I have a motion detector that I want to get info to my computer. I am using LPT
port to input data. I could not follow what tripped motion. It has a LED which
lights up when it detects motion. I measured 1V DC when its "off" and 1.5 when
it's "on".
What kind of cirquit should I have? On the LPT side a register is on when a
couple of pins are short cirquited.
