Fading the LED without turning it off.

hi, guys. i'm noob in arduino now.

i wonder, how can turn on led, using fade-effect. without turning off.

i use

code: [select]

int pwmpin = 10; // led in series 470 ohm resistor on pin 10

void setup()
{
}

void loop()
{
  (int i=0; <= 255; i++){
     analogwrite(pwmpin, i);
     delay(10);
  }
}

but, after fading in, led turnes off , fade in again , again , forever. , other commands in code(after for-commands) don't work. how prevent turning off, until 'analogwrite(pwmpin, 0)' command.

thank you.

if " " equals 0 or if required minimal voltage not met, turn off.
