What's better than one rotary encoder? FOUR of them! but who wants to deal with that much code...when you can use seesaw instead? this samd09 firmware will read 4 encoders plus switches, and keep track of all the grey code transitions. it can even light up 4 neopixels - all over I2C for easy use with any microcontroller or microcomputer.
