    BUG (believe I fixed it): when calling stopBlinking, if the light is off, won't turn on because it won't be queried during updateBlinkingLights. 
    Or, something else may be going on. Seems like it sometimes gets one more update. 
    
   Functionality test:
    increment/decrement buttons
    rainbow
    random
        
    Concerned that I may have now run it out of memory again...
