Hi all,

I've just purchased EL wire 3m, 3v inverter and escuduo, connected this all to a 3v AA battery pack and nothing is happening.

Can someone take a look at the photo and tell me what I need to do to get this working?

Thanks!

Your EL Escudo shield is not plugged into an Arduino.  You will have to solder in some header pins to connect the EL Escudo to the Arduino.  Then you need to write a program to turn on the channel you have EL wire connected to.

If you just want to light the EL wire, take out the EL Escudo shield and jumper the driver connector to the EL wire connector.

Whoops! That makes sense! Have I done the inverter + battery wires right though?

Since you are using a 3-volt inverter it looks like it is hooked up correctly: using only the Inverter Output socket.  If you were using an inverter that could use the same voltage as you are supplying to the Arduino battery jack you could use the "Raw Voltage" socket to supply power to the inverter.

To use the shield you'll need to  solder in some header pins, connect the shield to an Arduino, and provide power to the Arduino (typically through the power jack or USB cable).

Hi,

Do I connect any of the Digital Outs on the Arduino to the Analog Ins on the Escudo? Or is there a specific number I should use?

I don't yet have external power for the Arduino other than USB. What sort of cable should I be looking for?

I have the 3v Inverter http://littlebirdelectronics.com/products/el-inverter-3v

Should I be using the 12v inverter? http://littlebirdelectronics.com/products/el-inverter-12v

Do I have to power the Escudo and Arduino separately (2 wall plugs)? Assuming I use the 12v, are you saying I should use "Raw Voltage"? A bit confused, sorry!

Also, I need the Sequenser to made it blink/fade, yes? Does that plug into the Escudo? The Escudo just powers multiple EL wires doesn't it?

Thanks for the help - really useful.
