Seems to be worse when driving than idling
Don't have any other issues with the car? If i was you, i would look at cleaning up your main earths within the engine bay. Any bad earths (common the main battery earths are corroding up quite a bit now days) could be causing a bit of resistance and back feeding causing all sorts of other issues. You will find things like ECUs aren't too susceptible to this sort of thing as they are designed for a 'dirty' power source but the arduino is very basic and won't have this sort of protection (although could be added with ease)
