Amoque,

Thanks for your thoughts and empathy from a fellow "enthusiast."

I have read some related posts that the forum software provided presumably due to the tags I defined. There were also some good insights though most of the users there had sensors which were much more sophisticated devices than my lowly reed switches. One person recommended double sampling and rejecting the highs to short to be legitimate by delaying some micro seconds between the samples. I had thought that perhaps using the "Button" command in PBP3 would help de-bounce the input.

I will try running with battery power. Presently I have a 5vDC wall type supply with no ground. I am also going to heavily shield the wires from the reed switches and attempt to use best practices in grounding the shields. I also read elsewhere on the net that I might have to reference my main control board ground plane to the same "earth" ground if I am going to shield/ground all devices.

I have the project fully drawn and documented but I thought due to its size, I would submit that as a last resort.
