CLK (A pin) any microcontroler intput pin with interrupt -> in this example pin 16
DT (B pin) any microcontroler intput pin with interrupt -> in this example pin 14
SW (button pin) any microcontroler intput pin with interrupt -> in this example pin 13
GND - to microcontroler GND
VCC microcontroler VCC (then set ROTARY_ENCODER_VCC_PIN -1)

***OR in case VCC pin is not free you can cheat and connect:***
VCC any microcontroler output pin - but set also ROTARY_ENCODER_VCC_PIN 25
in this example pin 25
