I have a string of 150 RGB LEDs (ws2812b) that I will be powering with a 5v, 10A power supply, like this.
I'll be controlling the LEDs with an Arduino UNO, and would like to power the Arduino off the same supply.
I have read that the 5v pin on the Arduino can be used for input power, but it needs to be exactly 5v since there's no protection circuitry on it. I tested the power supply with my multimeter and get 5.209v. Will I have any trouble, or should add a buck converter or something to aim for closer to 5v?
I have one other question... I was going to add a wall plate barrel jack to my enclosure to power both the LEDs and the Arduino, but most of what I see are rated for like 1A. Is that something I should worry about? Any suggestions would be appreciated.
