I am making a project that uses an Arduino nano and a sound detector module to power a 1m LED strip. I got the idea from this video and I am not sure how to power it. My LED strip flashes for a split second and turns off, and people say that the usb power source I am using is not enough power. I am worried though that if I use a more powerful power source that it will fry my Arduino. I am very new to this and I have no idea what to do.
