If I un-comment the Serial.begin(). The LED strip will no longer output signal to the LPD6803 led strip I have.

Can anyone look over and see why there might be a conflict? The code is at bare minimum as shown. So not much is going on.

I never thought I would find myself typing these words, but, what the heck, here goes - Way too much comment.

Yes, I know. It just happens to be my way to divide things up so that I can glance quickly for sections. Yes I do use tabs. One my my projects, which involves RS232, Ethernet, PHP, SdCard, Analog sensors, and button inputs, I found using this format makes it easy for me to find different areas of code when I am quick scrolling.

Great - I'm glad it's working for you.
For me, it's noise.

Back to the original question at hand. What where might there be a conflict with the Serial, vs what the Pixel Color (by way of LPD6803.h) be?

No comment version:

#include <TimerOne.h>    // I Dont think this is needed. 
#include "LPD6803.h"



int dataPin = 2;       // 'yellow' wire
int clockPin = 3;      // 'green' wire

// Set the first variable to the NUMBER of pixels. 20 = 20 pixels in a row
LPD6803 strip = LPD6803(50, dataPin, clockPin);


void setup() {

  // The Arduino needs to clock out the data to the pixels
  // this happens in interrupt timer 1,
