Hi all,
I'm Jason and I am new to all this so please go easy on me. I am trying to make an array of LED's to replicate the indicators of a new Audi. I have put some code together out of examples on here and other sources.
I have sorted the sweep, and the colour, and I have 2 arrays one for the left and one for the right both operating from there own input. the problem Ihave is I need to activate both at the same time to indicate the Hazard warning lights.
Could any of you nice people have a solution to drive both arrays at the same time.
the LED arrays are WS2812b RGB strips.
here is the code.
Thanks
Jason.

//Now you can create a new .ino file with your IDE of choice (I've really been loving Sublime Text) and insert the starter code from the FastLED wiki:
#include "FastLED.h"
// fast led constants
#define DATA_PIN 3 // change to your data pin
#define COLOR_ORDER GRB // if colors are mismatched; change this
#define NUM_LEDS 20 // change to the number of LEDs in your strip
#define DATA_PIN1 5 // change to your data pin
#define COLOR_ORDER GRB // if colors are mismatched; change this
#define NUM_LEDS1 20// change to the number of LEDs in your strip
#define IN_1 10
#define IN_2 12
// change WS2812B to match your type of LED, if different
