¾  R2WD_test 
Here’s an example ,we use it to test a car with two wheels.after this ,you will More thorough 
understanding of the library   
Simple code: 
#include <MotorWheel.h> 
#include <R2WD.h> 
#include <PID_Beta6.h> 
#include <PinChangeInt.h> 
#include <PinChangeIntConfig.h>      // Include the header files  
/* 
  Wheel1 ||-----|| Wheel2   
 */ 
irqISR(irq1,isr1);      // Intterrupt function.on the basis of the pulse  ,work for wheel1 
MotorWheel wheel1(9,8,4,5,&irq1,REDUCTION_RATIO,int(144*PI)); 
 //This will create a MotorWheel object called Wheel1  
 //Motor PWM:Pin9, DIR:Pin8, Encoder A:Pin4, B:Pin5 
irqISR(irq2,isr2);
