hello, i need your help. my led strip only displays white. what i’m doing wrong?
thanks in advance.

// RGB Calibration code
//
// Use this sketch to determine what the RGB ordering for your chipset should be. Steps for setting up to use:
// * Uncomment the line in setup that corresponds to the LED chipset that you are using. (Note that they
// all explicitly specify the RGB order as RGB)
// * Define DATA_PIN to the pin that data is connected to.
// * (Optional) if using software SPI for chipsets that are SPI based, define CLOCK_PIN to the clock pin
// * Compile/upload/run the sketch
// You should see six leds on. If the RGB ordering is correct, you should see 1 red led, 2 green
// leds, and 3 blue leds. If you see different colors, the count of each color tells you what the
// position for that color in the rgb orering should be. So, for example, if you see 1 Blue, and 2
// Red, and 3 Green leds then the rgb ordering should be BRG (Blue, Red, Green).
// You can then test this ordering by setting the RGB ordering in the addLeds line below to the new ordering
// and it should come out correctly, 1 red, 2 green, and 3 blue.
