This is one of my first Arduino projects, I’ve been using a Arduino Uno Wifi Rev2 to control a 16.4ft strip of Neopixels from a server that I coded. I have a 5V 15A power supply for the lights, and a 9V plug for the Arduino. A whole Arduino Uno Wifi might be a little overkill, but I figured I could always downgrade to a smaller microcontroller later.
It all works the way I like right now, and I have the power supplies separate, but my question is is there a safe way power it all off of one power supply? I’d like put all the wiring in a case, and I feel as though that having one source of power (and only needing one outlet) would be a better practice, and be better aesthetically.
Any tips would be helpful.
