I want to run a strip of 300 12V LEDs (Adafruit Neopixels with WS2811), with my Arduino. Is it safe to connect a follows, or is there some "separation" between voltage levels needed?
- 5V voltage/out and ground (from converter 1) to Arduino Voltage-in and ground.
- 12V voltage-out (from converter 2) to LED strip voltage-in.
- 12V ground (from converter 2) to Arduino ground and LED strip ground.
- Arduino data pin to LED strip data pin.
