Thanks for the video. There is not much info out there specifying how to power arduino after uploading the code. Everyone always skips that step. In my case it will help me power 12v pc fans with a 12v 1amp and also powering the arduino. I'd hate to have two separate power supplies for a simple design. (Newby here)
Pretty sure you are using a WS2811 strip there? (not a ws28112b) Those older generation ws2811's had that "groups of 3" limitation, but use 12V, which makes more sense for longer runs.
Great video. Just a quick question. I am working with a WS2815 strip which is 12v. My understanding is that the Arduino pin output is 5v. So, it appears that the LEDs data channel can be 5v and it still works. My preference is to use an ESP32 where the output pins are 3.3v. I can step them up to 5v as I have done with the 5v strip I use, but wasn't sure if it needed to go all the way to 12v for the data pin with this strip. Your assistance is much appreciated.
I also noticed the LED's cutting group are in sets of three, while the WS2812B the cutting are single LED's. So I think you are 100% right this is the WS2811
So I can't use a 12v power supply on the 5v of the WS2812B? I was thinking of getting a 12v power supply because my WS2812B isn't capable of putting out all white on the LED's.
Won’t the 12v signal fry the arduino even though it’s only the ground and data pins are connected, should I put a resistor before I connect the ground to the arduino?
@@crazytom Sorry I do not understand. Can I put the 12V into the Arduino and run a separate power line to the 2 5M 12V Led Strips (WS2815), each Strip has 300 LED, are we talking 180 watts per Strip? and will the 480 watt power supply do the job?
@@alejandrissimo in my case, the computer was dead. I had to put a needle in some kind of reset button and then it started again. Not sure how not to have floating ground in such cases
This is NOT a WS2812B led strip you're using there. People watching this with a real 2812B strip like you advise WILL FRY IT. You're unintentionally spreading misinformation here.
