Simple implementation of Graphical User Interface with cheap encoder

Interrupts are used to wake up Arduino from deep-sleep mode in lowpower implementations

Connections:
- PinA to D2 (interrupt is used)
- PinB to D4
- Button to D3 (2nd interrupt can be used)
100nF debouncing capacitors are used for PinA, PinB and button because in lowpower mode ATMEGA timers cannot be used
