+// If you define ENCODER_DO_NOT_USE_INTERRUPTS *before* including
+// Encoder, the library will never use interrupts.  This is mainly
+// useful to reduce the size of the library when you are using it
+// with pins that do not support interrupts.  Without interrupts,
+// your program must call the read() function rapidly, or risk
+// missing changes in position.
+#define ENCODER_DO_NOT_USE_INTERRUPTS
+#include <Encoder.h>
+
+// Beware of Serial.print() speed.  Without interrupts, if you
+// transmit too much data with Serial.print() it can slow your
+// reading from Encoder.  Arduino 1.0 has improved transmit code.
+// Using the fastest baud rate also helps.  Teensy has USB packet
+// buffering.  But all boards can experience problems if you print
+// too much and fill up buffers.
+
+// Change these two numbers to the pins connected to your encoder.
+//   With ENCODER_DO_NOT_USE_INTERRUPTS, no interrupts are ever
+//   used, even if the pin has interrupt capability
+Encoder myEnc(5, 6);
+//   avoid using pins with LEDs attached
