OK, I was given a Arduino and breadboard for my birthday, but have no clue about electronics....good start right (was given its as im intrested in programming, not electronics)
I have been trying to interpret simple, but am having loads of trouble with GND (Ground, right?), now is this just the returned path to the batteries +V , or dose it need to be attached to the case?
the most experience i have has is is playing about with LEDs and motors and have never really come across GND or real systematics.
Im very keen to get the basics sown before i even take out the Arduino out the box!

Yes, your first impression is correct, it is just the return current path to the voltage source whether battery or DC power module. A better term in my opinion is 'common' or 'circuit common' as 'ground' tends to imply a connection to an earth ground somewhere and that is not necessarily true or even required. Having and using a true earth ground is usually done as a safety design for voltages that are high enough to cause injury. An earth ground can also help improve radio frequency transmission and reception but that is a whole other subject.
