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 ...

The pixels draw a maximum of 60mA per pixel at 5VDC (20mA each for red, green and blue). These are individually addressable RGB LEDs. That means, we can make each LED turn any one of 16 million ...

[Jose] wanted to try to recreate the colorful pattern effects created by a kaleidoscope using an Arduino and an addressable LED strip. The build is actually pretty simple. The base is a disc of ...

[Patrick] was prepping for some future projects he had in mind, for which he will need a simple 2D array of addressable LEDs. While it is certainly possible for him to build his own LED array and c… ...

An Arduino can be used to test the life of any battery with less than 5 volts, Boxall says. So, for a quick way to see how much juice your AAA, AA, C, or D batteries have left, build this Arduino ...
