This build is using a custom driver with 3 channels of 2x7135 IC’s connected to a Attiny85 for generating the PWM signals, there is also space on the board for an ADXL335 accelerometer but at first moment I’m phasing the project with tail-switch UI as MVP.

The current UI is:

Color pick mode:

1 tap: Step the hue forward

2 taps: Step the hue backwards

3 taps: Resume animation mode on last speed or preferred speed

Animation mode:

1 tap: Lock the hue and switch to color pick mode

2 taps: Increase animation speed and also increase hue step size on color pick mode for faster search

3 taps: Decrease animation speed and also decrease hue step size on color pick mode for more granularity

5 taps: white mode

6 taps: enter brightness config mode, keeps hue or animation or white mode:

\- 1 tap: double brightness up to 100%

\- 2 taps: halve brightness up to 0.78%

\- 3 taps: saves and exit brightness config mode

8 taps: toggle default mode (color picker or animation)

16 taps: Reset preferences

Cold boot: Starts on a “random” Hue every time! (this is hard!)

And as I’m basically driving the hue here with the UI, this got to be the driver’s name!
