Thank you, I did find a video showing that, but this page is much better. Mikek
I may need a little more input, I have a voltage the sets at 5V, then drops to 2V. A negative going pulse. That is the 555 trigger on Pin 2. I need the output to go low when the input goes low.

positive swing on the schmitt trigger input to cause the negative output. Mikek
