Mike, you have hit the nail on the head mate.

Missing ground and as such circuit incomplete.

Excellent example of mind fixation. (this is a major problem for pilots and has been the cause of numerous crashes over the years) In my case, because I was feeling uncertain about the software I was totally fixated on that and not noticing that there was a fundamental error elsewhere..............a missing ground.

As is the case in airline crashes there was also more than one mistake............when ever I checked the signal I used an easy to get to 0V and of course that was not on the Arduino.

My sincere thanks to all involved but especially to Mike for your patience and thought processes.
