new project hula hoop

Postby Banya1987 » Mon Oct 15, 2018 10:05 am

I am currently working on an LED hulahoop project and during the research how to program in Arduino I find this website and ,My question is how can I put more pattern into this code?

#include <Adafruit_NeoPixel.h>

//IMPORTANT: Update the pin and length to match your LED strip!
#define PIN 5
#define LENGTH 150

Adafruit_NeoPixel strip = Adafruit_NeoPixel(LENGTH, PIN, NEO_GRB + NEO_KHZ800);
int pixels = 15;
int frames = 100;
int fps = 30;

//This data array is a R, G, B values in sequence. The pixels from the first frame are first, followed by the next frame, etc..
//We're storing this in PROGMEM (see note below) to save space in RAM which is normally more constrained
const byte data[] PROGMEM =
