Use the RPi as an interface to the Passive Infra-Red (PIR) Motion Detector.  (Aka pyroelectric IR).  Prints a message to the screen when it detects warm body motion.

MATERIALS
- Raspberry Pi (and Pi power supply)
- PIR Motion Detector

WARNING: Warning: mis-wiring or mis-programming your Pi or miswiring of accessories can ruin the Pi and accessories.
Information/drawings offered as is.   Use at your own risk.   If you don't know, learn first.
