It looks for an ASCII string of comma-separated values.
It parses them into ints, and uses those to fade an RGB LED.
- Circuit: Common-anode RGB LED wired like so:
- * Red cathode: digital pin 3
- * Green cathode: digital pin 5
- * blue cathode: digital pin 6
- * anode: +5V

Once you have programmed the Arduino, open your Serial minitor.
Make sure you have chosen to send a newline character when sending a message.
Enter values between 0-255 for the lights in the following format :
Red,Green,Blue.
+ Seriously: did you set the Newline setting in the monitor?

Once you have sent the values to the Arduino,
the attached LED will turn the color you specified,
