I'm a complete noob here. In fact, I don't even have an Arduino yet... I was just thinking about a project that I THINK would be pretty simple to do and figured I'd look into it first. I just want to make sure I'm not insane by oversimplifying this.
I have a TV with a powered USB port that powers a string of LED lights providing a groovy glowy effect around the TV. And, since both my wife and I are lazy, neither of us wants to get out of bed to unplug the blasted USB cable to turn off the lights.
I was thinking I could power the Arduino with the power from the TV (via USB) and then plug the string of LED lights into another USB port connected to the Arduino board. I would then control the power being sent to the LED Lights via my phone (probably by hitting some endpoint from my phone: e.g. http://10.0.0.1/off).
I'm assuming this is possible, but I really have no idea where to start or what parts or components I need, so I am humbly groveling at your feet hoping you could pass over a few crumbs.
