The WS2812 comes in two versions (WS2812 & WS2812B), and the most evident difference between the two types is pin configuration and internal structure. The WS2812 has 6 pins and 6 pads on the inside, ...

The pin parameter is an unsigned char should be the number of the Arduino pin that the LED strip's data input line is connected to. For ATmega2560-based boards such as the Arduino Mega, only the ...

This library currently supports any board based on the ATmega168, ATmega328P, ATmega32U4, or ATmega2560 which runs at 8 MHz, 16 MHz, or 20 MHz. The LED strip's input connector has two pins that should ...

Use the CCL peripheral of the ATmega4809 on the Arduino Nano Every board to create a WS2812B "NeoPixel" addressable RGB LED driver without bit-banging.
