warning message in tutorial because wiring diagram is misleading #429

We had someone in our community trying to install the visualizer. Apparently he miswired his strip, connecting voltage directly to his Raspberry, which is most likely dead now. In the linked wiring tutorial a rather rare strip is used where the data line is not in the middle, at least in their wiring diagram. However most strips are different. Maybe there is a different tutorial which could be linked instead, but a short warning about it in the readme should do for now.

Hey. Sorry about that fried RPi. By swapped you mean that data wire should be in the middle? Those are always labeled, but sure, additional warning can save few Raspberries.

Yes, data is usually in the middle. Even though it is labeled, beginners might miss it.
