I have a 256 and using many of the pins for various things. I am using a connector for the DIL pins. What is the chance that the connections will fail over time? I hace a couple of +5 inputs that go crazy every once in awhile and I am wondering if the connection to the pin is faulty.
Thanks
It is a mystery
Well I don't even know where to start! If I knew what were talking about it might help. There are millions of devices that have pins, narrow it down to 1 and we may be able to help you assuming it is an Arduino device.
I am just asking this question to see if it is a known issue. I know some wiring issues with low voltage can corrode. I was taught long ago that the wiring methods for phone cabling were developed with 48VDC as the carrier of audio. If the connection got wet or was in a high humidity the current would renew the connection. The issue I am having is that a contact that provides +5 vdc to a pin sometimes appears to open and close many times in a few seconds. the contact is a sealed reed switch. It is on a garage door. If the chances of a connector on those pins going bad is small then I will look elsewhere in my setup. It is actually the only issue I have with the inputs to the Arduino.
Its still a mystery.
The probability of the mystery thing having a problem with the mystery connection being more likely than some other mystery problem is (?x?):?
Single duponts fall out quite easily. To build a project that lasts you need a screw terminal shield for signal and power. This is the solution i found for a Mega 2560:
I also add 3D printed shrouds over the module end of cables to gang the pins, ID pin 1, give a place to label, and increase retention.

That shield is probably something I need to look into. My board is a Mega 2560. Is that shield readily available or did you create it yourself?
I know this is a mystery to fathom to some. I was looking for the probability of it being my issue. so I will just shotgun the problem and replace what I can, where I can.
Thanks
I found the shield on Amazon. Alot cheaper than I expected. Your installation looks pretty well thought out and clean.
The screw terminal shield is under $20 (assembled) from Wal-Mart.
The Power Distribution Board (PDB) is built from under $15 of parts.

The rest of the stuff is 3D printed.
I was a manufacturing engineer before I retired.
I found the same Shield kit on amazon for $12 never thought to look at Walmart :)) Your perf panel project looks nice. I think I have that part covered already.
Thanks again
