Hello again everybody,
I just encountered a problem with a sensor that may be resolved by the answer to the following question: what is the maximum voltage that will be considered 0 logic on the Atmega8? I know that I should probably be able to find it on the datasheet, but I cannot for the life of me locate it. Here is the sheet if one of you pros wants to point me in the right direction:

P.S. For you curious types, my issue is that I have an IR emitter being cut off from a detector, but I'm only able to lower the signal to about 1.5 volts or so.
