WS2812B & Arduino. Earlier we controlled LED matrixes, strips and other complex LED projects bundled with countless interconnected wires with the help of multiplexers and shift registers. Now it is ...

To drive the LEDs, [Ole] is using an Arduino. Even though the WS2812s are individually addressable and only one data pin is needed, [Ole] is using five individual data lines for this matrix.

I’ve seen addressable strips constructed that use 12V but, in order to use that high of a voltage, the strips have to be built where you can only control every *3* LED’s.
