Color guide: https://www.rapidtables.com/web/color/RGB_Color.html

Challenges:
1) Make sure servo motor works by testing 0,90,180
2) Get servo motor to cycle between 0,90,180
3) Get servo motor to cycle between 0-180 with resolution 6
4) Get servo motor to cycle between 0-180 with resolution 10
5) Control #4 with potentiometer
6) Get servo motor to cycle between 0-180 with resolution of 7.  As you change angles, 
cycle through rainbow colors
