My original question asked if I had it right or if I needed to make the resistors bigger. Suggestions were made to make the voltage smaller. My question is that with 2.5 volts, will that trigger the input? For a digital signal, you need a 1 or 0, or in this case, 5 volts or 0 volts. Am I missing something?

I am using the 16F819. After reading the other article (link that was posted), I figured I would use the VD to a transistor to trigger the input. I just don't want to blow anything up.

Thanks for your help thus far. I just want to understand it better.
