== Software ==
You can download the Arduino sketch here:\\
http://code.mios.com/trac/mios_arduino-sensor/browser/trunk/Arduino/LightSensor

This sensor sleeps most of the time. You can change the sleep interval by updating SLEEP_TIME define at the top of the file. 

== Wire things up ==

Follow the instructions in ConnectingRadioModule to connect radio module.

Connect the digital AO (Analog Out) of the light sensor to analog input 0 of Arduino board.  
Connect VCC to +5V of the Arduino board. GND to GND.

== Hardware - Purchase guide ==

To build this sensor you'll need one arduino + radio specified in the base kit found here:\\
http://code.mios.com/trac/mios_arduino-sensor/wiki/WikiStart#Buyingguide\\
With the following additional parts:

1x Light sensor\\
