Sample to demonstrate waking an Arduino microcontroller using messages from the serial port.
The LowPower library (https://github.com/rocketscream/Low-Power) is used to put the microcontroller to sleep.
The PinChangeInt library (https://code.google.com/p/arduino-pinchangeint/) is used to wake the device.
Both libraries are included in the project files & should be moved into your Arduino libraries folder.
The MegunoLink Pro project provides a button to wake and sleep the micro. More information is available at: http://www.MegunoLink.com/
