With Arduino WS2812 LEDs are controlled in a very easy way. They are addressable RGB LEDs with a built-in chip and therefore occupy only a single digital output of the Arduino board. They are even available as RGBW (red-green-blue-white).<\/p><\/blockquote>\n\n\n\n

If you want to control LEDs with Arduino, then you quickly reach the limits of the available channels. Straight RGB LEDs each require three valuable analogue channels (red, green, blue).<\/p>\n\n\n\n

The WS2812 LEDs provide an elegant solution. They have a built-in controller. A data signal from the Arduino board then determines in which color the controller should light which LED. In addition, many WS2812 LEDs can be connected in series.<\/p>\n\n\n\n

Where can I get it?<\/h2>\n\n\n\n

There is a bunch of cool options. You can get the LEDs as stripes, rings, single dots or on a chain. <\/p>\n\n\n\n
