Programming Question

[system]

Hi All,
I have a programming question, probably simple to some... (but not for me)

I have set up my Arduino with 6 leds (outputs = 3,5,6,9,10,11) for PWM on my breadboard. That is ok.

What I would like to do is have a program that increases the led intensity like a bell curve moving like a wave front down the line of leds. I would like to have that wave loop continously.

In other words, I am trying to set up the led intensities to scroll or loop (i=intensity, i, i+1, i+2, i+3, i+3, i+2, i+1, i). I am little baffled on how to have this loop around.

how about something like this:

unsigned char bellcurve[8];
int pins[6] = {3,5,6,8,10,11};
int startpos = 0; // which item from bellcurve goes on first LED.

calculate_intensities();  //fills in bellcurve
  bell_idx = startpos;
for (i=0; i < 6; i++) {   // output bellcurve (part) to LEDs
  if (bell_idx > 7)
    bell_idx = 0;
  analogWrite(pins[i], bellcurve[bell_idx]);
  bell_idx += 1;
}
