Not followed.

When it comes to driving WS2812 smart RGB LEDs the most difficult task is to overcome the extremely low timed time-slotting protocol as the LEDs don't have SPI/I2C/UART interface. One smart way to overcome this issue is to use the MOSI of hardware SPI at high speed. Please note though Arduino Nano is used, this is not an Arduino-based project.
