But these were not your standard WS2812B strips with data lines: all the LEDs were simply connected in parallel with just ... that send signals down a two-wire LED chain before, although as ...
The circuit in question ... with the aid of a 3.3 V regulator wired in parallel with the LEDs. The regulator must also be able to handle the full 24 V when the LEDs are switched on.
The current is different in different parts of a parallel circuit. In most buildings, the lights and sockets are all connected in big circuits but you can switch individual devices off ...
