminance values can be set from 0 to 255.
   * 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.
