//**********************************************************/ 
// Step-1: CONFIGURE VARIABLES 
//**********************************************************/ 
int motorPin = 3;       //this is a PWM capable pin 
int buttonPin = 8; 
int buttonState = LOW; 

//**********************************************************/ 
// Step-2: INITIALIZE I/O PARAMETERS 
//**********************************************************/ 
void setup()  
{  
  pinMode(motorPin, OUTPUT); 
  pinMode(buttonPin, INPUT); 
}
