I'm trying to combine all the jumper wire connections to my Arduino into a single plug/socket, so that everything can be plugged or unplugged at once — neatly and without the risk of mixing up which wire goes where. This feels especially important because the Arduino is used for a job, and it may n…

Connect the connector to a separate "shield" or "carrier" board, which contains headers into which the Arduino board plugs. This way the Arduino board can be easily replaced without the need to do any soldering. Of course that only moves the problem to the "shield" or "carrier" board. However, a si…

[image] UKHeliBob: Dupont I guess I'd want to use this, but I wonder if there can be a way to prevent the Dupont connector being plugged in the wrong way, like how some sockets have built-in keying or notches to prevent incorrect orientation. I'm afraid that there can be people from a differe…

If you want to take it to extremes using the Dupont connectors being plugged in wrongly then you can Make the multi pin plug asymmetrical by not using one or more of its positions and block those positions on the header socket too. Block all of the remaining unused header sockets on the Uno to pre…

What'd be used to block said positions on the header socket? The application of the connectors is a running arcade machine that relies on my Arduino program as its "CPU".

For this solution, what'd you do with the Arduino's female header, or what kind of Arduino do you use for said board that is plugged with the mating connectors?

would take a difficult time in case the Arduino is damaged and that it has to be replaced with a new one, and it likely would have the people there other than me not knowing how to integrate the replacement Arduino on said machine

This is pretty much what you would find in an industrial control cabinet. Screw terminals and the ability to change out the Arduino. Pretty easy to design your own PCB and get them made for a few $$

Guess unlike the Arduino itself (which may be replaced), shield boards can be modified and stay like replacing the female headers in said shield board with a keyed socket, right?

How can I turn all Arduino jumper connections into one unified plug?

The image above is a socket, male/female. Somehow you need to connect the wires to ANY type of socket...
