I am making a project that uses a string of 50 ws2812 RGB leds. They are 5 volt. I am providing current to the LEDs using a fairly high amp wall wart converter. There is a common ground to the Arduino. The project is in development and I am powering the Arduino via the USB connection to my computer.…

Can I safely power arduino uno from 5V pin?
