Picture of Control EL Wire with an Arduino
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 

Step 1: Schematic

This is how to hook the circuit up:

 

I did this in a similar fashion but an led chaser board was used to sequentially switch the relays (instead of blinking leds). still working out the intermittent bugs though.

Thanks. That was cool but I never saw any pictures of the strippers!

Thanks for your suggestions. As far asi know you can't dim the EL Wire or do PWM.
Actually you can do both, see this incomplete and abandoned ( pretty much ) page for the pic 877. Code is C so should be understandable. Electronically the relay is replaced by a triac.

I think you need a reverse current protection diode in there as the relay is inductive.
How does this handle dimming of the EL wire?
