I am looking at purchasing a NeoPixel Ring for a project, but need it to work without an Arduino. Once the NeoPixel has been programmed by the Arduino, will it function when powered without the Arduino? I am not looking at changing colors or anything, I want to set the LEDs to solid red and not change.
I have found in the Adafruit website that it says "NeoPixels don’t just light up on their own; they require a microcontroller (such as Arduino) and some programming." But is this only to get them working initially, or do they require an microcontroller permanently?
