/*
    Object RGB
 
    Intent: Light up a single RGB LED according to three colour inputs, directly to the hardware,
    Interface:
        Language is 
            Low =0, converted at on() stage
            Three colours: between 0 to 255 - 255 means on, 0 meean off
            durations in milliseconds
            Ngradation of colour
        Hardware
            Three digital Hardware Pins
            Translate From Hardware - High as a parameter need to be convered to LOW as an input to the hardware
    Usage: First setPins, then repeatedly (setColour or NextColour, then switch on or shine to illuminate) then off. the LED
    Choices:
        Assume a differenet HW light for indicators, and headlamps etc. Heep it simple and separate hardware
        retain colour even if off
