WS8211B LED Strip control Via Blynk

Good Afternoon,

I am currently working with an Arduino Nano, A ESP8266 wifi Chip, and Blynk on Andriod 7.1.1
Blynk Server Library 2.18.1

I need some help getting some base code set and then hopefully I can continue off that,

What I would like to do is be able to control my LED strip by changing the color as well as being able to set patterns on the go.

there are a few example sketches that I would like to pull some palettes from.

• Add your sketch code. :point_up:Code should be formatted as example below.

Simply paste your code between ``` If you don’t format your code, your topic can be deleted by moderators.

#include <FastLED.h>

#define LED_PIN     6
#define NUM_LEDS    240
#define BRIGHTNESS  64
#define LED_TYPE    WS2811


void setup()  delay( 3000 ); // power-up safety delay
    FastLED.addLeds<LED_TYPE, LED_PIN, COLOR_ORDER>(leds, NUM_LEDS).setCorrection( TypicalLEDStrip );
    FastLED.setBrightness(  BRIGHTNESS );
    currentPalette = RainbowColors_p;
    currentBlending = LINEARBLEND;

void loop()
    static uint8_t startIndex = 0;
    startIndex = startIndex + 1; /* motion speed */
    FillLEDsFromPaletteColors( startIndex);;
    FastLED.delay(1000 / UPDATES_PER_SECOND);

void FillLEDsFromPaletteColors( uint8_t colorIndex)
    uint8_t brightness = 255;
    for( int i = 0; i < NUM_LEDS; i++) {
        leds[i] = ColorFromPalette( currentPalette, colorIndex, brightness, currentBlending);
        colorIndex += 3;

Currently, this code just loops through all of the palettes I would like to control the palettes via a separate button in blynk and also have an all off button option. I would also like the ability to make the whole strip a solid color with a color wheel. If parts of code have been written else where please don’t hesitate to point them out to me.

Thank You for your assistance,
