Project 36: PIR Motion Sensor
This project shows how to use a PIR motion detector
that sends an email whenever motion is detected.

Challenges:
1. Add a blinking Led to indicate motion is detected.
2. Play a warning tone when motion is detected.
3. Use other types of sensors
4. Send yourself an hourly temperature/humidity reports via email.
