Should all grounds go to the same negative bus on a breadboard?
Whenever I see circuit diagrams they just show a ground off some components. When I'm designing on a breadboard should all of these go to the same negative bus on my breadboard in order to function properly? I've got one positive and one negative on each side (standard 6" Radio Shack model). Also, I would assume that a series circuit would be for those instances when you have no negative bus at all and need to ground back into the power supply as well? Thanks!
