   This is an Arduino sketch for RotaryEncoder library using interrupts
   written by : enjoyneering79
   sourse code: https://github.com/enjoyneering/
   This sketch uses interrupts, specials pins are required to interface
   Board:                                    int.0  int.1  int.2  int.3  int.4  int.5            Level
   Uno, Mini, Pro, ATmega168, ATmega328..... 2      3      x       x      x     x                5v
   Mega2560................................. 2      3      21      20     19    18               5v

   PCF8574 chip uses I2C bus to communicate, specials pins are required to interface
   Board:                                    SDA                    SCL                    Level

   Leonardo, Micro, ATmega32U4.............. 2                      3                      5v
   Digistump, Trinket, ATtiny85............. 0/physical pin no.5    2/physical pin no.7    5v
   Blue Pill, STM32F103xxxx boards.......... PB7                    PB6                    3.3v/5v
   ESP8266 ESP-01........................... GPIO0/D5               GPIO2/D3               3.3v/5v
   NodeMCU 1.0, WeMos D1 Mini............... GPIO4/D2               GPIO5/D1               3.3v/5v
   ESP32.................................... GPIO21/D21             GPIO22/D22             3.3v
   NOTE:
   - LOW     interrupt trigges whenever the pin is low
   - HIGH    interrupt triggers whenever the pin is high (Arduino Due, Zero, MKR1000 only)
   - CHANGE  interrupt triggers whenever the pin changes value
   - RISING  interrupt triggers when the pin goes from low to high
   - FALLING interrupt triggers when the pin goes from high to low
