// constants won't change. Used here to set a pin number:

const int add1 =2;
const int add2 =3;
const int add3 =4;
const int add4 =5;
const int signalout =8;

// Variables will change:
int ledState = LOW;  // ledState used to set the LED
// Generally, you should use "unsigned long" for variables that hold time
// The value will quickly become too large for an int to store
unsigned long previousMillis = 0;  // will store last time LED was updated

// constants won't change:
const long interval = 1000;  // interval at which to blink (milliseconds)
