So, I modified the circuit and put a 150k Resistor on R1 (didn't have 180k) and a 1k to ground (R2). I am triggering on anything hitting around 0 volts. That is not very nice. I think R1 will have to get a Variable Resistor instead of a static resistor. Not sure about putting a Pot on a voltage divider circuit but oh well here we go. Probably a 470k pot going to pin 5 and then ground going into the 1k resistor(R2) to ground.
I feel I am very close to getting my trigger point correct.
Its just I think my trigger point is actually hitting above 0 volts not just in the negative area. Doesn't seem very logical thought. My scope seems pretty determined that it is.
Feel like I am chasing my own tail on this. LOL
