I'm looking at this product here:http://www.adafruit.com/products/189
But I was wondering what the delay means exactly... The websites says the delay is "0.3-18 seconds" which I'm guessing .3 is the lowest and 18 is the highest and you turn the time "dial" that is on the board to choose.
So my question is, does it take 0.3 seconds for it to notice movement or 0.3 seconds for it to take an "image" to compare to check for differences (and then movement is detected instantaneously?)?
With what I'm doing it is crucial that the arduino knows about the movement almost instantaneously. Time is a big factor.
Thank you very much.
