But you should never turn off the power to a string of WS2812s when the data pin is connected up anyway or you will damage them.
Also you have been told before that you have to use a series resistor in the data line and a large capacitor across the supply, these should be on the diagram, as well as the power and ground connections to the nano.
Here is how to post an image image guide
Have a look at thread here
Conveniently, it contains all of;
- a suggestion to use imagebin
- The reason I’m using imagebin
- Two requests for the details on power surge protection, specifically resistors and capacitors.
The last one was never answered…maybe, just maybe because some people are too busy looking for everything that’s wrong with a post rather than making ANY attempt to be helpful.
I’m new. Telling me I need a resistor and a capacitor doesn’t help. I barely know what they do, but I’m vaguely aware they have different sizes.
Tom, again, thank you. Mike while I recognise your vast technical experience, it’s no use to me if you can’t deliver it without making me sit up and do tricks. I think it’s best you just ignore my posts, I won’t be offended.
