// This example checks the state of the rotary encoder in the loop() function.
// The current position is printed on output when changed.

// Hardware setup:
// Attach a rotary encoder with output pins to A2 and A3.
// The common contact should be attached to ground.

#include <RotaryEncoder.h>

// Setup a RoraryEncoder for pins A2 and A3:
RotaryEncoder encoder(A2, A1);

void setup()
{
  Serial.begin(9600);
  Serial.println("SimplePollRotator example for the RotaryEncoder library.");
} // setup()


// Read the current position of the encoder and print out when changed.
void loop()
{
  static int pos = 0;
  encoder.tick();

  int newPos = encoder.getPosition();
  if (pos != newPos) {
    Serial.print(newPos);
    Serial.println();
    pos = newPos;
  } // if
} // loop ()

// The End
