The SparkFun Qwiic Twist is a digital RGB rotary encoder breakout that is also able to connect to the Qwiic Connect System. The Twist takes care of all the various interrupts, switches, PWM'ing of LEDs, and presents all those features over an easy-to-use I2C interface.
One rotation in the clockwise direction for the rotary encoder increases the overall count by 24 and -24 in the counter-clockwise direction. The number of ‘ticks’ or steps you have turned the knob are all transmitted over I2C. The red, green, and blue LEDs are all set via software commands and can be digitally mixed to achieve over 16 million colors.
Sparkfun designed Qwiic Twist with an indent encoder which gives the user a great ‘clicky’ feel. Additionally, the encoder has a built in button so the user can select an GUI menu or element by pressing down on the it. Sparkfun has also written an Arduino library for the Qwiic Twist showing off all the different features of the Twist.
