// 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);

|

|
