I know this is a noob question, but I'm kind of struggling to find an answer (maybe because there isn't the one I'm looking for). I have a 5v 15A power supply that I plan to use to power some WS2812B lights I have in a project, and I was hoping to find a way to power my arduino off this same power supply. From what I can find, the only 5v inputs on the arduino are the usb and the unregulated Vin. Since my power supply comes from the wall, I assume it's unregulated. Is there a way to either regulate the input wihtout losing voltage, or maybe I could solder a usb cable to wires that connect to the power supply and plug that into the usb input?
