Hi,

I got a 3V EL interver and 3m of blue EL wire. I found out the 3V output of the Arduino board is sufficient for it to light up.

It it possible (and a good idea) to control the EL inverter to the arduino power supply and control it with a digital pin?
Or, could it even be powered by the signal of a digital pin?

(Yes I am quite noobish with electronics, please type your answer loud and slowly...    smiley-wink)

CrossRoa, I can read you loud and clear!

It is this 3V EL inverter: http://www.sparkfun.com/products/10201
Datasheet: http://www.sparkfun.com/datasheets/Components/LED/SPECIFICATION%20of%203V3M%20-%20%E5%89%AF%E6%9C%AC.pdf
And this 3m length EL wire: http://www.sparkfun.com/products/10195
Datasheet: http://www.sparkfun.com/datasheets/Components/LED/Technical%20Information%20of%20Flexible%20Neon%20wire.pdf
and an Arduino UNO

KE7GKP, the board is neither sweating nor smoking, and still alive. I have seen the EL Escudo and other EL shields but am wondering whether I can spare the expenses.

KE7GKP, thanks a lot for your advice and explanation of the UNO board! This pretty much means I should have used relays/optoelectric couplers many times before  smiley-roll-blue

I'll have  close look at the UNO datasheet and get an ampmeter right away...
