Encoder read by BARRAGAN
Demonstrates the use of an encoder with the Encoder library Prints the encoder value

    #include <Encoder.h>

    int val;
    Encoder myEncoder;

    void setup() {
      myEncoder.attach(2, 8);  // ataches the encoder to pins 2 and 8
      myEncoder.write(0);      // set the encoder position to 0
      Serial.begin(9600);
    }

    void loop() {
      // Reads the position or angle of the encoder variable
      val = myEncoder.read();  // read position
      Serial.print("Encoder is at: ");  // print the position
      Serial.println(val);
      delay(100);  // wait 100ms for next reading
    }
