5 x WS2812 LEDs + Arduino Nano Power Issues - General Electronics - Arduino Forum

Hello! I'm working on some fun Arduino Christmas presents for my family in the form of LED-lit acrylic signs. I'm encountering an issue in which the project works perfectly fine when powered via USB, but seems to have issues when using any other power source. I've got a very short strip of 5x WS2812B LEDs, which I'm powering from the 5V pin on the Nano itself. The power supplies I am using are variable, I can switch from 5, 6, 7.5, 9, and 12 Volts. It can supply up to 2.5 A so I wouldn't imagin
