Hi all, I'm a newbie in arduino. Currently, i'm working for my final year project. I have 3 led strips hooked to a single arduino Uno board. How can I change the color for each strip differently? I mean for the 1st strip is blue, 2nd is green, and 3rd is red. I pasted together the code here.
Hope that someone can help me out as I'm totally helpless when it comes to programming.
#include <Adafruit_NeoPixel.h>

#define CLK_a 2 //Set the CLK pin connection to the display
#define DIO_a 3 //Set the DIO pin connection to the display
#define CLK_b 8 //Set the CLK pin connection to the display
#define DIO_b 9 //Set the DIO pin connection to the display
int NumStep_a = 0; //Variable to interate
int NumStep_b = 400; //Variable to interate
TM1637Display display_a(CLK_a, DIO_a); //set up the 4-Digit Display.
TM1637Display display_b(CLK_b, DIO_b); //set up the 4-Digit Display.
#define PIN_5 5

// Parameter 1 = number of pixels in strip
// Parameter 2 = pin number (most are valid)
// Parameter 3 = pixel type flags, add together as needed:
// NEO_KHZ800 800 KHz bitstream (most NeoPixel products w/WS2812 LEDs)
// NEO_KHZ400 400 KHz (classic 'v1' (not v2) FLORA pixels, WS2811 drivers)
// NEO_GRB Pixels are wired for GRB bitstream (most NeoPixel products)
// NEO_RGB Pixels are wired for RGB bitstream (v1 FLORA pixels, not v2)
