البرمجة

أولا: التحقق من ضبط وحدة ساعة الوقت الفعلي و طباعة الوقت على شاشة الإتصال التسلسلي من خلال رفع الشفرة البرمجية التالية

#include <RTClib.h>
#include <Wire.h>
RTC_DS3231 rtc;
char t[32];
int dtminutes;
int dthours;
int minutes;
int hours;
void setup()

{
  Serial.begin(9600);
  Wire.begin();
  rtc.begin();
  rtc.adjust(DateTime(F(__DATE__),F(__TIME__)));
  //rtc.adjust(DateTime(2019, 1, 21, 5, 0, 0));
}
void loop()
{ DateTime now = rtc.now();
  sprintf(t, "%02d:%02d:%02d %02d/%02d/%02d", now.hour(), now.minute(), now.second(), now.day(), now.month(), now.year());  
  Serial.print(F("Date/Time: "));
  Serial.println(t);
  delay(1000);
}

ثانيا : التحقق من التحكم بشريط الثنائي المشع للضوء من خلال رفع الشفرة البرمجية التالية 

#include <FastLED.h>

#define LED_PIN     5
#define NUM_LEDS    64
#define BRIGHTNESS  140
#define LED_TYPE    WS2811
#define COLOR_ORDER GRB
CRGB leds[NUM_LEDS];

CRGB Colors [13]{CRGB::Gray,CRGB::Orange,CRGB::Maroon,CRGB::Red,CRGB::Cyan,CRGB::Lime,CRGB::Green,CRGB::Purple,
                     CRGB::Yellow,CRGB::White,CRGB::Blue};

void setup() {
    delay( 3000 ); // power-up safety delay
    FastLED.addLeds<LED_TYPE, LED_PIN, COLOR_ORDER>(leds, NUM_LEDS).setCorrection( TypicalLEDStrip );
    FastLED.setBrightness(  BRIGHTNESS );
    
}

void loop()
{
for (int j=0;j<13;j++)  
  for (int i=0;i<65;i++){
    leds[i]=  Colors[j];
    FastLED.show();
    delay(50);
    leds[i]=CHSV( 0 , 0, 0);
    FastLED.show();
  }
}

شرح البرمجة 

نبدأ بتحميل المكتبات شرح طريقة تحميل المكتبات من خلال الرابط

#include <FastLED.h>                     
#include <RTClib.h>
#include <Wire.h>

نعرف المتغيرات قيمة كل متغير ظاهرة حسب اسم المتغير

#define LED_PIN     5
#define NUM_LEDS    65
#define BRIGHTNESS  200
#define LED_TYPE    WS2811
#define COLOR_ORDER GRB
CRGB leds[NUM_LEDS];
RTC_DS3231 rtc;
int minutes;
int hours;
CRGB Colors[11]{CRGB::Chartreuse,CRGB::Orange,CRGB::BlueViolet,CRGB::Red,CRGB::Cyan,CRGB::Pink,
CRGB::Green,CRGB::Purple,CRGB::Yellow,CRGB::White,CRGB::Blue};

في دالة (setup) نكتب أوامر التهيئة الرئيسية الخاصة بشريط الثنائي المشع للضوء و وحدة الوقت الفعلي

void setup()
{
delay( 3000 );
FastLED.clear() ;
Serial.begin(9600);
Wire.begin();
rtc.begin();
rtc.adjust(DateTime(F(__DATE__),F(__TIME__)));
FastLED.addLeds<WS2812, LED_PIN, RGB>(leds, NUM_LEDS);
  FastLED.setBrightness(  BRIGHTNESS );
//rtc.adjust(DateTime(2019, 1, 21, 5, 0, 0));
}

سنقوم بعمل ثلاث دوال واحدة تعمل على التحكم بثنائي المشع للضوء الخاص بالساعات
وواحدة للتحكم بثنائي المشع للضوء الخاص بالدقائق
وواحدة للتحكم بثنائي المشع للضوء الخاص بكل من ( إلا / و)
