Outcome

• Modify the code to light up pixel by pixel then reverse the sequence turning each pixel off one by one
• Modify the code to light up blue, then red, then green then white in sequence
  
• Change the code to only light up only one pixel at a time. With each loop move that pixel one position higher. When it reaches the final pixel, restart the sequence at zero i.e. build a single pixel that will continually cycle
  
• Add three Particle.function to set the Red, Green and Blue components. Allow these values to be set from 0-255 and as they are set to change all of the pixels on the LED strip to that color.
