Timer by BARRAGAN

Demonstrates how to create a timer to print a message every 7 seconds


unsigned long previousTime = 0;

void setup()
{
  Serial.begin(9600);
  previousTime = millis();  // mark the initial time
}

void loop()
{
  // if 7 seconds have passed since last mark
  if((millis() - previousTime) >= 7000 ) {  
     Serial.println("seven seconds have passed");  //print message
     previousTime = millis();  // mark again
  }
}
