The Arduino WS2812b Controller Shield is a shield designed to offload the implementation of the WS2812b protocol to the shield. It is implemented on an ATtiny85, and the Arduino communicates with the shield over standard SPI. The code for the ATtiny85 can be found at https://github.com/k3jph/ws2812b-spi-controller

A simple voltage divider to showcase how to make parts. A voltage divider is a simple circuit which turns a large voltage into a smaller one. Using just two series resistors and an input voltage, we can create an output voltage that is a fraction of the input. Voltage dividers are one of the most fundamental circuits in electronics.
