Good Day All,

I did a DIY led build using steves leds. Total led power 400watt. Now I want to code my RA so that I can do Thunder storms and clouds... Is this possible? :mrgreen:

If the Steve's LED's are capable of it (I'm assuming they are) here is a thread on the topic.

Here is Roberto's post...

Something like this:
Code: Select all
#include <ReefAngel_Features.h>
#include <ReefAngel_Globals.h>
#include <ReefAngel_Wifi.h>
#include <Wire.h>
#include <OneWire.h>
#include <Time.h>
#include <DS1307RTC.h>
#include <ReefAngel_EEPROM.h>
#include <ReefAngel_NokiaLCD.h>
#include <ReefAngel_ATO.h>
#include <ReefAngel_Joystick.h>
#include <ReefAngel_LED.h>
#include <ReefAngel_TempSensor.h>
#include <ReefAngel_Relay.h>
#include <ReefAngel_PWM.h>
#include <ReefAngel_Timer.h>
#include <ReefAngel_Memory.h>
#include <ReefAngel.h>

void setup()
{
    ReefAngel.Init();  //Initialize controller
    randomSeed(analogRead(0));
}

void loop()
{
    ReefAngel.ShowInterface();
    if (second(now())==0) StandardThunderstorm(); else ReefAngel.PWM.SetDaylight(0);
}

void StandardThunderstorm()
{
  byte value=random(255);
  ReefAngel.PWM.SetDaylight(value);
}
