Qwiic Twist Hookup Guide

Connecting Colors
One of the more advanced (but really handy) features of Qwiic Twist is the ability to connect the color control to the knob movement. What this means is that you can have the red LED brightness increase or decrease as the user turns the knob without sending commands to the Qwiic Twist. This greatly increases the responsiveness of the knob illumination and dramatically reduces I2C traffic.
In the above photo we have connected blue to increase brightness by 10 for every tick increment, and connected red to -10 per tick. The color changes automatically without the need for intervention from the I2C master. The color connect values are stored in the Qwiic Twist and will be loaded after each power-on.
See Example4 of the SparkFun library for a full demonstration.
