I'm using an arduino to control 4 pieces of EL wire for a jacket. I have an inverter for AC power and using optoisolators and triacs to control when the lights turn on and off. Push buttons are meant to turn each light on or off. I prototyped this circuit using LEDs and the buttons worked fine. Now that I've switched to AC power control, the buttons seem to be staying on HIGH rather than switching to LOW when released. I've included an image of how my circuit is wired - note* optocouplers...
