I want to use an array to control output values. What can I do?

Projects Programming

Here is what I have so far,
now the array pwmVals[] represents an 8 bit sine wave
which sets the valCount to 256

Each 'for loop' is designated to a different pin, to run through the values of 'i,' so that the array pwmVals[] will sequence through each pin - so I have declared "int brightness = pwmVals['i']"

example:

   for (int i = 0; i < valCount; i++); 
      {analogWrite(transistorPin2, brightness);
      delayMicroseconds(timer);}

Are there any inherent problems with that, or something else in my implementation?

int potPin = 0;
int timer = analogRead(potPin);
const int transistorPin2 = 2;
const int transistorPin3 = 3;
const int transistorPin4 = 4;
const int transistorPin5 = 5;
const int transistorPin6 = 6;
const int transistorPin7 = 7;
const int transistorPin8 = 8;
const int transistorPin9 = 9;
const int transistorPin10 = 10;
const int transistorPin11 = 11;
const int transistorPin12 = 12;
const int transistorPin13 = 13;

}

the result is just that all the pins are high. Any help would be enormously appreciated.
