Scale the brightness value of all three RGB colors with one value, 0 to 255 (0 is 0%, 255 is 100%). This setting persists after
RGB.control() is set to
false, and will govern the overall brightness of the RGB LED under normal system operation. User must take control of the RGB LED before calling this method.
// Scale the RGB LED brightness to 25% RGB.brightness(64); // Scale the RGB LED brightness to 50% RGB.brightness(128); // Scale the RGB LED brightness to 100% RGB.brightness(255);
