Hello Does anyone know how can I make a stripe in various colors lights and can control this by using a potentiometer. So, for example, Red through Poti to blue with all the shades of purple between there. And the same with the other colors?

This has been discussed an answered, with code and electronic help just in the last week or two. If you just look back or search on potentiometer, you will find it

Are you trying to make an rgb color mixer with three potentiometers? Or something different? What have you tried so far? You can post code to http://pastebin.com to make it easier to follow.

Maybe im to stupid … but i did not find any Code with Potentiometer here … I only need to get the Stripe in a Static Colour .

Like Blue or Something . All Codes i find are going to make Dico

Here’s an example I made awhile back. Using two potentiometers to control hue and brightness.

//===============================================================
// hue_and_brightness_example.ino
//
// Example setup for using two potentiometers to control hue and
// brightness with FastLED.
//
// Every time the function checkKnobs() is called it will read
// the current value of both potentiometers and map those values
// to a hue and master brightness for FastLED.
//
// Marc Miller, 2015
//===============================================================

#include "FastLED.h"
#define LED_TYPE NEOPIXEL
#define DATA_PIN 6
#define NUM_LEDS 12
#define MASTER_BRIGHTNESS 255  // Set the master brigtness value [should be greater then min_brightness value].
uint8_t min_brightness = 30;   // Set a minimum brightness level.
uint8_t brightness;            // Mapped master brightness based on potentiometer reading.

@Stuart_Taylor also shared an example of controlling hue with a potentiometer that you might be able to search out.
