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... ;))
