I have a little problem with the blade
I made No. 1 by referring to some videos, but the Vendor told me to do it like No. 2. Which one is correct? I think there’s no problem with both, but NO. 2 is parallel, so the brightness will be weak.
What do you think about this? I’d appreciate it if you could give me some feedback
Both work.
For the data, I would prefer the second one since it only requires one resistor.
For + and -, either will work, (1) allows for slightly thinner wires, wile (2) requires less (but thicker) wires.
Wouldn’t the brightness be low?
only if you used the same thickness wire as #1 and just removed a pair.
The idea is you would compensate for only having 1 wire by making it fatter. like 22AWG is good.
