independantly dim two banks of LEDs

originally, thought i'd end standalone controller adjust photoperiod between 2 alternating sets of 3w leds, independently dim them , read , control lcd. i've come realize takes considerable talent , knowledge. heavy lift me alternating part sketched. absolute beginner here. anyway, here's have far.

int redled = 8;       
int redfan = 9;
int blueled = 10;
int bluefan = 11;
unsigned int minutesinms(int m){
return m*60000;                             //converts milliseconds minutes
}


void setup()                                    // run once, when sketch starts
{
  pinmode(redled, output);           // sets digital pins outputs
  pinmode(redfan, output);       
  pinmode(blueled, output);
  pinmode(bluefan, output);
}


void loop() {
  digitalwrite(redled, high);   
  digitalwrite(redfan, high);   
  digitalwrite(blueled, low);
  digitalwrite(bluefan, low);
 
  delay(minutesinms(300));
 
  digitalwrite(redled, low);   
  digitalwrite(redfan, low);   
  digitalwrite(blueled, high);
  digitalwrite(bluefan, high);
 
  delay(minutesinms(300));   
}

                                                                   // returns minutes in milliseconds

due limited coding ability, i've decided plug arduino computer change photoperiod. part's done.

would reasonably "easy" write code allow me plug arduino computer  , independently change dimming value on each set of leds , forgo lcd, buttons/pot? (it's not soldering parts that's killing me, it's supporting code)

any appreciated.

if so, know might find sketch might close need parts , learn from, or maybe point me in right direction?

run bit on timer variable toggled each time function called, i.e can turn them on/off or off/on

code: [select]

  digitalwrite(redled, high);   
  digitalwrite(redfan, high);   
  digitalwrite(blueled, low);
  digitalwrite(bluefan, low);

not sure mean dimming.  perhaps use analogwrite instead??

pc control, not hard if offload stuff (above) timer.

lcd panel

well start getting panel , find code work, integrate other code
