I downloaded the stair lighting code from the internet and modified it to match my stairs.
I would like to add a button to the existing code that would change the mode and some kind of "party mode"
I am an absolute noob to coding, and I believe that something like this is very simple for some of you.
So if someone is willing to write the code in existing ino file for me
Thank you in advance
<#include <Adafruit_NeoPixel.h>
#define PIN 6
// Parameter 1 = 321
// Parameter 2 = Arduino 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)

// pixel power leads, add 300 - 500 Ohm resistor on first pixel's data input
// and minimize distance between Arduino and first pixel. Avoid connecting
// on a live circuit...if you must, connect GND first.
