    I just got this the other day, and hooked it up to a Duemilanove. I have 12v at the power connector, ground at the ground, and a 10k pullup resistor to 5v. I get a constant low signal when I try to read the signal digitally, but reading it with analog gives a reading of around 430 (a bit under 2.5v) when it should be detecting something, and around 250 (around 1.25v) when it shouldn’t. Does anyone know what I might be doing wrong? I stripped it down to have nothing but the Arduino and the PIR on the circuit, and reported the results with a serial line to my computer.

No public wish lists :(
