arduino + openFrameworks + ledPin as output

hello, working on project 3 timers @ where:
1/ 1st timer started- ledpin not light up
2/ 2nd timer started (and 1st timer finished) - ledpin fading in
3/ 3rd timer started (and 2nd timer finished) - ledpin on

i using ofserial connecting sensor of, , working perfectly.
my ledpin lighting gradually ignoring code. may ask if arduino or of code not working please? or should not use ofserial firmata in first place?

arduino code:

code: [select]


  #include <firmata.h> 
  #include <capacitivesensor.h>

byte sensorbyte;
int inputpin = 4;
capacitivesensor   sensorpin = capacitivesensor(inputpin,2); 
int ledpin = 11;
int ledvalue;


void setup() {
     sensorpin.set_cs_autocal_millis(0xffffffff);
     serial.begin(9600);
     pinmode(ledpin, output);   
}

void loop() {
    sensing();
    byte ledvalue;
   
    if(serial.available()){   
      ledvalue = serial.read();     
      analogwrite(ledpin, ledvalue);
      delay(10);
    }
}

long sensing(){
long total1 = sensorpin.capacitivesensor(10);

sensorbyte = map(total1, 0, 170, 0, 255);
sensorbyte = constrain(sensorbyte,0,255);

serial.write(sensorbyte);

delay(10);   
}

code: [select]

    (int = 0; i< 255; i++){
        serial.writebyte(i);
        cout << << endl;
    }
how long going take execute loop?

code: [select]

    if(serial.available()){   
      ledvalue = serial.read();     
      analogwrite(ledpin, ledvalue);
      delay(10);
    }
how long going take read 255 bytes other code sent?

which going take longer? going happen when serial buffer on arduino fills up?
