I’m writing code using the ColorPalette example, is there any way to make the movement of the LEDs slower? I know that I can lower the updates per second, but that also sacrifices smoothness. I would like the palettes to move about half as fast along my LED strip.

if( lastSecond != secondHand) {
  lastSecond = secondHand;
  if( secondHand ==  0)  { currentPalette = RainbowColors_p;         speed = 20; scale = 30; colorLoop = 1; }
  if( secondHand ==  5)  { SetupPurpleAndGreenPalette();             speed = 10; scale = 50; colorLoop = 1; }
  if( secondHand == 10)  { SetupBlackAndWhiteStripedPalette();       speed = 20; scale = 30; colorLoop = 1; }
  if( secondHand == 15)  { currentPalette = ForestColors_p;          speed =  8; scale =120; colorLoop = 0; }
  if( secondHand == 20)  { currentPalette = CloudColors_p;           speed =  4; scale = 30; colorLoop = 0; }
  if( secondHand == 25)  { currentPalette = LavaColors_p;            speed =  8; scale = 50; colorLoop = 0; }
  if( secondHand == 30)  { currentPalette = OceanColors_p;           speed = 20; scale = 90; colorLoop = 0; }
  if( secondHand == 35)  { currentPalette = PartyColors_p;           speed = 20; scale = 30; colorLoop = 1; }
  if( secondHand == 40)  { SetupRandomPalette();                     speed = 20; scale = 20; colorLoop = 1; }
  if( secondHand == 45)  { SetupRandomPalette();                     speed = 50; scale = 50; colorLoop = 1; }
  if( secondHand == 50)  { SetupRandomPalette();                     speed = 90; scale = 90; colorLoop = 1; }
  if( secondHand == 55)  { currentPalette = RainbowStripeColors_p;   speed = 30; scale = 20; colorLoop = 1; }
}

Look how this example works, and I think you will understand!

It is not easy to answer without more details.

If you can somehow make the changes (or steps) between each update 50% smaller and keep your updates per second the same, you will end up with a smooth animation that is 50% slower !!
