Thanks Darrel. That is an awesome gadget. Is there any way to get you to replace d2 and d3 with variable resistors (or fixed if need be) and bypass the 200 ohm on the pin? This way it will be closer to the other circuit. I would love to test it (and yes, I am trying to use your sim instead of my breadboard) I think a more approiate value would be 0-1000 ohms. If not, its all good.
