LIGHTS What You'll Need
Raspberry Pi Fully loaded with RasPiViv installed	Relay Power Box Assembled in previous section	Jumper Wires Used to connect the sensors to the GPIO	Computer For SSH access to your Raspberry Pi
	LEDs Used to create Moonlight effect	Resistors 10 Ohm 1/2 watt
Installing Schedules and LED moonlights Now that we have our relay driven power outlets we can schedule them to turn on and off using a cron job In this build we have two light hoods with LED Moonlights that power on & off automatically during moonlight mode
	Day Mode Normal Vivarium lighting mode	Night Mode LED moonlighting mode
STEP 1 Create a cron job to schedule your lighting. In my build the lights pwer on at 8am and off at 8pm * 8 * * * wget -q http://localhost/html/on.php * 20 * * * wget -q http://localhost/html/off.php
STEP 2 Connect the LEDs to a ground pin and positive to GPIO 4 (physical pin 16) All LEDs are wired in parallel with a single resisitor and powered by the GPIO pin
STEP 3 Open a browser and visit your Raspberry Pi Vivarium Controller "Manual Controls" page and test your LEDs NOTE: Buttons will show what will happen when clicked, not the current state of the device.
STEP 4 Wire and mount your LED moonlights
FINISHED Next up, we will install fans and learn how to set humidity
