Hi
When I look at this circuit it seems that both motor terminals are connected to 5v and when the transistor opens it then allows one of the motor terminals to ground.

But when I look at other examples they seem to have a more common theme of one of the motor pins going only to the collector like this example:

The first example seems weird to me.
Is one more desirable than the other?
Thanks
