Mbed + PIR sensor from coolcomponents.

Afternoon gents,

Im having some trouble with something that looks easy.

To cut a long story short, I have made a post on the mbed forum.

http://mbed.org/forum/mbed/topic/1419/

Are there any strange outputs from a PIR I should be aware of?

Stuff I understand:

  1. Passing 5v to it
  2. Goes Low when alarm is active
  3. needs a pull up resistor (set this on the mbed)

Thanks

dean
