But I have discovered an easier way which wouldn't require a custom USB cable, I could simply power the Arduino from my PC's motherboard USB header via a standard cable and the LED strip from the Molex seperately. The only connection between these two would need to be GND and led strip data line I believe. So I would never need to try share a 5Vs connection between the 2 components. | |

| Apr 22, 2017 at 6:51 | comment | added | Brandonm | Wow thank you for such a detailed and well thought out explanation. Really appreciate that since, I know very little. To answer you question about the LEDs I'm not entirely sure how to answer it best. This is the project I'm using as an example for mine. github.com/CalcProgrammer1/KeyboardVisualizer right now there is no switching on my led strips connected to the digital output, ground and the 5V pin that I am aware of. Seems to run fine with just the 1 strip of 30 LEDS so I'm assuming that the strip itself is handling this? | |
