Cheers for the replies.
Not had chance to have a look today, was a bad day at work and minecraft got the better of me, Amazing how something so simple can be so time consuming. Got in at 6, just realised the time and off to be lol
Will check this out tomorrow, but in the meen time, only things different are that the batteries went super flat (for the TMP36) and I put new ones, in, nothing else has changed.
I burned the sketch to another mcu and it made no difference, ut will try through a resistor as Riddick says.
Cheers once again.
