@Robo, your edit of the opening post (which I happened to have read before you changed it), renders UKHB’s reply #1 meaningless and makes him look crazy. When you do need to retract or correct something you said, I think it’s better to leave it in but
strike it out (perhaps with an explanation) or to add a new post. That way, the thread still makes sense; right now it doesn’t.
That said, if you’re using breadboard, it’s easy to share like you say, just by using the (usually) red and blue power rails as busses. Just take 5V to one, Gnd to the other, and wire in as you need. (Subject, of course, to current being available…)
If it’s more permanent, you could solder wires together or use connector block with jumpers on one side.
