Hello all, let me start by saying I am very new to arduino. I have purchased an arduino uno starter pack. I randomly watched a video on an arduino project and became very curious about how this works. For my first project I want to wire up smd5050 LED strip around my desk that I can keep on and control with the remote control that comes with the strip, but also turn on the arduino uno when I want the strip to flash to music. My idea is to take the power off the 5v rail off my PSU to power these LED's. My question is, is this safe for the arduino or is there a better solution? Also is there a schematic already done out there for this exact setup? I am not too sure how to wire this up. I guess I would be using a Sound Detection Sensor Module on the arduino for it to listen to music. I already have the code from a video I found on youtube.
Here's the LED strip I purchased: https://www.amazon.com/gp/product/B00B2F3KDQ/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1
Thanks.

That strip takes 2A per colour so to get white your power supply needs to provide 6A and at 12V not 5V.
To control that you need to use three logic level FETs, you can not connect them directly to an Arduino.

So instead of using MOSFET's. What If I used an LED Strip driver? Link to it below.

No current is specified as far as I can see, so it looks like the vendor has no idea what he is selling. I would avoid this and look for something with better information about what you are buying.
