درود دوست عزیز نصب راحتی داره شما میتوانید از کتابخانه زیر کمک بگیرید
Adafruit NeoPixel و کتابخونهٔ fastLED
دوپین (+5 =VDD) و پین (VSS = Ground ) که معلومه چطور وصل میشند میمونه اخرین پین ( Di ) که شما از ماژول led که با ی مقاومت 470 اهم به پین دیجیتال 6 اردینو وصل میکنید طبق تصویر
در ضمن ( Do ) برای بشتر کردن طول این ریسه میباشد
و در اخر اینم دو کد زیبا برای شما دوست عزیز
کد:
#include <Adafruit_NeoPixel.h>

// Parameter 1 = number of pixels in strip
// Parameter 2 = pin number (most are valid)
// Parameter 3 = pixel type flags, add together as needed:

// 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)
