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 3: 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.

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?
