Unique Projects with Digital Potentiometers

Interesting DigiPot!

Ok… Technically they are encoders.

This is 4 of them running over i2c, with a working 4 io gpio handler.

I use it to run LED strips,
Dial 1 is position
Dial 2 is color
Dial 3 is size
Dial 4 clockwise saves current pixel object
Dial 4 counter clockwise deletes current pixel object

The animation system draws the “objects” from an array that gets stuffed into a ws2812 buffer via DmA.
