After a back and the forth with a SparkFun rep, I learned that I wasnt getting enough power to drive the inverter and arduino board. Apparently the inverter I bought doesn’t integrate well with the El Escudo. So, it is mainly a power issue, which I’m still trying to sort out.
no, you’ll have to buy them separately and solder them onto the board.

oh the status led on el escudo is blinking, but not the el wire. hmmm
yup that was me! so i soldered headers to the el escudo and plugged in the inverter (the two wires labeled “3V” is input, right?). Nothing was blinking, the I think the board is getting power because I can here the inverter humming. Any tips on trouble shooting? Do you think doing a better soldering job will help?
I even programmed the status led to blink on the El Escudo, but it’s not blinking.
I’m prototyping for a larger installation, so I want to power El Escudo from the Arduino for prototyping purposes, but I’m not sure how to do that.
Would I need to connect the El Driver pinholes to the Arduino’s power pins?
I am using the Duemilanove and the 3V inverter sold by SparkFun (http://www.sparkfun.com/products/10201).
