Ok, I give up, I tried to solder together a timer to work with a Lamson PIR and found out how much I don't know about electronics. Lesson number one, don't pick up the soldering iron from the wrong end. Second, don't get a blob of solder in the middle of your circuit board, you can ruin your board trying to remove it. Question, is there a timing unit for sale completed or can someone put one together for me for a fee??? Any suggestions ?? Lew, with burnt fingers.
