Wiring home switches
« on: January 21, 2017, 11:41:20 AM »
Ok so I think I have read every topic we have on homing switches.  I am super afraid of letting out any of my magic smoke so soldering on my laser toy is scary.  I know they need to be put in parallel on the D9 pin.  I saw how gallant @ggallant571  (I think) wired his on the backside (Picture below) but I will screw that up for sure.  Then I saw how @Johnb63303 did it by soldering on new female headers on his nano.  I like that option but that is wayyyyy more soldering for me to screw up.  Does anyone else have any diy easy wiring solution for home switches?

You could grab some pcb like this http://www.banggood.com/5Pcs-7x9cm-PCB-Prototyping-Printed-Circuit-Board-Prototype-Breadboard-p-944697.html?rmmds=search, put some female headers on it with long pins. Put that in the controller board and put the nano into the "wing shield". You can then solder additional headers onto the pcb or even terminal.

If you don't want to solder to the board, put a header between the Nano and board and bend the D9 pin at 90 degrees. Then you can solder to the header.

Buy an L8 or build one of my DLCM boards. They have headers.

The DLCM board has longer headers and is easier to connect to.

Can you post a link to the DLCM board?

You may be able to use a Screw Shield, the original Nano version had through pins, the v2 doesn't but you can use the Uno one with minor mods.

Ok so I have a header between my L7 and the nano.... so what you are saying is pull out my nano and bend the d9 pin so it does not run into the header but all the other pins do.  Then solder to the nano? or solder to the header connected to the board? 

FYI I hate wiring! I'm a mechanical guy not an electrical guy!

Can folks post photos of where and how you installed your home switches?

You don't bend the Nano pin, you bend the header pin so it's totally reversible and worst case you mess up the header.

I have several of those, if you used the headers with long leads they would be perfect.

I don't have the best soldering skills either. Instead of trying to solder two wires to one solder pad on the bottom of a pcb, I'd solder a single wire and use it as a jumper.

Zax, I'm curious why do you keep recommending running X and Y in parallel, when is probaby just as easy (or easier) to wire up to individual pins?

@ThothLoki - Thanks for posting the Nano adapters. Just ordered a couple. Look perfect for prototyping.

I think I'll grab a few myself...question: how do wires attach? screws or via spring clamp?

UPDATE: I see from another listing it is screw in to hold the wires.
