Another quick wiring question
<< < (2/3) > >>

purpose..... um, to make it work.....  :laugh2:

Most people actually do daisy chain them all together.
With two leads, one from each end of the chain, going back to your ground.

The ground wire is sort of the return wire for the signals.  I am oversimplifying and probably slightly misleading, but what happens is that the micro switch connects the two wires when you press the button, the encoder senses that the wire for "button x" has been grounded and acts accordingly.  You could play your games by just touching the wire for the button you want to press to the ground terminal on the encoder instead of all this messy button stuff, but that would be a little unwieldy.  Somebody may chime in with a little more technical answer, but while I understand what it all does, I don't necessarily get how it all does it.  The reason that you daisy chain is that it is a lot less work than running a ground wire all the way to each switch.

Thanks for the answers I knew you had to do it for everything to work.  I just wanted a technically answer explaining it :)

Another advantage to daisy-chaining, if you loop both ends of the chain back to ground, is that if any 1 wire/connection fails, everything beyond it still has a path to ground and all your components still work.

I like to have a little of the wire sticking out.  This makes sure that the wire is fully in the barrell when you crimp it.
