    Can an Arduino and PWM circuit be used to create an arc generator and speaker?

    Yeah you're probably right. Also found a similar optoisolator on a swedish site (Im swedish), so thanks! The switch delay was low enough. But with the optoisolator, do I really need a transistor? The way I see it, the optoisolator is a kind of a transistor, right?

    Can an Arduino and PWM circuit be used to create an arc generator and speaker?

    Many thanks for reply skeptic! I haven't made my coil yet actually, need to figure out how I want the ratio between the turns of the coils. About the optoisolator, interesting component. However, the ones I could find had too much delay between the switch, the shortest I could find was about 6...

    Can an Arduino and PWM circuit be used to create an arc generator and speaker?

    Hello everyone. My first post so bear with me. I'm planning on buliding an arcgenerator (and possibly an arc speaker later on if this works) with my arduino and a coil. I'm relatively to electrical engineering, so there are a few things I need some help with. If I've understood things...
