Encoder Diagram
====Diagram for UNO====
====Interrupt Port with Different Board==== Notcie:attachInterrupt

For example,with UNO board, you want to use interrupt port 0 int.0 . You should connect digital pin 2 with the board. So, the following code is only used in UNO and Mega2560. If you want to use Leonardo or Romeo, you should change digital pin 3 instead of digital pin See the link for detail

Encoder Sample Code
//The sample code for driving one way motor encoder const byte encoder0pinA = 2;//A pin -> the interrupt pin 0 const byte encoder0pinB = 4;//B pin -> the digital pin 4 byte encoder0PinALast int duration;//the number of the pulses boolean Direction;//the rotation direction
void setup

Serial.begin 57600 ;//Initialize the serial port EncoderInit ;//Initialize the module
void loop

Serial.print "Pulse:" Serial.println duration = 0 delay 100 ;
void EncoderInit

Direction = true;//default -> Forward pinMode encoder0pinB,INPUT attachInterrupt 0, wheelSpeed, CHANGE ;
void wheelSpeed
int Lstate = digitalRead encoder0pinA if encoder0PinALast == LOW && Lstate==HIGH
int val = digitalRead encoder0pinB if val == LOW && Direction

Direction = false //Reverse else if val == HIGH && !Direction

Direction = true //Forward encoder0PinALast = Lstate;
if !Direction duration++ else duration--;
