In this instructable I will show you how to control EL Wire with an Arduino. 
What you will need:
EL Wire and Inverter - I recommend http://ez-el.com/ez-el-wire/10ft-ez-el-wire-3v-inverter-kit/
A
rduino or any micro controller that can control a relay
SPDT Micromini Relay 5V - I recommend Radio Shack 275-0240
Wire
Heat Shrink Tubing or Electrical Tape
General Purpose PC Board
Tools:
Soldering Iron and Solder
Wire Cutters and Strippers 

Schematic

This is how to hook the circuit up:

Wire Up the EL Wire

First you need to disconnect the power wires from the inverter leading to the EL Wire like shown in the picture. 
Next solder the ground wires together. 
Now connect the voltage wires to the relay as shown in the schematic. 
You might want to solder the wires and the relay together on a small PCB. 

Connect the Relay to the Microcontroller

Lastly, connect the coil wires to the Arduino, just like you would connect an LED. Refer to the schematic for help connecting. 
Before you use this be sure to power on the EL Wire inverter. Make sure is is in a non blinking mode.  
Any code that works with an LED will work with this hack.
